Description

明細書 繊維強化樹脂成形体の製造装置、 およびその製造方法 技術分野  Description Apparatus for producing fiber-reinforced resin molded article and method for producing the same
この発明は、繊維強ィ匕榭脂パイプなどの繊維強化榭脂成形体の製造装置、および その製造方法に関するものである。 背景技術  The present invention relates to an apparatus for producing a fiber-reinforced resin molded article such as a fiber-reinforced resin pipe, and a method for producing the same. Background art
従来、繊維強化樹脂成形体の 1つである繊維強化樹脂パイプは、 金属管、 コンク リート管に比べて軽量であることから、施工性に優れており、 このため、広く普及 している。  Conventionally, fiber-reinforced resin pipes, which are one of the fiber-reinforced resin moldings, are lighter in weight than metal pipes and concrete pipes, and have excellent workability, and are therefore widely used.
このような繊維強化樹脂パイプは、軸方向に移動しつつ周方向 回転する芯型の 周囲に、複数本の周方向強ィ匕用長繊維補強材を連続的に卷回するとともに、下側と 上側に巻回される周方向強ィ匕用長繊維補強材の間に、軸方向強ィ匕用長繊維捕強材を 周方向強化用長繊維捕強材に交差するように規則的な蛇行形状で連続的に供給し、 これらの長繊 ϋ補強材に重合性樹脂組成物を含浸させ、重合性樹脂組成物を熱硬化 させることにより製造されていた（例えば、特開昭 5 6 - 1 0 4 0 2 7号公報参照)。 しかしながら、前述した繊維強化榭脂パイプは、周方向強化用長繊維補強材の層 と軸方向強化用長繊維補強材の層とを比較すると、軸方向強化用長繊維補強材の層 の樹脂比率が高いため、かつ、軸方向強ィ匕用長繊維補強材は、規則的に蛇行して供 給されること力ゝら、その変曲点において、周方向強化用長繊維補強材と略平行とな り、補強繊維が集中するため、急激な重合反応時に周方向強化用長繊維捕強材層と 軸方向強ィ匕用長繊維禰強材層の間において、特に、軸方向強化用長繊維補強材の変 曲点部分に集中してクラックが入るおそれがあつた。  Such a fiber-reinforced resin pipe is formed by continuously winding a plurality of circumferential reinforcing fibers for a circumferentially rotating core while moving in the axial direction while simultaneously winding a plurality of the reinforcing fibers. A regular meandering is performed between the circumferential direction reinforcing fiber reinforcing material wound between the upper side and the circumferential direction reinforcing fiber reinforcing material between the circumferential direction reinforcing fiber reinforcing material. It has been manufactured by continuously supplying in a shape, impregnating these long fiber reinforcing materials with a polymerizable resin composition, and thermally curing the polymerizable resin composition (see, for example, Japanese Patent Application Laid-Open No. Reference is made to Japanese Patent Application Publication No. However, the fiber reinforced resin pipe described above shows that the resin ratio of the layer of the axial reinforcing long fiber reinforcement is compared with the layer of the long reinforcing fiber reinforcement for circumferential reinforcement and the layer of the long fiber reinforcing material for axial reinforcement. Is high, and the long-fiber reinforcing material for axial reinforcement is supplied in a meandering manner, and at the inflection point, is substantially parallel to the long-fiber reinforcing material for circumferential reinforcement. Since the reinforcing fibers are concentrated, the length of the reinforcing fiber between the circumferential reinforcing fiber layer and the reinforcing fiber layer for the axial strengthening is particularly increased during the rapid polymerization reaction. There was a risk of cracks being concentrated at the inflection points of the fiber reinforcement.
このような問題点から、軸方向強化用長繊維補強材に代えてチョップドストラン ドを用いて繊維強化樹脂パイプを製造することが現在採用されている。具体的には、 重合性樹脂組成物を芯型上もしくは含浸槽にて含浸させた周方向強化用長繊維捕 強材を芯型に卷回するとともに、必要に応じてチョップドストランドを芯型上に振 りかけてパイプ状に賦形し、賦形後にヒータなどにより重合性樹脂組成物を硬ィ匕さ せて繊維強化樹脂パイプを製造するものであり、この結果、チョップドストランド がほぼランダムに分布し、繊維方向の集中によるクラックの発生を防止することが できる。 Due to these problems, chopped strands are used instead of long fiber reinforcing materials for axial reinforcement. It is currently employed to manufacture fiber reinforced resin pipes using metal. Specifically, the long fiber reinforcing material for circumferential reinforcement, impregnated with the polymerizable resin composition on a core or in an impregnation tank, is wound around the core, and the chopped strands are placed on the core as necessary. To form a fiber-reinforced resin pipe by shaping the polymerizable resin composition with a heater or the like after shaping, and as a result, the chopped strands are almost randomly formed. It is possible to prevent cracks due to distribution and concentration in the fiber direction.
ところで、 このようにして繊維強ィ匕榭脂パイプを製造するに際しては、次のよう な問題点がある。  By the way, there are the following problems in producing the fiber-reinforced dagger pipe in this way.
第 1に、重合性樹脂組成物が、常温以下で反応が開始される低温反応型重合開始 剤によって重合するようになっているため、重合完了までに時間がかかり、生産性 が低い。  First, since the polymerizable resin composition is polymerized by a low-temperature reaction-type polymerization initiator that starts a reaction at room temperature or lower, it takes a long time to complete the polymerization, and the productivity is low.
第 2に、余剰の重合性樹脂組成物を芯型などの下方に設けた容器で受けて再利用 を図るようにしている力 重合性樹脂組成物には、常温以下で反応が開始される低 温反応型重合開始剤が配合されているため、常温で放置している間も硬化が進行し、 十分に再利用が図れない。また、回収された重合性樹脂組成物にチヨップドストラ ンドが混入するため、チョップドストランドを除去する必要があり、作業効率が悪 い。  Secondly, the force of receiving excess polymerizable resin composition in a container provided below, such as a core mold, so that the polymerizable resin composition can be reused. Since a temperature-reaction type polymerization initiator is incorporated, curing proceeds even when left at room temperature, and it cannot be sufficiently reused. Further, since chopped strands are mixed in the recovered polymerizable resin composition, it is necessary to remove the chopped strands, and the working efficiency is poor.
第 3に、チヨップドストランドが振りかけられる直前に、ガラス繊 ロービング をチヨッパーで切断してチヨップドストランドを得るようにしているため、切断時 および振りかけ時に、チョップドス ランドが作業場内に飛散し、作業環境が悪化 するおそれがある。 したがって、大がかりな排気設備などが必要となり、設備コス トがかかる。  Thirdly, just before the chopped strand is sprinkled, the glass fiber roving is cut with a hopper to obtain a chopped strand, so that the chopped strand scatters into the workplace during cutting and sprinkling, The working environment may deteriorate. Therefore, large-scale exhaust equipment is required, which increases equipment costs.
第 4に、チヨッパーの刃の交換作業等も行わなければならず、作業が煩雑である。 本発明は、 このような問題点に鑑みてなされたもので、チヨップドストランドを 用いることなく、重合反応を短時間で完了させてクラックのな！/、繊維強化樹脂成形 体を簡単に製造する繊維強化樹脂成形体の製造装置、およびその製造方法を提供す ることを目的としている。 発明の開示 Fourth, the work of replacing the blade of the chopper must be performed, and the work is complicated. The present invention has been made in view of such a problem, and completes the polymerization reaction in a short time without using a chopped strand to prevent cracks! /, Fiber reinforced resin molding It is an object of the present invention to provide an apparatus for manufacturing a fiber-reinforced resin molded body for easily manufacturing a body, and a method for manufacturing the same. Disclosure of the invention
上記した目的を達成するために、本発明にかかる繊維強化樹脂成形体の製造装置 は、 成形型が回転自 に軸支されるとともに、 光照射装置が設けられた成形部と、 複数個の補強繊維の口ール体が配列され、各補強繊維ロール体からそれぞれ引き出 された補強繊維群を下流側に導く補強繊維集積部と、光重合開始剤を含む重合性樹 脂組成物が貯留された含浸槽を備え、一方の捕強繊維群に重合性樹脂組成物を含浸 させる含浸装置とともに、他方の捕強繊維群の各捕強繊維を、重合性樹脂組成物が 含浸されて回転する成形型に巻き取られる一方の捕強繊維群上にそれぞれランダ ,ムに蛇行するように供給するフイラメントワインディング供給装置が設けられた 補強繊維供給部と、から構成され、重合性樹脂組成物が含浸された一方の補強繊維 群上にランダムに蛇行した他方の補強繊維群を積層した状態の補強繊維群が回転 する成形型に巻き取られる.とともに、成形型に巻き取られた補強繊維群に光照射装 置を介して光が照射されて重合性樹脂組成物が硬化されることを特徴とする。  In order to achieve the above object, an apparatus for manufacturing a fiber-reinforced resin molded product according to the present invention includes a molding die that is supported by a rotating shaft, a molding section provided with a light irradiation device, and a plurality of reinforcing members. A reinforced polyester fiber composition containing a photopolymerization initiator and a reinforcing fiber accumulating portion that arranges a reinforcing fiber group drawn out from each reinforcing fiber roll body on the downstream side in which a fiber bundle is arranged are stored. With an impregnating tank for impregnating the polymerizable resin composition into one of the reinforcing fiber groups and rotating the impregnating fibers of the other reinforcing fiber group by impregnating the polymerizable resin composition. And a reinforcing fiber supply unit provided with a filament winding supply device for supplying a meandering land and a meandering fiber group on one of the strong fiber groups to be wound into a mold, respectively, and impregnated with the polymerizable resin composition. Other reinforcing fiber The reinforcing fiber group in a state where the other reinforcing fiber group meandering at random on the group is laminated is wound up by a rotating molding die, and the reinforcing fiber group wound up by the molding die is irradiated via a light irradiation device. It is characterized in that the polymerizable resin composition is cured by irradiation with light.
本発明によれば、補強繊維集積部に配置された各口一ル体の補強繊維の一半部は、 一方の補強繊維群として、含浸装置を経て重合性樹脂組成物を含浸されて引き出さ れ、 回転する成形型に卷き取られる。 また、補強繊維の他半部は、 他方の補強繊維 群として、 フィラメントワインデイング供給装置まで引き出され、 フィラメントヮ インディング供給装置によって繰り出される。また、他方の補強繊維群を成形型に 巻き取られる一方の補強繊維群に向けて供給すれば、他方の補強繊維群は、 ランダ ムに蛇行しながら一方の補強繊維群上に載置されるとともに、重合性樹脂組成物が 含浸された一方の捕強繊維群に粘着されてランダムに蛇行した状態に保持される。 したがって、回転する成形型には、童合性樹脂組成物が含浸された一方の補強繊維 群上にランダムに蛇行して粘着された他方の補強繊維群を積層した状態の補強繊 維群が巻き取られる。このようにして成形型に補強繊維群が巻き取られて一定の厚 みに到達すれば、含浸装置による一方の捕強繊維群の重合性樹脂組成物の含浸を停 止するとともに、 フィラメントワインディング供給装置を停止させ、 さらに、成形 型の回転を停止した後、一方の捕強繊維群および他方の補強繊維群を切断する。次 いで、成形型を回転させるとともに、光照射装置を介して光を照射すると、成形型 に積層された捕強繊維群に含浸された重合性樹脂組成物には、光重合開始剤が配合 されているため、光を受けて硬化を開始する。 そして、一定時間にわたって光を照 射することにより、重合性樹脂組成物が硬ィ匕して繊維強化樹脂パイプが製造された ならば、光照射を停止させるとともに、成形型の回転を停止させ、製造された繊維 強化樹脂パイプを取り出す。 According to the present invention, one-half of the reinforcing fibers of each of the plugs arranged in the reinforcing fiber accumulating portion are impregnated with the polymerizable resin composition through an impregnation device and pulled out as one of the reinforcing fiber groups, It is wound on a rotating mold. Further, the other half of the reinforcing fiber is drawn out to the filament winding supply device as the other reinforcing fiber group, and is fed out by the filament-inding supply device. Also, if the other reinforcing fiber group is supplied toward one reinforcing fiber group that is wound into a molding die, the other reinforcing fiber group is placed on one reinforcing fiber group while meandering at random. At the same time, it is adhered to one of the force-absorbing fibers impregnated with the polymerizable resin composition, and is maintained in a meandering state at random. Therefore, the rotating molding die has a reinforcing fiber in a state in which one reinforcing fiber group impregnated with a random resin composition is impregnated on the other reinforcing fiber group impregnated with the resin composition. The fibers are wound up. When the reinforcing fiber group is wound up to a certain thickness in the molding die in this way, impregnation of the polymerizable resin composition of one of the reinforcing fiber groups by the impregnating device is stopped, and filament winding is supplied. After stopping the apparatus and further stopping the rotation of the mold, one of the reinforcing fiber groups and the other reinforcing fiber group are cut. Next, when the mold is rotated and light is irradiated through a light irradiation device, a photopolymerization initiator is blended with the polymerizable resin composition impregnated in the reinforcing fiber group laminated on the mold. Therefore, it starts curing by receiving light. Then, by irradiating light for a certain period of time, if the polymerizable resin composition is hardened to produce a fiber-reinforced resin pipe, the light irradiation is stopped, and the rotation of the mold is stopped. Take out the manufactured fiber reinforced resin pipe.
この結果、製造された繊維強化樹脂成形体は、その周方向に一方の補強繊維群が 積層され、その軸線方向には、ランダムに蛇行した他方の補強繊維群が積層される ことになり、一方の補強繊維群の補強繊維と、他方の補強繊維群の捕強繊維が集中 する箇所は発生せず、 クラックの発生を確実に防止することができる。  As a result, in the manufactured fiber-reinforced resin molded body, one reinforcing fiber group is laminated in the circumferential direction, and the other randomly meandering reinforcing fiber group is laminated in the axial direction. A portion where the reinforcing fibers of the reinforcing fiber group and the reinforcing fibers of the other reinforcing fiber group concentrate does not occur, and the generation of cracks can be reliably prevented.
また、重合性樹脂組成物に光重合開始剤を配合していることにより、光を照射す れば、速やかに硬化が開始されるため、繊維強化樹脂パイプを短時間に製造するこ とが可能となり、作業効率を向上させることができる。 また、光を照射しなければ 硬化が開始されないことから、余剰の重合性樹脂組成物を回収して再利用を図るこ とができる。  In addition, by incorporating a photopolymerization initiator into the polymerizable resin composition, curing can be started promptly by irradiating light, so that fiber-reinforced resin pipes can be manufactured in a short time. And work efficiency can be improved. Further, since curing does not start unless light is irradiated, excess polymerizable resin composition can be recovered and reused.
上記構成において、含浸装置に、一方の補強繊維群の巻き取り方向の下流側に位 置して櫛状のガイド部材が設けられてもよい。  In the above configuration, the impregnating device may be provided with a comb-shaped guide member located downstream of the one reinforcing fiber group in the winding direction.
この場合、重合性樹脂組成物が含浸された一方の補強繊維群における各捕強繊維 が櫛状のガイド部材の各歯間を通過することにより、それらの補強繊維の間隔を保 持して下流側に導くことができる。 このため、一方の補強繊維群の補強繊維同士が 重合性樹脂組成物によつて束状に粘着して空隙が発生し、一方の補強繊維群上に供 給される他方の捕強繊維群が空隙から脱落するのを確実に防止することができる。 上記構成において、フィラメントワインディング供給装置から供給される他方の 捕強繊維群の単位時間あたりの長さが、成形型に卷き取られる一方の捕強繊維群の 単位時間あたりの長さよりも大きくてもよい。 In this case, each of the reinforcing fibers in one of the reinforcing fiber groups impregnated with the polymerizable resin composition passes between the teeth of the comb-shaped guide member, thereby maintaining the interval between the reinforcing fibers and downstream. Can be guided to the side. For this reason, the reinforcing fibers of one reinforcing fiber group adhere to each other in a bundle by the polymerizable resin composition to form a void, and the other reinforcing fiber group supplied on one reinforcing fiber group becomes Dropping from the gap can be reliably prevented. In the above configuration, the length per unit time of the other forcing fiber group supplied from the filament winding supply device is larger than the length per unit time of the forcing fiber group wound on the forming die. Is also good.
この場合、成形型に巻き取られる一方の補強繊維群上に他方の捕強繊維群を供給 するとき、他方の補強繊維群における各補強繊維は、その速度の速い分だけ一方の 補強繊維群上で弛むことになり、前後左右方向にランダムに蛇行しながら載置され る。 し力も、一方の補強繊維群に重合性樹脂組成物が含浸されているため、他方の 補強繊維群の各補強繊維は、一方の捕強繊維群に粘着されてランダムに蛇行した状 態に保持される。  In this case, when the other reinforcing fiber group is supplied onto the one reinforcing fiber group wound on the forming die, each reinforcing fiber in the other reinforcing fiber group is placed on one reinforcing fiber group by an amount corresponding to a higher speed. And it is placed while meandering randomly in the front, rear, left and right directions. Since the polymerizable resin composition is impregnated in one of the reinforcing fiber groups, each reinforcing fiber of the other reinforcing fiber group is adhered to the one of the reinforcing fiber groups and held in a randomly meandering state. Is done.
上記構成において、フィラメントワインディング供給装置に、他方の補強繊維群 の供給方向の下流側に位置して他方の補強繊維群の幅方向のはみだしを規制する ガイド板が設けられてもよい。  In the above configuration, the filament winding supply device may be provided with a guide plate that is located downstream of the other reinforcing fiber group in the supply direction and that controls the protrusion of the other reinforcing fiber group in the width direction.
この場合、他方の補強繊維群が、重合性樹脂組成物が含浸されて成形型に巻き取 られる一方の補強繊維群の幅を越えて逸脱するのを規制することができ、一方の捕 ^繊維群に他方の補強繊維群の各補強繊維を脱落させることなく確実に載置する ことができる。  In this case, it is possible to restrict the other reinforcing fiber group from deviating beyond the width of the one reinforcing fiber group impregnated with the polymerizable resin composition and wound on the molding die. Each reinforcing fiber of the other reinforcing fiber group can be reliably placed on the group without falling off.
上記構成において、成形部に、成形型の外周面に光を照射可能な捕助光照射装置 が設けられてもよい。  In the above configuration, the forming unit may be provided with a catching light irradiation device capable of irradiating the outer peripheral surface of the forming die with light.
この場合、後になるほど補強繊維が厚く積層されて光が透過しにくく、硬化しに くくなるような箇所においては、重合性樹脂組成物を含浸した一方の補強繊維群が 成形型に卷き取られて積層きれる際、硬ィヒしにくい箇所に光を照射することができ る。 また、繊維強化樹脂パイプが第 1 2図のような異なる断面 （肉厚が軸方向で変 化する場合） を有する場合には、特に集中的に光を透過させることができるため有 効である。 このため、一方の補強繊維群の卷き取り開始段階で重合性樹脂組成物を 硬化させることができ、硬化しにくい箇所が未硬化のまま繊維強ィヒ樹脂パイプが製 造されるのを防止することができる。 また、 この場合、捕助光照射装置としては、安全性の観点から、 紫外線を含むも のの、 可視光リッチとなっていることが好ましい。 In this case, one of the reinforcing fiber groups impregnated with the polymerizable resin composition is wound into a molding die in a portion where the reinforcing fibers are stacked thicker at a later time and light hardly transmits and hardly hardens. When lamination is completed, it is possible to irradiate light to hardly hard portions. Also, when the fiber reinforced resin pipe has a different cross section as shown in FIG. 12 (when the thickness changes in the axial direction), it is particularly effective because light can be transmitted intensively. . For this reason, the polymerizable resin composition can be cured at the stage of starting to wind up one of the reinforcing fiber groups, thereby preventing the production of a fiber-reinforced resin pipe without hardening the hard-to-harden portions. can do. In this case, the assisting light irradiating device preferably includes ultraviolet rays but is rich in visible light from the viewpoint of safety.
上記構成において、 成形型が型開き、 型閉め可能であってもよい。  In the above configuration, the mold may be opened and closed.
この場合、型閉めすることにより、製造された繊維強化樹脂パイプを成形型から 簡単に取り出すことができるため、好ましい。 これは、繊維強化榭脂パイプが場所 によって異なる断面を有する場合に、特に効果を発揮する。すなわち、強引に型を 引き抜く必要がないため、得られる繊維強化樹脂パイプに損傷を与えることなく脱 型することができる。  In this case, closing the mold is preferable because the manufactured fiber-reinforced resin pipe can be easily taken out of the molding die. This is particularly effective when the fiber-reinforced resin pipe has a different cross section from place to place. That is, since it is not necessary to forcibly pull out the mold, it is possible to remove the mold without damaging the obtained fiber-reinforced resin pipe.
上記構成において、光照射装置が、成形型の外周面に対向する照射位置と退避位 置間を進退自在であってもよい。  In the above configuration, the light irradiation device may be capable of moving forward and backward between the irradiation position facing the outer peripheral surface of the mold and the retracted position.
この場合、光照射装置を退避位置に移動させることにより、成形型を回転させて 補強繊維群を巻き取る際、成形型と光照射装置との干渉を防止することができると ともに、製造された繊維強化樹脂パイプを取.り出す際、円滑に作業することができ る。  In this case, by moving the light irradiating device to the retracted position, it is possible to prevent interference between the mold and the light irradiating device when rotating the forming die and winding up the reinforcing fiber group, and manufacturing When taking out the fiber reinforced resin pipe, it can work smoothly.
上記構成において、補強繊維供給部が、成形型に接近する作業位置と、離隔した 退避位置間を往復移動可能であってもよい。  In the above configuration, the reinforcing fiber supply unit may be capable of reciprocating between a working position approaching the mold and a separated retreat position.
この場合、補強繊維供給部を前進させて、回転する成形型に補強繊維群を卷き取 つて一定厚み積層することができ、一方、成形型に一定厚み積層された補強繊維群 に光を照射して含浸された重合性榭脂組成物を硬化させる際、光照射装置の邪魔に ' ならないように捕強繊維供給部を後退させることができる。また、直径の異なる繊 維強化樹脂パイプに対してそれぞれ補強繊維供給部の作業位置を決め'ることがで き、 1台の製造装置によつて各種直径の繊維強化樹脂パイプを製造することができ る。  In this case, the reinforcing fiber supply unit is advanced, and the reinforcing fiber group can be wound around the rotating mold and laminated with a certain thickness, while the reinforcing fiber group laminated with a certain thickness on the mold is irradiated with light. When the impregnated polymerizable resin composition is cured, the reinforcing fiber supply section can be retracted so as not to interfere with the light irradiation device. In addition, it is possible to determine the working position of the reinforcing fiber supply section for fiber reinforced resin pipes having different diameters, and it is possible to manufacture fiber reinforced resin pipes of various diameters with one manufacturing apparatus. it can.
上記構成において、成形型の下方に位置して重合性樹脂組成物を回収するトレー が設置され、 その流出開口にフィルターが設けられてもよい。  In the above configuration, a tray located below the mold for collecting the polymerizable resin composition may be provided, and a filter may be provided at the outflow opening.
この場合、成形型を回転して重合性樹脂組成物が含浸された補強繊維群を積層す る際、滴下する重合性樹脂組成物とともに、余剰に含浸された重合性榭脂組成物を 押し出して、 滴下する余剰の重合性樹脂糸且成物をトレーに回収することができる。 すなわち、重合性樹脂組成物は、未だ光が照射されていないため、硬化は開始され ておらず、再利用が可能である。 このため、重合性樹脂組成物の可使時間が長くな る。 また、 トレーにフィルターが設けられているため、 ゴミなどが混入することを 防止することができる。 In this case, the mold is rotated to laminate the reinforcing fiber group impregnated with the polymerizable resin composition. In this case, the excessively impregnated polymerizable resin composition is extruded together with the polymerizable resin composition to be dropped, and the excess polymerizable resin thread to be dropped can be collected in a tray. That is, since the polymerizable resin composition has not been irradiated with light yet, curing has not been started and the polymerizable resin composition can be reused. Therefore, the pot life of the polymerizable resin composition is prolonged. Further, since the filter is provided on the tray, it is possible to prevent dust and the like from being mixed.
さらに、上記構成において、記重合性樹脂組成物は、 高温反応型重合開始剤が配 合されたものであってもよい。  Further, in the above configuration, the polymerizable resin composition may be one in which a high-temperature reaction-type polymerization initiator is combined.

Can be selected as appropriate. Although not particularly limited, those which start the reaction at 50 ° C or higher are preferred. Specifically, the reaction started? As a polymerization initiator having a temperature of 50 to 100 ° C., t-butyl peroxetyl hexate, bis (4-t / l-butyl / hexyl hexyl) -peroxydicarbonate, 1, 1-bis (t-butylperoxy) 1,3,3,5-trimethylcyclohexane, t-butynolepoxy 2-ethylhexanate, diarboxoxide, reaction start temperature 100 ° C to 160 ° C Examples of the polymerization initiator include t-butyl peroxybenzoate, dicumyl peroxide, and the like.

Therefore, the polymerizable resin composition 6A dropped from one of the reinforcing fiber groups FA impregnated with the polymerizable resin composition 6A can be collected and led to the toy 9. In this case, the length of the gutter 0 is set according to the advance / retreat distance of the supply frame 5.
含浸装置 6は、第 8図に詳細に示すように、供給フレーム 5のフレーム本体 5 2 に固定され、光重合開始剤が配合された重合性樹脂組成物 6 Aを貯留する含浸槽 6 1と、含浸槽 6 1の前後各端部上方にそれぞれ一対ずつ設けられたガイドローラ 6 2と、 フレーム本体 5 2に固定された昇降シリンダ 6 3 (第 1図参照） と、 昇降シ. リンダ 6 3のピストンロッドに固定され、図示しないガイドに洽つて昇降自在な力 バー 6 4と、 力パー 6 4に垂設された一対の含浸ローラ 6 5と、 カゝらなり、 昇降シ リンダ 6 3を伸長作動させることにより、左右各一対のガイドローラ 6 2間におい て、カバー 6 4を介して一対の含浸ローラ 6 5を下降させ、左右各一対のガイドロ ーラ 6 2間を通過する一方の捕強繊維群 F Aを含浸槽 6 1に貯留された重合性樹 月旨組成物 6 Aに浸漬させることができる。 （ As shown in detail in FIG. 8, the impregnating device 6 is fixed to the frame main body 5 2 of the supply frame 5 and has an impregnating tank 61 for storing a polymerizable resin composition 6 A containing a photopolymerization initiator. , A pair of guide rollers 62 provided above the front and rear ends of the impregnation tank 61, a lifting cylinder 63 fixed to the frame body 52 (see Fig. 1), and a lifting cylinder 63 A force bar 64 fixed to the piston rod and movable up and down by a guide (not shown), a pair of impregnated rollers 65 suspended from the force par 64, and a lifting cylinder 63 By performing the extension operation, the pair of impregnating rollers 65 is lowered through the cover 64 between the pair of left and right guide rollers 62, and the pair of left and right guide rollers One of the strong fiber groups FA passing between the rollers 62 can be immersed in the polymerizable luster composition 6A stored in the impregnation tank 61. (
さらに、含浸槽 6 1には、前方のガイドローラ 6 2の下流側に位置して櫛状のガ ィド部材 6 6が設けられている。 このガイド部材 6 6は、重合性榭脂組成物 6 Aが 含浸されて前方に導かれた一方の補強繊維群 F Aの各補強繊維 Fが重合性樹脂組 成物 6 Aを介して付着し、束状となることによつて一方の捕強繊維群 F Aに空隙が 生じるのを防止している。すなわち、後述するように、他方の補強繊維群 F Cを一 方の補強繊維群 F A上に供給するとき、一方の補強繊維群 F Aに形成された空隙を 通して他方の補強繊維群 F Cの各捕強繊維 Fが地上に落下するのを防止する。  Further, the impregnation tank 61 is provided with a comb-shaped guide member 66 located on the downstream side of the front guide roller 62. The guide member 66 is impregnated with the polymerizable resin composition 6A, and each reinforcing fiber F of one of the reinforcing fiber groups FA guided forward adheres through the polymerizable resin composition 6A, The formation of a bundle prevents the formation of voids in one of the reinforcing fiber groups FA. That is, as described later, when the other reinforcing fiber group FC is supplied onto one reinforcing fiber group FA, each trapping of the other reinforcing fiber group FC is performed through a gap formed in one reinforcing fiber group FA. Prevents strong fiber F from falling to the ground.
なお、後方のガイドローラ 6 2の上流側に位置して、前述しチこ補強繊維集積部 1 Bから引き出された一方の捕強繊維群 F Aの各補強強繊 Fを方向を変えて、ほぼ水 平にガイドローラ 6 2に導くため、各補強繊維 Fを揷通させる多数の穴が形成され たガイド 6 7が設けられている。  In addition, it is located on the upstream side of the rear guide roller 62, and changes the direction of each reinforcing fiber F of one of the reinforcing fiber groups FA drawn out from the above-described reinforcing fiber accumulating portion 1B.

At this time, make sure to pass between the supply roller 74 and the auxiliary roller 74. The other group of reinforcing fibers FC guided by this can be supplied toward the front. Here, the rotation speed of the supply roller 74, that is, the supply length of the other reinforcing fiber group FC per unit time is determined by the peripheral speed of the molding die 2, that is, the one reinforcing fiber per unit time. It is set slightly larger than the winding length of group FA. For this reason, as described later, when the other reinforcing fiber group FC is supplied onto one of the reinforcing fiber groups FC which is drawn and wound on the molding die 2, each reinforcing fiber in the other reinforcing fiber group FC is supplied. The fiber F is slackened on one of the forcing fiber groups FA by an amount corresponding to the higher speed, and is placed on one of the forcing fiber groups FA while meandering randomly in the front-rear and left-right directions (No. 11). See figure). '

次いで、含浸装置 6まで引き出された一方の捕強繊維群 F Aを図示しな 、治具に 結束した後、治具を成形型 2に係止して成形型 2を若干回転させ、一方の捕強繊維 群 F Aを成形型 2の外周面に略 1周ほど巻き付ける。 この際、詳細には図示しない 力 成形型 2の外周面に巻き付けられた一方の捕強繊維群 F Aに重合性樹脂組成物 Next, one of the reinforcing fiber groups FA drawn out to the impregnating device 6 is not shown, but after being bound to a jig, the jig is locked to the forming die 2 and the forming die 2 is slightly rotated, so that one of the collecting fibers The strong fiber group FA is wound around the outer peripheral surface of the mold 2 approximately one round. At this time, the polymerizable resin composition is applied to one of the force-absorbing fiber groups FA wound around the outer peripheral surface of the force forming mold 2 (not shown in detail).
6 Aを塗布し、成形型 2に粘着させる。 また、 ハンドル 7 3 1を回転操作して昇降 フレーム 7 2を昇降させ、供給ローラ 7 4および補助ローラ 7 4 1の高さを調整す る。合わせて、押圧ローラ装置 8の電動モータ 8 6を駆動させ、押圧ローラ 8 5が 成形型 2の外周面に接するように、 高さを調整する。 6 A is applied and adhered to the mold 2. In addition, the handle 731 is rotated to raise and lower the lifting frame 72, and adjust the height of the supply roller 74 and the auxiliary roller 741. At the same time, the electric motor 86 of the pressing roller device 8 is driven, and the height is adjusted so that the pressing roller 85 contacts the outer peripheral surface of the molding die 2.
さらに、補助光照射装置 3 6を照射位置に回動させ、成形型 2の外周面に対向さ せる。 また、含浸装置 6の昇降シリンダ 6 3を伸長作動させ、押圧ローラ 6 5を含 浸槽 6 1の内部に進入させ、前後各一対ずつのガイドローラ 6 2間にわたって引き 出された一方の補強繊維群 F Aを含浸槽 6 1の重合性樹脂組成物 6 Aに浸漬させ る。 '  Further, the auxiliary light irradiation device 36 is rotated to the irradiation position so as to face the outer peripheral surface of the mold 2. Also, the lifting cylinder 63 of the impregnating device 6 is extended, the pressing roller 65 enters the inside of the impregnating tank 61, and one reinforcing fiber drawn out between the pair of front and rear guide rollers 62. The group FA is immersed in the polymerizable resin composition 6A in the impregnation tank 61. '
この後、図示しない治具を成形型 2から離脱させて成形型 2を回転させると、成 形型 2の外周面に粘着された一方の補強繊維群 F Aは、成形型 2の外周面に卷き取 られる。 この際、一方の補強繊維群 F Aは、含浸槽 6 1に貯留された重合性榭脂組 成物 6 A中を通過するため、重合性樹脂組成物 6 Aが含浸されて成形型 2に卷き取 られる。 ここで、捕助光照射装置 3 6のランプ 3 6 1を点灯すれば、 ゴム製リング W Thereafter, when the jig (not shown) is removed from the molding die 2 and the molding die 2 is rotated, one of the reinforcing fiber groups FA adhered to the outer peripheral surface of the molding die 2 is wound around the outer peripheral surface of the molding die 2. Will be taken away. At this time, one of the reinforcing fiber groups FA passes through the polymerizable resin composition 6A stored in the impregnation tank 61, so that the polymerizable resin composition 6A is impregnated and wound around the molding die 2. Will be taken away. Here, if the lamp 3 61 of the auxiliary light irradiation device 36 is turned on, the rubber ring W
22  twenty two
1 1の外側端面と、成形型 2の外周面と、 フランジ部材 2 1、 2 5の内端面とによ つて形成される A部分に光が照射され、この A部分に積層された一方の補強繊維群 F Aに含浸された重合性樹脂組成物 6 Aは光硬化する。  11 A portion formed by the outer end surface of 1, the outer peripheral surface of the mold 2 and the inner end surfaces of the flange members 21 and 25 is irradiated with light, and one of the reinforcements laminated on the A portion The polymerizable resin composition 6A impregnated in the fiber group FA is light-cured.
すなわち、 A部分に巻き付けられた一方の補強繊維群 F Aに含浸された重合性樹 脂組成物 6 Aは、当該部分の製品肉厚が厚いため、後になるほど一方の補強繊維群 F Aが積層されて光が透過しにくく、硬ィ匕しにくくなる。 したがって、重合性樹脂 組成物 6 Aを一方の補強繊維群 F Aの卷き取り開始段階で光硬化させることによ り、 A部分が未硬化のまま繊維強ィヒ樹脂パイプ 1 0が製造されるのを防止すること ができる。 ' '  That is, the polymerizable resin composition 6A impregnated in one of the reinforcing fiber groups FA wound around the part A has a thicker product thickness in the relevant part, so that one of the reinforcing fiber groups FA is laminated later. Light is less likely to pass through, and it is difficult to harden. Therefore, by fiber-curing the polymerizable resin composition 6A at the stage of starting the winding of one of the reinforcing fiber groups FA, the fiber-reinforced resin pipe 10 is manufactured with the part A uncured. Can be prevented. ''
この場合、捕助光照射装置 3 6のランプ 3 6 1は、紫外線を含むものの、可視光 リツチとなっているため、 安全性に問題はない。  In this case, although the lamp 36 1 of the assisting light irradiating device 36 contains ultraviolet rays, it has visible light, so there is no problem in safety.
このように、成形型 2の回転により、成形型 2の A部分に積層された一方の補強 繊維群 F Aに含浸された重合性樹脂組成物 6 Aが補助光照射装置 3 6によって光 硬ィ匕しつつ、重合性樹脂組成物 6 Aが含浸された一方の捕強繊維群 F Aが成形型 2 に卷き取られる。  As described above, by the rotation of the molding die 2, the polymerizable resin composition 6A impregnated in the one reinforcing fiber group FA laminated on the portion A of the molding die 2 is subjected to light curing by the auxiliary light irradiation device 36. Meanwhile, one of the reinforcing fiber groups FA impregnated with the polymerizable resin composition 6 A is wound up into the mold 2.
この状態で、 一方の補強繊維群 F Aを一定時間にわたって成形型 2に巻き付け、 成形型 2の外周面から突出するゴム製リング 1 1の高さとほぼ厚みだけ積層され たならば、いったん成形型 2の回転を停止し、補助光照射装置 3 6を退避位置に格 納する。 そして、再び成形型 2を回転させると同時に、 フィラメントワインディン, グ供給装置 7の電動モータ 7 5を駆動させることにより、供給ローラ Ί 4および補 助ローラ 7 4 1を回転させ、 他方の捕強繊維群 F Cを繰り出す。  In this state, one of the reinforcing fiber groups FA is wound around the molding die 2 for a certain period of time, and once the rubber ring 11 protruding from the outer peripheral surface of the molding die 2 is laminated by the height and almost the thickness, once the molding die 2 Is stopped, and the auxiliary light irradiation device 36 is stored at the retracted position. Then, by simultaneously rotating the molding die 2 again and simultaneously driving the electric motor 75 of the filament winding / feeding device 7, the supply roller # 4 and the auxiliary roller 741 are rotated, and the other capture force is applied. Feed out fiber group FC.
ここで、供給ローラ 7 4の回転速度、すなわち、単位時間当たりの他方の補強繊 維群 F Cの供給長さは、成形型 2の周速、すなわち、単位時間当たりの一方の補強 繊維群 F Aの卷き取り長さよりも若干大きく設定されていることから、成形型 2に 卷き取られる一方の補強繊維群 F A上に他方の補強繊維群 F Cを供給するとき、他 方の捕強繊維群 F Cにおける各補強繊維 Fは、その速度の速い分だけ一方の捕強繊 維群 F A上で弛むことになり、第 1 1図に示したように、前後左右方向にランダム に蛇行しながら载置される。 Here, the rotation speed of the supply roller 74, that is, the supply length of the other reinforcing fiber group FC per unit time is determined by the peripheral speed of the molding die 2, that is, the one reinforcing fiber group FA per unit time. Since the length is set slightly larger than the winding length, when the other reinforcing fiber group FC is supplied onto one reinforcing fiber group FA wound on the molding die 2, the other reinforcing fiber group FC is supplied. Of each reinforcing fiber F It will be slack on the fiber group FA and, as shown in Fig. 11, it will be placed while meandering randomly in the front, rear, left and right directions.
この際、一方の補強繊維群 F Aの捕強繊維 Fは、ガイド部材 6 6の各齒間を通過 して互いの間隔が維持されており、重合性樹脂組成物 6 Aによって束状に粘着して 空隙が発生するのを確実に防止している。 このため、各補強繊維 Fがほぼ一定の間 隔をおいて移動する一方の捕強繊維群 F Aに、他方の補強繊維群 F Cの各ネ翁強繊維 Fが確実に载置される。，  At this time, the reinforcing fibers F of one of the reinforcing fiber groups FA pass between the teeth of the guide member 66 and are maintained at an interval from each other, and are adhered in a bundle by the polymerizable resin composition 6A. This ensures that voids are not created. For this reason, one reinforcing fiber group F A in which each reinforcing fiber F moves at a substantially constant interval, and each of the reinforcing fiber groups F C in the other reinforcing fiber group F C is reliably disposed. ,
また、一方の補強繊維群 F Aの幅を越えて他方の補強繊維群 F Cの各捕強繊維 F が逸脱しようとしても、左右一対のガイド板 7 9によって規制されているため、確 実に一方の捕強繊維群 F A上に载置される。 しかも、一方の補強繊維群 F Aに重合 性樹脂組成物 6 Aが含浸されているため、他方の補強繊維群 F Cの各捕強繊維 Fは、 一方の捕強繊維群 F Aに粘着されてランダムに蛇行した状態に保持される。  Also, even if each of the reinforcing fibers F of the other reinforcing fiber group FC attempts to deviate beyond the width of one of the reinforcing fiber groups FA, since it is regulated by the pair of left and right guide plates 79, one of the reinforcing fibers F is surely removed. Located on the strong fiber group FA. In addition, since one of the reinforcing fiber groups FA is impregnated with the polymerizable resin composition 6A, each of the reinforcing fibers F of the other reinforcing fiber group FC is randomly adhered to the one of the reinforcing fiber groups FA. It is kept in a meandering state.
この結果、回転する成形型 2には、重合性樹脂組成物 6 Aが含浸された一方の補 強繊維群 F A上にランダムに蛇行して粘着された他方の補強繊維群 F Cを積層し た状態の補強繊維群が卷き取られる。 すなわち、 成形型 2の外周面の周方向には、 —方の捕強繊維群 F Aが積層され、その軸線方向には、 ランダムに蛇行した他方の 補強繊維群 F Cが積層され、一方の補強繊維群 F Aの補強繊維 Fと、他方の補強繊 維群 F Cの補強繊維 Fとが集中する箇所を発生することなく成形型 2に補強繊維 群が卷き取られる。  As a result, the rotating mold 2 has a state in which the other reinforcing fiber group FC, which is randomly meandered and adhered, is laminated on one reinforcing fiber group FA impregnated with the polymerizable resin composition 6A. Is wound up. That is, in the circumferential direction of the outer peripheral surface of the molding die 2, the negative reinforcing fiber group FA is laminated, and in the axial direction, the other reinforcing fiber group FC meandering at random is laminated, and one reinforcing fiber group FC is laminated. The reinforcing fiber group is wound around the mold 2 without generating a location where the reinforcing fiber F of the group FA and the reinforcing fiber F of the other reinforcing fiber group FC concentrate.
成形型 2に重合性樹脂組成物 6 Aが含浸された一方の捕強繊維群 F A上にラン ダムに蛇行して粘着された他方の補強繊維群 F Cを積層した状態の補強繊維群が 卷き取られて一定の厚みに到達すれば、昇降シリンダ 6 3を縮小作動させ、含浸口 ーラ 6 5を重合性樹脂組成物 6 Aから引き上げるとともに、フィラメントワインデ ィング供給装置 7の電動モータ 7 5の駆動を停止させる。 さらに、その状態で一定 長さ卷き取ったならば、成形型 2の回転を停止した後、一方の補強繊維群 F Aおよ ぴ他方の補強繊維群 F Cをフィラメントワインディング供給装置 7の下流側で切 断し、 供給フレーム 5を補強繊維集積部 1 B側に後退させる。 A reinforcing fiber group in a state where the other reinforcing fiber group FC meandering and sticking in a random manner on one of the reinforcing fiber groups FA in which the mold 2 is impregnated with the polymerizable resin composition 6 A is wound. When it is removed and reaches a certain thickness, the elevating cylinder 63 is contracted to raise the impregnation roller 65 from the polymerizable resin composition 6A, and the electric motor 75 of the filament winding supply device 7 Stop driving. Further, if a certain length is wound in this state, after the rotation of the molding die 2 is stopped, one of the reinforcing fiber groups FA and the other reinforcing fiber group FC are fed to the downstream side of the filament winding supply device 7. Off Then, the supply frame 5 is retracted to the reinforcing fiber accumulation section 1B side.
その後、成形型 2を再び回転させ、詳細には図示しないが、積層された補強繊維 群にローラを押し当て、積層された捕強繊維群に混入した空気を排出するとともに、 余剰に含浸された重合性樹脂組成物 6 Aを押し出す。押し出された余剰の重合性榭 脂組成物 6 Aは、成形型 2からトレ一 9に滴卞し、成形型 2の回転時に滴下した重 合性樹脂組成物 6 Aとともにフィルター 9 1を経て回収マス 9 2に回収された後、 回収ポンプ 9 3によって再ぴ含浸槽 7 1に回収される。すなわち、重合性樹脂組成 物 6 Aは、未だ光が照射されていないため、硬化は開始されておらず、再利用が可 能である。 このため、 重合性樹脂組成物 6 Aの可使時間が長くなる。  Thereafter, the molding die 2 was rotated again, and although not shown in detail, a roller was pressed against the laminated reinforcing fiber group to discharge air mixed in the laminated reinforcing fiber group, and excessively impregnated. Extrude 6 A of the polymerizable resin composition. Extruded excess polymerizable resin composition 6A is dropped from tray 2 onto tray 9 and collected through filter 91 together with polymer resin composition 6A dropped during rotation of mold 2. After being collected in the mass 92, it is collected in the regeneration impregnation tank 71 by the collection pump 93. That is, since the polymerizable resin composition 6A has not been irradiated with light yet, curing has not been started and the polymerizable resin composition 6A can be reused. Therefore, the pot life of the polymerizable resin composition 6A is prolonged.
この際、 トレー 9に設けられたフィルター 9 1により、 ゴミなどが混入すること が防止される。 これは、繊維強化樹脂パイプが異なる断面を有する場合に、 特に効 果を発揮する。すなわち、上記のような形状のパイプを成形する際には、光照射補 助ランプを使用することが好ましく、この補助ランプの卷回中の照射により余剰樹 脂のゲルィ匕が起こる可能性が高い。このゲルィ匕物が滴下樹脂とともにトレー 9に落 下し、 含浸槽 7 1に回収されてつまりなどの原因となるのを防止することができ、 また、回収樹脂内に混入するのも防止することができる。 この場合におけるフィル ター 9 1の網目の大きさとしては、 3〜4 O mmの間で選択するのが望ましい。 脱泡作業が終了すれば、光照射装置 3の図示しない電動モータを駆動させ、攆動 フレーム 3 2、すなわち、 ランプシェード 3 3を成形型 2の上方外周面に対向する 照射位置まで移動させるとともに、成形型 2の外周面までの間隔を調整する。そし て、製造装置 1の周囲に図示しない遮光カーテンを張りめぐらせた後、成形型 2を 回転させるとともに、 U Vランプ 3 4の光を照射させる。  At this time, dust and the like are prevented from being mixed in by the filter 91 provided on the tray 9. This is particularly effective when the fiber reinforced resin pipes have different cross sections. That is, when forming a pipe having the above-described shape, it is preferable to use a light irradiation auxiliary lamp, and irradiation during the winding of the auxiliary lamp is likely to cause excess resin gelling. . It is possible to prevent that the gelly dangling material falls into the tray 9 together with the dripped resin and is collected in the impregnation tank 71 to cause clogging and the like, and also prevented from being mixed into the collected resin. Can be. In this case, the size of the mesh of the filter 91 is desirably selected between 3 and 4 Omm. When the defoaming operation is completed, the electric motor (not shown) of the light irradiation device 3 is driven to move the driving frame 32, that is, the lamp shade 33, to the irradiation position facing the upper outer peripheral surface of the molding die 2, and Adjust the distance to the outer peripheral surface of the mold 2. Then, after a light-shielding curtain (not shown) is stretched around the manufacturing apparatus 1, the mold 2 is rotated and the light of the UV lamp 34 is irradiated.
この際、成形型 2に積層された捕強繊維群に含浸された重合性樹脂組成物 6 Aに は、光重合開始剤が配合されているため、 UVランプ 3 4からの紫外線リツチの光 を受けて硬化を開始する。そして、一定時間 U Vランプ 3 4.の光を照射することに より、重合性樹脂組成物 6 Aが硬ィ匕したならば、すなわち、繊維強化樹脂パイプ 1 0が製造されたならば、 U Vランプ 3 4の光の照射を中止し、退避位置に移動させ るとともに、成形型 2の回転を停止する。合わせて、遮光カーテンを元の位置に戻 す。 At this time, since the photopolymerization initiator is mixed in the polymerizable resin composition 6 A impregnated in the reinforcing fiber group laminated on the molding die 2, the light from the ultraviolet lamp 34 from the UV lamp 34 is irradiated. Receiving starts curing. Then, if the polymerizable resin composition 6A is hardened by irradiating the light of the UV lamp 34 for a certain period of time, that is, the fiber-reinforced resin pipe 1 When 0 is manufactured, the irradiation of the light from the UV lamps 34 is stopped, and the mold is moved to the retracted position and the rotation of the mold 2 is stopped. At the same time, return the blackout curtain to its original position.
次いで、前述とは逆に、成形型 2を型閉めした後、 フランジ部材 2 5を固定金型 2 2力、ら離脱させる。そして、製造された繊維強化樹脂パイプ 1 0の周囲にパンド などを掛け回して天井クレーンなどによって吊り上げ、 次の工程に移動させる。 . このようにして製造された繊維強化樹脂パイプ 1 0は、その周方向には、一方の 補強繊維群 F Aが積層され、その軸線方向には、 ランダムに蛇行した他方の補強繊 維群 F Cが積層されることになり、一方の補強繊維群 F Aの補強繊維 Fと、他方の 補強繊維群 F Cの補強繊維 Fが集中する箇所は発生せず、クラックの発生を確実に P力止することができる。  Next, contrary to the above, after closing the mold 2, the flange member 25 is released from the fixed mold 22. Then, a band or the like is wrapped around the manufactured fiber-reinforced resin pipe 10, lifted by an overhead crane or the like, and moved to the next step. In the fiber reinforced resin pipe 10 manufactured in this manner, one reinforcing fiber group FA is laminated in the circumferential direction, and the other reinforcing fiber group FC meandering randomly in the axial direction. As a result, there is no place where the reinforcing fiber F of one reinforcing fiber group FA and the reinforcing fiber F of the other reinforcing fiber group FC concentrate, and the generation of cracks can be securely stopped by the P force. it can.
また、重合性樹脂組成物 6 Aに光重合開始剤を配合していることにより、光を照 射すれば、速やかに硬化が開始されるため、繊維強化樹脂パイプ 1 0を短時間に製 造することが可能となり、作業効率を向上させることができる。 また、光を照射し なければ硬ィヒが開始されないことから、余剰の重合性樹脂組成物 6 Aを回収して再 利用を図ることができる。  In addition, since the photopolymerization initiator is blended with the polymerizable resin composition 6A, curing can be started promptly by irradiating light, so that the fiber reinforced resin pipe 10 can be manufactured in a short time. Work efficiency can be improved. In addition, since the hard coating is not started unless light is irradiated, the excess polymerizable resin composition 6A can be recovered and reused.
なお、 '前述した実施形態においては、一方の補強繊維群 F Aを成形型 2に直接卷 き取る場合を説明したが、成形型 2の外周面との離型性を考慮して、繊維強化樹脂 パイプ 1 0の製造に先立って、成形型 2の外周面に離型フィルムを卷き付けてから 作業を開始することが好ましい。 ，  In the above-described embodiment, the case where one reinforcing fiber group FA is directly wound on the molding die 2 has been described. However, in consideration of the releasability from the outer peripheral surface of the molding die 2, the fiber-reinforced resin It is preferable to start the operation after winding a release film around the outer peripheral surface of the mold 2 before manufacturing the pipe 10. ,
次に、本実施の形態 1にかかる繊維強化樹脂パイプ 1 0の製造装置 1、およびそ の製造方法とは異なる他の繊維強化樹脂パイプの製造装置、およびその製造方法に ついて説明する。 なお、本実施の形態 1にかかる繊維強化樹脂パイプ 1 0の製造装 置 1の構成部材と同一名称の構成部材には、 同一の符号を付す。  Next, an apparatus 1 for manufacturing the fiber-reinforced resin pipe 10 according to the first embodiment, an apparatus for manufacturing another fiber-reinforced resin pipe different from the method for manufacturing the same, and a method for manufacturing the same will be described.

この製造装置 1は、第 1 3図に示すように、成形部 1 Aと、成形部 1 Aから離隔 して設置された補強繊維集積部 1 Bと、成形部 1 Aと補強繊維集積部 1 Bとの間に 配設された補強 維供給部 1 Cと、 から構成,されている。  As shown in FIG. 13, the manufacturing apparatus 1 includes a forming section 1A, a reinforcing fiber collecting section 1B provided separately from the forming section 1A, a forming section 1A and the reinforcing fiber collecting section 1A. And a reinforcing fiber supply unit 1C, which is provided between the two.
成形部 1 Aは.、回転自在に軸支されたドラム状からなる芯型の成形型 2と、下記 する補強繊維 Fに付着された重合性樹脂組成物 6 Aを硬化させるために下記する 光重合開始剤が反応を開始する波長の光を照射する光照射装置 3と、重合性樹脂組 成物 6 Aを嘖霧または滴下するノズル 1 0と、から構成され、補強繊維 Fが成形型 2の外周面に所定周回数巻き付けられて、 パイプ状に賦形される。  The molding part 1A is a core-shaped molding die 2 having a drum shape rotatably supported on a shaft and a polymerizable resin composition 6A attached to a reinforcing fiber F described below.

光照射装置 3には、第 1 4図に示すよ に、 シャッター 3 7が設けられ、 このシ ャッター 3 7を開閉することにより、ランプ 3 4の光が成形型 2に巻き付けられた 補強繊維 Fに向けて照射される構成となっている。 また、 この光照射装置 3には、 図示しない送風機に接続された送気管 3 8 1および排気管 3 8 2と、ランプ 3 4か らの光の照射量を制御するための熱線フィルタ 3 9とが設けられている。  As shown in FIG. 14, the light irradiation device 3 is provided with a shutter 37, and by opening and closing the shutter 37, the light of the lamp 34 is reinforced by the reinforcing fiber F wound around the mold 2. Irradiated toward. The light irradiation device 3 includes an air supply pipe 38 1 and an exhaust pipe 38 2 connected to a blower (not shown), and a heat ray filter 39 for controlling the amount of light emitted from the lamp 34. Is provided.
また、成形部 1 Aには、成形型 2の下方側外周面に対向して重合性榭脂組成物（光 重合開始剤を む重合性樹脂組成物 6 A) を回収するトレイ 9が配設されており、 このトレィ 9に回収された重合性樹脂組成物 6 Aは、回収ポンプ 9 3を介して後述 する含浸装置 （図示省略） の含浸槽 6 1に回収される。  In addition, a tray 9 for collecting the polymerizable resin composition (polymerizable resin composition 6A containing a photopolymerization initiator) is provided in the molding portion 1A so as to face the lower outer peripheral surface of the molding die 2. The polymerizable resin composition 6A collected in the tray 9 is collected in an impregnation tank 61 of an impregnation device (not shown) described later via a collection pump 93.
補強繊維集積部 1 Bは、ガラスロービングなどの補強繊維 Fの口ール体 Rを複数 個配列して構成されている。そして、各ロール体 Rからそれぞれ引き出された補強 繊維 Fは、引き揃えられた状態で二分され、その一半部が後述する補強繊維供給部 1 Cの含浸装置（第 1 3図の含浸槽 6 1参照） に、 その他半部が補強繊維供給部 1 Cのフィラメントワインデイング供給装置（図示省略、第 1 3図の供給ローラ 7 4 参照） にそれぞれ導かれる。 なお、含浸装置に導かれた補強繊維群を、一方の補強 繊維群と記載して符号 F Aを用い、また、 フィラメントワインデイング供給装置に 導かれた捕強繊維群を、他方の捕強繊維群と記載して符号 F Cを用いるものとする (第 1 3図参照)。 The reinforcing fiber accumulating portion 1B is configured by arranging a plurality of jaws R of reinforcing fibers F such as glass roving. The reinforcing fibers F drawn out from the respective rolls R are divided into two in a aligned state, and one half of the reinforcing fibers F is impregnated with the impregnating device (impregnating tank 6 1 in FIG. The other half is guided to a filament winding supply device (not shown, see supply roller 74 in FIG. 13) of reinforcing fiber supply section 1C. The reinforcing fiber group guided to the impregnating device is referred to as one reinforcing fiber group and the symbol FA is used, and the reinforcing fiber group guided to the filament winding supply device is used as the other reinforcing fiber group. And use the code FC (See Figure 13).
なお、補強繊維供給部 1 Cの含浸装置に導く複数個の捕強繊維 Fの口ール体 Rと、 フィラメントワインディング供給装置に導く補強繊維 Fの口ール体 Rとを各装置 に合わせて個別に配置し、 各装置に供給するようにしてもよい。 、  In addition, the mullet R of the plurality of reinforcing fibers F guided to the impregnating device of the reinforcing fiber supply unit 1C and the mullet R of the reinforcing fiber F guided to the filament winding supply device are matched to each device. You may arrange | position individually and supply it to each apparatus. ,
補強繊維供給部 1 .Cは、光重合開始剤が配合された重合性樹脂組成物 6 Aを貯留 する含浸装置と、補強繊維集積部 1 Bから引き出された他方の補強繊維群 F Cの送 り出し方向を変えるフィラメントワインデイング供給装置と、から構成され、一方 の補強繊維群 F Aが含浸装置に貯留された重合性樹脂組成物 6 Aに浸漬され、この 浸漬された.一方の補強繊維群 F Aにフィラメントワインディング供給装置から送 り出された他方の補強繊維群 F Cが粘着される。この他方の補強繊維群 F Cの粘着 により、補強繊維群 Fが束状となり、一方の補強繊維群 F Aに空隙が生じるのを防 止している。すなわち、後述するように、他方の補強繊維群 F Cを一方の捕強繊維 群 F A上に供給するとき、一方の補強繊維群 F Aに形成された空隙を通して他方の 補強繊維群 F Cの各補強繊維 Fが地上に落下するのを防止する。  Reinforcing fiber supply section 1.C is provided with an impregnating device for storing polymerizable resin composition 6A containing a photopolymerization initiator, and feed of the other reinforcing fiber group FC drawn from reinforcing fiber accumulating section 1B. And a filament winding supply device for changing the feeding direction. The other reinforcing fiber group FC sent out from the filament winding supply device is adhered. The adhesion of the other reinforcing fiber group F C prevents the reinforcing fiber group F from becoming a bundle, thereby preventing a void from being generated in the one reinforcing fiber group F A. That is, as described later, when the other reinforcing fiber group FC is supplied onto the one reinforcing fiber group FA, each reinforcing fiber F of the other reinforcing fiber group FC passes through the void formed in the one reinforcing fiber group FA. To prevent it from falling to the ground.
フィラメントワインディング供給装置には、他方の捕強繊維群 F Cを送り出す供 給ローラ 7 4が設けられ、この供給ローラ 7 4による他方の補強繊維群 F Cを送り 出す送り出し速度は、ドラム状からなる成形型 2の回転速度よりも速く設定されて いる。すなわち、 フィラメントワインディング供給装置 7の単位時間当たりめ他方 の補強繊維群 F Cの供給長さは、成?^型 2の単位時間当たりの一方の補強繊維群 F Aの卷き取り長さよりも若干大きく設定されている。 このため、引き揃えられて成 形型 2に巻き取られる一方の補強繊維群 F A上に他方の補強繊維群 F Cを供給す るとき、他方の補強繊維群 F Cにおける各捕強 «隹 Fは、その速度の速い分だけ一 方の補強繊維群 F A上で弛むことになり、一方の補強繊維群 F A上に前後左右方向 にランダムに蛇行しながら载置される （第 1 1図参照）。 すなわち、 供給ローラ 7 4で送られる他方の補強繊維群 F Cは、成形型 2の回転速度よりも速く送りだされ ることにより、その卷き癖及び送り溜まりによって不規則なループ状あるいは蛇行 した状態で、含浸槽 6 1と成形型 2との間で一方の補強繊維群 F A上に連続的に供 給され、一方の補強繊維群 F Aとともに成形型 2への所定の厚みになるまで連続的 に巻き付けられる。 The filament winding supply device is provided with a supply roller 74 for feeding out the other reinforcing fiber group FC, and the feeding speed for sending out the other reinforcing fiber group FC by the supply roller 74 is a drum-shaped forming die. The rotation speed is set faster than 2. That is, the supply length of the other reinforcing fiber group FC per unit time of the filament winding supply device 7 is set to be slightly larger than the winding length of one reinforcing fiber group FA per unit time of the mold 2. Have been. For this reason, when the other reinforcing fiber group FC is supplied onto one reinforcing fiber group FA that is aligned and wound into the molding die 2, each force «UF F in the other reinforcing fiber group FC is The higher the speed, the more slack it is on one of the reinforcing fiber groups FA, and it is placed on one of the reinforcing fiber groups FA while meandering randomly in the front-rear and left-right directions (see Fig. 11). That is, the other reinforcing fiber group FC sent by the supply roller 74 is sent out faster than the rotation speed of the molding die 2, and thus has an irregular loop or meandering due to its winding habit and feed pool. In this state, it is continuously supplied onto one of the reinforcing fiber groups FA between the impregnation tank 61 and the forming die 2 and continuously with the one reinforcing fiber group FA until the thickness of the forming die 2 reaches a predetermined value. It is wound around.
次に、 このように構成された繊維強化樹脂パイプ 1 0の製造工程について、第 1 3図を用いて以下に説明する。  Next, a manufacturing process of the fiber reinforced resin pipe 10 configured as described above will be described below with reference to FIG.
この製造方法は、補強繊維供給部 1 Cから引き出されて平行に引き揃えられた複 数の周方向長繊維捕強材としての一方の補強繊維群 F Aを光重合開始剤を含む重 合性樹脂組成物 6 Aが貯め れた含浸槽 6 1に連続的に通し、一方の補強繊維群 F Aに重合性樹脂組成物 6 Aを含浸させたのち、回転する成形型 2に所定周回数卷き 付ける。  In this manufacturing method, one reinforcing fiber group FA as a circumferential long fiber reinforcing material drawn out from the reinforcing fiber supply section 1C and aligned in parallel is used as a polymer resin containing a photopolymerization initiator. After continuously passing through the impregnation tank 6 1 in which the composition 6 A is stored and impregnating one of the reinforcing fiber groups FA with the polymerizable resin composition 6 A, it is wound around the rotating mold 2 a predetermined number of times. .
そして、補強繊維供給部 1 Cから引き出され、供給ローラ 7 4で送られる軸方向 長繊維補強材としての他方の補強繊維群 F Cは、成形型 2の回転速度よりも速く送 りだされることにより、その巻き癖及び送り溜まりによって不規則なループ状ある いは蛇行した状態で、含浸槽 6 1と成形型 2との間で一方の補強繊維群 F A上に連 続的に供給されて一方の補強繊維群 F Aに粘着される。そして、一方の補強繊維群 F Aとどもに成形型 2への所定の厚みになるまで連続的に卷き付ける。  Then, the other reinforcing fiber group FC as an axial long fiber reinforcing material drawn out from the reinforcing fiber supply unit 1C and sent by the supply roller 74 is sent out faster than the rotation speed of the molding die 2. As a result, the fibers are continuously supplied between the impregnation tank 61 and the molding die 2 on one reinforcing fiber group FA in an irregular loop or meandering state due to the curl and feed pool. To the reinforcing fiber group FA. Then, it is continuously wound around one of the reinforcing fiber groups F A to the molding die 2 until it reaches a predetermined thickness.
また、成形型 2の上方から成形型 2に卷回された一方の捕強繊維群 F Aおよび他 方の補強繊維群 F Cにノズル 1 0からさらに重合性樹脂組成物 6 Aを噴霧または 滴下し、含浸ロール 1 0 1によって成形型 2の周面に沿うように均レ、パイプ状に 賦形する。その後、光照射装置 3を光重合開始剤が反応を開始する波長の光を成形 型 2の方向に向けて照射し、 光重合反応を開始させる。  Further, the polymerizable resin composition 6A is further sprayed or dropped from the nozzle 10 onto one of the reinforcing fiber groups FA and the other reinforcing fiber group FC wound around the molding die 2 from above the molding die 2, The impregnating roll 101 forms a uniform and pipe shape along the peripheral surface of the mold 2. Thereafter, the light irradiation device 3 is irradiated with light having a wavelength at which the photopolymerization initiator starts a reaction in the direction of the mold 2 to start the photopolymerization reaction.
あるいは、芯型へ卷回時に同時に、後方で光照射装置 3を光重合開始剤が反応を 開始する波長の光を成形型 2の方向に向けて照射し、賦形途中から光重合反応を開 始させる。  Alternatively, simultaneously with the winding around the core mold, the light irradiation device 3 is illuminated in the rear with light having a wavelength at which the photopolymerization initiator starts the reaction in the direction of the molding die 2, and the photopolymerization reaction is started during the shaping. Start.
また、一定の厚みになるまで成形型 2へ卷回し、光照射して硬化させた後、 また 一定の厚みになるまで卷回し、再度光照射させて硬ィ匕させるような多段硬化を行つ てもよい。 In addition, after being wound around the mold 2 until a certain thickness is obtained, and then cured by irradiating light, it is wound again until the thickness becomes a certain thickness, and then subjected to light irradiation again to perform multi-stage curing such as stiffening. You may.
また、成形型 2への卷回と同時に光照射装置 3から光を照射する場合は、卷回中 全時間にわたって、 あるいは、部分的に照射する方法が考えられる。 部分的に照射 する場食は卷回、賦形完了後、やはり光を照射し、光を照射しなかった積層を硬化 させる。  In the case of irradiating the light from the light irradiation device 3 simultaneously with the winding on the molding die 2, a method of irradiating the whole time or partly during the winding can be considered. After the winding and shaping of the partially illuminated table meal, light is again irradiated, and the unirradiated laminate is cured.
また、光照射装置 3からの光の照射は、配合されている光重合開始剤がもっとも 効率良く反応する波長、 及び照射量を選択する。  The light irradiation from the light irradiation device 3 selects a wavelength and an irradiation amount at which the compounded photopolymerization initiator reacts most efficiently.
ま^、高温反応型重合開始剤が配合されている場合には、光重合反応によって発 生する反応熱により高温反応型重合開始剤による重合反応を開始させ、補強繊維な どによって光が照射されにくい肉厚の繊維強ィ匕榭脂パイプ 1 0であっても内部ま で硬化を進めることができる。また、 肉厚が薄い場合も高温反応型重合開始剤を配 合することで硬化のスピードアップを図ることができる。  In the case where a high-temperature reaction type polymerization initiator is blended, the polymerization reaction by the high-temperature reaction type polymerization initiator is started by reaction heat generated by the photopolymerization reaction, and light is irradiated by a reinforcing fiber or the like. The hardening can be advanced to the inside even if the fiber pipe 10 has a small thickness. Even when the thickness is small, the curing speed can be increased by incorporating a high-temperature reaction-type polymerization initiator.
また、可視光を含む波長領域で反応する光重合開始剤が配合されている場合には、 繊維補強材などによつて光が遮断される可能性が高い肉厚の成形体であつても、可 視光により内部まで硬化を進めることができる。また、卷回時に可視光によりゆつ くり硬化が進行するため、 全体の成形速度を上げることができる。  In addition, when a photopolymerization initiator that reacts in the wavelength region including visible light is included, even if the thickness of the molded product is high, the light is likely to be blocked by a fiber reinforcing material or the like. The curing can be advanced to the inside with visible light. In addition, since the film is slowly cured by visible light during winding, the entire molding speed can be increased.
また、肉厚のものを成形する場合には、光の照射が不十分となり硬化不良による クラックが発生する可能性があるため、一定の厚みまで卷き付けた後、光照射を行 つた硬化を行い、その後再度卷き付け、硬ィ匕を行う多段硬化を行うことが有効であ る。 一定の厚みとしては、全体の厚みにもよるが、 2 0 mm以下で、 より好ましく は 8〜 1 5 mmほどで多段硬化を行うこと力 クラックの防止の観点から好ましい。 また、成形速度を上げるためや硬化不良によるクラック防止のため、卷回しなが ら光照射を行ってもよい。その場合には、光の照射量が大きすぎると硬化が早すぎ るため、 層間のクラックが発生しやすい。 .  When molding thick-walled products, light irradiation is insufficient and cracks may occur due to poor curing.Therefore, after winding to a certain thickness, curing by light irradiation is performed. After that, it is effective to carry out multi-stage hardening for re-winding and stiffening. Although it depends on the entire thickness, the constant thickness is preferably not more than 20 mm, more preferably about 8 to 15 mm, from the viewpoint of prevention of force cracks. Light irradiation may be performed while winding to increase the molding speed or prevent cracking due to poor curing. In that case, if the light irradiation amount is too large, the curing is too fast, and cracks between the layers are likely to occur. .
つぎに、所定回数一方の補強繊維群 F Aおよび他方の補強繊維群 F Cを成形型 2 に巻回し終わつたら、成形型 2の回転を停止し、重合性樹脂組成物 6 Aの重合反応 が完了したら、成形型 2から繊維強化樹脂パイプ 1 0を脱型して、繊維強化樹脂パ イブ 1 0が製造される。 Next, when the one reinforcing fiber group FA and the other reinforcing fiber group FC are wound around the molding die 2 a predetermined number of times, the rotation of the molding die 2 is stopped, and the polymerization reaction of the polymerizable resin composition 6A is completed. After the completion of the process, the fiber reinforced resin pipe 10 is removed from the mold 2 to produce the fiber reinforced resin pipe 10.

次に、この実施例 4における構成からなる繊維強化樹脂パイプ 1 0を下記する各 製造条件により製造した。 その結果を以下に説明する。  Next, a fiber reinforced resin pipe 10 having the configuration in Example 4 was manufactured under the following manufacturing conditions. The results will be described below.
まず、第 4— 1製造条件では、成形型 2に捕強繊維 Fを全厚みが 3 0 mmになる まで卷回した。その後、卷回した補強繊維 Fを 1 2 0 wZ c m X 2灯で光照射して 硬化させた。 この光照射による硬化の完了時間は 6 0分であった。 次に、第 4— 2製造条件では、成形型 2に補強繊維 Fを卷回しながら、 8 OwZ cmX 1灯で光照射し、全厚みが 3 Ommになるまで卷回した。 その後、卷回した 補強繊維 Fを 1 20 wZcmX 2灯で光照射して硬化させた。この光照射による硬 化の完了時間は 15分であった。 First, under the 4-1 production conditions, the reinforcing fibers F were wound around the mold 2 until the total thickness became 30 mm. Thereafter, the wound reinforcing fiber F was cured by irradiating it with 120 wZ cm X 2 lamps. The completion time of the curing by the light irradiation was 60 minutes. Next, under the fourth-second production conditions, while the reinforcing fiber F was wound around the molding die 2, light irradiation was performed with one lamp of 8 OwZ cmX, and winding was performed until the total thickness became 3 Omm. After that, the wound reinforcing fiber F was cured by irradiating light with two lights of 120 wZcmX. The completion time of hardening by this light irradiation was 15 minutes.
次に、第 4一 3製造条件では、成形型 2に補強繊維 Fを卷回しながら、 8 Ow/ cmX2灯で光照射し、全厚みが 3 Ommになるまで巻回した。 その後、卷回した 捕強織維 Fを 120w/CmX2灯で光照射して硬化させた。この照射による硬ィ匕 の完了時間は 10分であった。 Next, under the fourth to thirteenth production conditions, the reinforcing fiber F was wound around the mold 2 while irradiating light with an 8 Ow / cmX2 lamp until the entire thickness became 3 Omm. Thereafter, the wound captive fiber F was irradiated with light using a 120 w / C mX2 lamp to be cured. The completion time of the stiffening by this irradiation was 10 minutes.
次に、第 4— 4製造条件では、成形型 2に捕強繊維 Fを巻回しながら、 40 wノ cmX 1灯で光照射し、全厚みが 3 Ommになるまで卷回した。 その後、卷回した 補強繊維 Fを 1 20w/cniX2灯で光照射して硬化させた。この照射による硬化 の完了時間は 60分であった。  Next, under the fourth-fourth production conditions, while the reinforcing fiber F was wound around the molding die 2, light irradiation was performed with a single lamp of 40 wcm x 1 until the total thickness became 3 Omm. Thereafter, the wound reinforcing fiber F was cured by irradiating light with a 120 w / cniX2 lamp. The completion time of curing by this irradiation was 60 minutes.
この実施例 4の各製造条件により製造した繊維強化榭脂パイプ 10の各断面に は、第 4一 1に関する繊維強化樹脂パイプ 10だけに力 ^"かなクラックの発生が見 られたが、 全体的に効率良く繊維強化樹脂パイプ 10の製造を行うことができた。 上記したように、本実施の形態 2にかかる繊維強ィ匕樹脂パイプ 10の製造装置 1、 およびその製造方法は、上記した実施例からもわかるように、以下のような優れた 効果を有している。  In each section of the fiber-reinforced resin pipe 10 manufactured under the respective manufacturing conditions of Example 4, a force crack was generated only in the fiber-reinforced resin pipe 10 relating to the eleventh-first embodiment. As a result, the production apparatus 1 for the fiber-reinforced resin pipe 10 according to the second embodiment and the method for producing the same were as described above. As can be seen from the examples, it has the following excellent effects.
第 1に、光重合開始剤により重合反応を開始させることにより重合反応速度がは やく、生産性が向上する。 また、光重合による反応熱によって高温反応型重合開始 剤による重合反応が開始するため、光が当たらない部分も反応硬化させることがで きる。 し力も、 可視光を含む波長領域で反応する光重合開始剤、連続光照射、 およ び多段光照射の配合により各層とも均等に硬化を促進させることができる。したが つて、 層間のクラック発生を抑制することができる。  First, by initiating a polymerization reaction with a photopolymerization initiator, the polymerization reaction speed is increased and productivity is improved. Further, since the polymerization reaction by the high-temperature reaction-type polymerization initiator is started by the heat of the reaction due to the photopolymerization, it is possible to react and harden the portion not exposed to the light. For each layer, curing can be evenly promoted by blending a photopolymerization initiator that reacts in a wavelength region including visible light, continuous light irradiation, and multi-step light irradiation. Therefore, the occurrence of cracks between layers can be suppressed.
第 2'に、光を当てなければ常温で放置していても反応が急激に開台されないので、 噴霧時にこぼれ落ちた重合性樹脂組成物 6Αをそのまま再利用できる。また、含浸 槽中の重合性樹脂組成物 6 Aの可使時間 （表 1に示すライフ参照) も長く、含浸槽 等の清掃等のメンテナンス作業を軽減でき、 コストダウンを図ることができる。 第 3に、軸方向長繊維強化材はチヨップドストランドでなく連続繊維であるため 、繊維の周囲への飛散がなく、作業環境が良好であるとともに、零れ落ちた重合性 樹脂組成物 6 Aへ混じることもないので、ポンプ 9 3、配管を詰まらせたりするこ となく、榭脂の再利用に好適である。繊維の飛散がないので、 ランプ 3 4表面に補 強繊維 Fが付着して光照射を妨げることもない。 Secondly, the reaction does not open rapidly even if left at room temperature unless exposed to light, so that the polymerizable resin composition 6Α that has fallen off during spraying can be reused as it is. Also impregnated The potable life of the polymerizable resin composition 6A in the tank (see the life shown in Table 1) is long, and maintenance work such as cleaning of the impregnation tank and the like can be reduced, and costs can be reduced. Third, since the axially long fiber reinforcing material is not a chopped strand but a continuous fiber, there is no scattering around the fiber, the working environment is good, and the polymerizable resin composition 6A that has spilled out. It is suitable for reuse of resin without clogging the pump 93 and piping because it does not mix. Since there is no scattering of fibers, the reinforcing fibers F do not adhere to the surface of the lamp 34 and do not hinder light irradiation.
なお、本実施の形態 2では、一方の補強繊維群 F Aに重合性樹脂組成物 6 Aを含 浸したのち、他方の補強繊維群 F Cを一方の補強繊維群 F Aの上に供給するように しているが、 これに限定されない。例えば、一方の補強繊維群 F Aと一方の補強繊 維群 F Aとの間に他方の捕強繊維群 F Cをはさみ込んだ状態で一方の補強繊維群 F Aとともに他方の捕強繊維群 F Cを含浸槽に通し、含浸槽 6 1で一方の捕強繊維 群 F Aに重合性樹脂組成物 6 Aを含浸すると同時に、他方の補強繊維群 F Cにも重 合性樹脂組成物 6 Aを含浸するようにしても構わない。  In Embodiment 2, one of the reinforcing fiber groups FA is impregnated with the polymerizable resin composition 6A, and then the other reinforcing fiber group FC is supplied onto the one reinforcing fiber group FA.

Instead, for example, the trapezoidal mechanism may be used to meander irregularly. In this case, since the shape becomes a meandering shape or a loop shape at random, even if the direction overlaps with one of the reinforcing fiber groups FA, no crack is generated.
また、本実施の形態 2では、製造する繊維強化樹脂パイプ 1 0の強度を捕うため • にガラス繊維ロービングからなる補強繊維 Fのみが用いられているが、これに限定 されるものではなく、補強繊維 Fに加え必要に応じて、製造する繊維強化樹脂パイ プ 1 0の内面側おょぴ外面側に不織布等を積層してもよく、また、厚み方向の中央 部 （積層途中） にネット状、 クロス状、 マット状の補強材を積層してもよレ、。 また、 本実施の形態 2において製造された繊維補強榭脂パイプ 1 0の筒状体に、 同軸上にゴム製からなる筒状体が備えられてもよく、繊維補強樹脂パイプ 1 0の強 度向上に好ましい。 産業上の利用可能性 Further, in the second embodiment, only the reinforcing fiber F made of glass fiber roving is used to capture the strength of the fiber reinforced resin pipe 10 to be manufactured, but the present invention is not limited to this.
