Description

本発明は、プリプレグ部材の製造方法に係り、例えば、高圧の水素を貯蔵する高圧ガスタンク等のプリプレグ部材の製造方法に関するものである。   The present invention relates to a method for manufacturing a prepreg member, for example, a method for manufacturing a prepreg member such as a high-pressure gas tank that stores high-pressure hydrogen.

従来から、例えば高圧の水素を貯蔵する高圧ガスタンク等のプリプレグ部材を製造する方法として、熱硬化性樹脂（例えば、エポキシ樹脂）を繊維（例えば、炭素繊維）に含浸させたプリプレグを、フィラメントワインディング法（ＦＷ法）を利用して中空のライナの外側に巻付けた後に、加熱して熱硬化性樹脂を硬化させる方法がある（例えば、下記特許文献１参照）。   Conventionally, as a method for producing a prepreg member such as a high-pressure gas tank for storing high-pressure hydrogen, for example, a filament winding method is employed in which a prepreg obtained by impregnating a fiber (for example, carbon fiber) with a thermosetting resin (for example, an epoxy resin) is used. There is a method in which the thermosetting resin is cured by heating after being wound around the outside of the hollow liner using the (FW method) (for example, see Patent Document 1 below).

また、特許文献２には、上記のような高圧ガスタンクの製造において、当該高圧ガスタンクの性能向上やプリプレグの硬化時間の短縮等のために、紫外線硬化性樹脂が含浸された繊維に紫外線を照射しつつ、前記繊維をライナの外周に巻回して繊維強化樹脂層を形成し、それにより得られたタンク中間品を加熱して、前記巻回された繊維を硬化させる方法が提案されている。   Further, in Patent Document 2, in the production of a high-pressure gas tank as described above, a fiber impregnated with an ultraviolet-curable resin is irradiated with ultraviolet rays in order to improve the performance of the high-pressure gas tank or shorten the curing time of the prepreg. On the other hand, a method has been proposed in which the fiber is wound around the outer periphery of the liner to form a fiber reinforced resin layer, and a tank intermediate product obtained thereby is heated to cure the wound fiber.

ところで、前記高圧ガスタンクの強度を確保するためには、熱硬化性樹脂を含浸させた繊維（プリプレグ）をライナに対して正しい位置、角度で巻付ける必要がある。しかし、前記繊維は、一般に複数層に亘ってライナに巻付けられるので、視認性が悪く、前記繊維の巻付け状態を確認するためには、巻付け工程を一旦中断し、作業者が経験等に基づいて前記繊維を目視にて識別して前記巻付け状態を確認する必要があった。そのため、確認作業に多くの時間がかかって生産性が低下するという問題や、巻付け工程を途中で中断することで巻付け状態が不連続となり、当該高圧ガスタンクの強度が低下してしまう可能性があった。   By the way, in order to ensure the strength of the high-pressure gas tank, it is necessary to wind a fiber (prepreg) impregnated with a thermosetting resin at a correct position and angle with respect to the liner. However, since the fiber is generally wound around the liner over a plurality of layers, the visibility is poor, and in order to confirm the winding state of the fiber, the winding process is temporarily interrupted, and the operator experiences it, etc. It is necessary to visually identify the fiber based on the above and confirm the winding state. Therefore, there is a possibility that the productivity will be reduced due to a long time for the confirmation work, and that the winding state becomes discontinuous by interrupting the winding process in the middle and the strength of the high-pressure gas tank may be reduced. was there.

本発明は上記する問題に鑑みてなされたものであり、熱硬化性樹脂を繊維に含浸させたプリプレグから作製されるプリプレグ部材を製造するに当たり、生産性を低下させることなく、当該プリプレグ部材の強度を確実に確保することのできるプリプレグ部材の製造方法を提供することを目的とする。   The present invention has been made in view of the above-described problems, and in producing a prepreg member produced from a prepreg in which a fiber is impregnated with a thermosetting resin, the strength of the prepreg member is reduced without reducing productivity. It aims at providing the manufacturing method of the prepreg member which can ensure reliably.

前記目的を達成すべく、本発明によるプリプレグ部材の製造方法は、繊維に熱硬化性樹脂を含浸させる含浸工程と、前記熱硬化性樹脂を含浸した前記繊維をライナに巻付ける巻付け工程と、前記熱硬化性樹脂を硬化させる硬化工程と、を含むプリプレグ部材の製造方法であって、前記含浸工程において、一部の繊維に含浸させる熱硬化性樹脂に蛍光剤を添加し、前記巻付け工程において、前記ライナに紫外光を照射しながら前記繊維の巻付けを行う方法である。   In order to achieve the above object, a method of manufacturing a prepreg member according to the present invention includes an impregnation step of impregnating a fiber with a thermosetting resin, and a winding step of winding the fiber impregnated with the thermosetting resin around a liner, A curing step of curing the thermosetting resin, wherein in the impregnation step, a fluorescent agent is added to the thermosetting resin impregnated into some fibers, and the winding step In the method, the fiber is wound while irradiating the liner with ultraviolet light.

本発明によれば、蛍光剤が添加された繊維（プリプレグ）が巻付け工程にて紫外光によって発光するので、ライナに対して繊維の巻付けを行いながら当該ライナに対する繊維の位置、角度を確認できるため、プリプレグ部材の製造に当たり、生産性を低下させることなく、当該プリプレグ部材の強度を確実に確保することが可能となる。   According to the present invention, since the fiber (prepreg) to which the fluorescent agent is added emits light by ultraviolet light in the winding process, the position and angle of the fiber relative to the liner are confirmed while the fiber is wound around the liner. Therefore, when manufacturing the prepreg member, the strength of the prepreg member can be reliably ensured without reducing the productivity.

以下、図面を参照して本発明によるプリプレグ部材の製造方法の実施形態を説明する。   Hereinafter, an embodiment of a method for producing a prepreg member according to the present invention will be described with reference to the drawings.

なお、以下では、主に、例えば燃料電池自動車の水素を貯蔵するための、炭素繊維からなる繊維束であるトウにエポキシ樹脂からなる熱硬化性樹脂を含浸させたトウプリプレグ（ＴＰＰ：Tow-Prepreg）が外殻部分等に使用される高圧ガスタンクを製造するための製造方法について説明するが、本発明は、シャフト、外板等のプリプレグ部材、また、トウプリプレグ以外の形態のプリプレグから作製されるプリプレグ部材を製造するための製造方法にも適用できることは勿論である。   In the following, a tow prepreg (TPP: Tow-Prepreg) in which a thermosetting resin made of an epoxy resin is impregnated mainly with a tow which is a fiber bundle made of carbon fiber for storing hydrogen of a fuel cell vehicle, for example. ) Is a manufacturing method for manufacturing a high-pressure gas tank used for an outer shell portion or the like, but the present invention is made from a prepreg member such as a shaft and an outer plate, and a prepreg of a form other than a toe prepreg. Of course, the present invention can also be applied to a manufacturing method for manufacturing a prepreg member.

図１は、本発明によるプリプレグ部材としての高圧ガスタンクの製造方法を説明するフロー図である。また、図２は、プリプレグの製造装置の一例の全体構成を示す概略図、図３は、図２に示すプリプレグの製造装置で製造されたプリプレグを使用した、高圧ガスタンクの製造装置の一例の全体構成を示す概略図である。   FIG. 1 is a flowchart for explaining a method for producing a high-pressure gas tank as a prepreg member according to the present invention. FIG. 2 is a schematic diagram showing an overall configuration of an example of a prepreg manufacturing apparatus. FIG. 3 is an overall example of an apparatus for manufacturing a high-pressure gas tank using the prepreg manufactured by the prepreg manufacturing apparatus shown in FIG. It is the schematic which shows a structure.

図１に示すように、本実施形態による高圧ガスタンクの製造方法は、基本的に、繊維束（糸状の繊維（フィラメント）を数千〜数万本程度束ねたもの）にマトリックス樹脂である熱硬化性樹脂を含浸してなるプリプレグ（トウプリプレグ）を製造するプリプレグ製造工程（Ｓ１）と、プリプレグ製造工程（Ｓ１）にて製造されたプリプレグを複数（束）使用して、ＦＷ法により高圧ガスタンクを製造する高圧ガスタンク製造工程（Ｓ２）とで構成されている。   As shown in FIG. 1, the manufacturing method of the high-pressure gas tank according to the present embodiment is basically a thermosetting that is a matrix resin in a bundle of fibers (thousands to tens of thousands of filaments (filaments)). A prepreg manufacturing process (S1) for manufacturing a prepreg (toe prepreg) impregnated with a conductive resin, and a plurality of (bundles) of prepregs manufactured in the prepreg manufacturing process (S1) And a high-pressure gas tank manufacturing process (S2) to be manufactured.

前記プリプレグ製造工程（Ｓ１）は、主に、繊維束を形成する繊維基材を巻出し用ボビンから巻出す繊維基材巻出し工程（Ｓ１１）、繊維束に未硬化の熱硬化性樹脂を含浸させる含浸工程（Ｓ１２）、熱硬化性樹脂が含浸された繊維束であるプリプレグを巻取り用ボビンに巻取るプリプレグ巻取り工程（Ｓ１３）を含んでいる。   The prepreg manufacturing step (S1) mainly includes a fiber base material unwinding step (S11) in which a fiber base material forming a fiber bundle is unwound from an unwinding bobbin, and the fiber bundle is impregnated with an uncured thermosetting resin. An impregnation step (S12), and a prepreg winding step (S13) of winding a prepreg which is a fiber bundle impregnated with a thermosetting resin onto a winding bobbin.

そして、本実施形態では、前記含浸工程（Ｓ１２）において、後段の高圧ガスタンク製造工程（Ｓ２）でライナに巻付けられる一部の繊維束に含浸させる熱硬化性樹脂に蛍光剤を添加する。   In this embodiment, in the impregnation step (S12), a fluorescent agent is added to the thermosetting resin impregnated in a part of the fiber bundle wound around the liner in the subsequent high-pressure gas tank manufacturing step (S2).

より詳しくは、例えば、図２に示されるように、前記プリプレグ製造工程（Ｓ１）を実施するプリプレグの製造装置１０では、繊維束５を形成する繊維基材３を巻出し用ボビン１１に巻かれた状態から巻出し（繊維基材巻出し工程（Ｓ１１））、開繊、加熱等の前処理を施して繊維束５を作製した後、所定温度に加熱された複数（図示例では、２個）の含浸ローラ１２ａ、１２ｂに沿って繊維束５を送ることにより、当該繊維束５に熱硬化性樹脂６を含浸させる（含浸工程（Ｓ１２））。なお、ここでは、樹脂が塗工された含浸ローラ１２ａ、１２ｂに繊維束５を接触させる方法によって、繊維束５にマトリックス樹脂である熱硬化性樹脂６を含浸しているが、樹脂溶液を貯留した浸漬槽に繊維束を浸漬して含浸させる方法、繊維束の上から樹脂を塗布した後に加圧ローラ等により加圧する方法等の他の工程によって、前記繊維束５に熱硬化性樹脂６を含浸させても良い。   More specifically, for example, as shown in FIG. 2, in the prepreg manufacturing apparatus 10 that performs the prepreg manufacturing step (S 1), the fiber base material 3 that forms the fiber bundle 5 is wound around an unwinding bobbin 11. The fiber bundle 5 is prepared by performing pretreatment such as unwinding (fiber substrate unwinding step (S11)), fiber opening, heating, and the like, and then a plurality of (two in the illustrated example) heated to a predetermined temperature. ) Is impregnated with the thermosetting resin 6 by impregnating the fiber bundle 5 along the impregnation rollers 12a and 12b (impregnation step (S12)). Here, the fiber bundle 5 is impregnated with the thermosetting resin 6 which is a matrix resin by the method in which the fiber bundle 5 is brought into contact with the impregnating rollers 12a and 12b coated with resin, but the resin solution is stored. The thermosetting resin 6 is applied to the fiber bundle 5 by other processes such as a method of immersing and impregnating the fiber bundle in the dipping bath, a method of applying a resin from above the fiber bundle and pressurizing with a pressure roller or the like. It may be impregnated.

含浸ローラ１２ａ、１２ｂを通過して熱硬化性樹脂６が含浸された繊維束からなるプリプレグ７は、回転軸（不図示）周りに回転自在に配置された複数（図示例では、５個）の搬送ローラ１３ａ〜１３ｅの表面（外周面）に順次に沿うようにして搬送され、加熱等の後処理が施された後に、所定の回転速度で回転する巻取り用ボビン１５に巻取られる（プリプレグ巻取り工程（Ｓ１３））。   A plurality of (five in the illustrated example) prepregs 7 each including a fiber bundle that has been impregnated with the thermosetting resin 6 through the impregnating rollers 12a and 12b are rotatably arranged around a rotating shaft (not shown). After being sequentially conveyed along the surface (outer peripheral surface) of the conveying rollers 13a to 13e, and after being subjected to post-processing such as heating, it is wound on a winding bobbin 15 that rotates at a predetermined rotational speed (prepreg Winding step (S13)).

ここで、前記プリプレグ製造工程（Ｓ１）では、後段の高圧ガスタンク製造工程（Ｓ２）で使用される複数本（束）のプリプレグが製造されることになるが、そのうちの一部（本例では、高圧ガスタンク製造工程（Ｓ２）で使用される５本のプリプレグのうちの１本）の製造工程において、前記含浸工程（Ｓ１２）にて、繊維束５に含浸される熱硬化性樹脂６に蛍光剤が添加されており、蛍光剤が添加された熱硬化性樹脂６が繊維束５に含浸され、製造後のプリプレグ７（に含浸される熱硬化性樹脂６）が紫外光によって発光するようになっている。なお、蛍光剤の添加量は、熱硬化性樹脂６の特性に影響しない量（例えば、1%以下）とする。   Here, in the prepreg manufacturing step (S1), a plurality of (bundles) of prepregs used in the subsequent high-pressure gas tank manufacturing step (S2) are manufactured, but some of them (in this example, In the manufacturing process of one of the five prepregs used in the high-pressure gas tank manufacturing process (S2), a fluorescent agent is added to the thermosetting resin 6 impregnated in the fiber bundle 5 in the impregnation process (S12). Is added, the fiber bundle 5 is impregnated with the thermosetting resin 6 to which the fluorescent agent is added, and the prepreg 7 (the thermosetting resin 6 impregnated therein) after production emits light by ultraviolet light. ing. The addition amount of the fluorescent agent is set to an amount that does not affect the characteristics of the thermosetting resin 6 (for example, 1% or less).

前記プリプレグ製造工程（Ｓ１）に続いて前記高圧ガスタンク製造工程（Ｓ２）は、図１に示すように、基本的に、前記プリプレグ製造工程（Ｓ１）で製造された複数本のプリプレグをボビン（巻取り用ボビン）から巻出すプリプレグ巻出し工程（Ｓ２１）、複数本のプリプレグを集束してライナに巻付ける巻付け工程（Ｓ２２）、プリプレグに含まれる熱硬化性樹脂を硬化させる硬化工程（Ｓ２３）を含んでいる。   Following the prepreg manufacturing step (S1), the high-pressure gas tank manufacturing step (S2) basically includes a plurality of prepregs manufactured in the prepreg manufacturing step (S1), as shown in FIG. Prepreg unwinding step (S21) unwinding from the take-up bobbin), a winding step (S22) for converging a plurality of prepregs and winding them around the liner, and a curing step for curing the thermosetting resin contained in the prepreg (S23) Is included.

そして、本実施形態では、前記巻付け工程（Ｓ２２）において、前記ライナに紫外光を照射しながら前記プリプレグの巻付けを行うとともに、前記ライナに巻付けられるプリプレグを撮影した画像からライナに対するプリプレグの巻付け状態を確認する。   In the present embodiment, in the winding step (S22), the prepreg is wound while irradiating the liner with ultraviolet light, and an image of the prepreg wound on the liner is taken from the image of the prepreg on the liner. Check the winding state.

より詳しくは、例えば、図３に示されるように、前記高圧ガスタンク製造工程（Ｓ２）を実施する高圧ガスタンクの製造装置１では、前記プリプレグの製造装置１０で作製された複数本のプリプレグ７ａ〜７ｅ（図示例では、５本であって、そのうちの１本のプリプレグ７ａに含浸される熱硬化性樹脂には蛍光剤が添加されている）がそれぞれボビン１５ａ〜１５ｅに巻付けられており、前記複数本のプリプレグ７ａ〜７ｅを、各ボビン１５ａ〜１５ｅに巻付けられた状態から、各ボビン１５ａ〜１５ｅに対応して配置された供給ローラ１６ａ〜１６ｅ、入口ローラ１７、複数（図示例では、２個）のダンサーローラ１８ａ、１８ｂ、複数（図示例では、３個）の給糸ローラ１９ａ〜１９ｃを介して繰出し装置（例えば、アイトラバース装置）２０まで搬送する（プリプレグ巻出し工程（Ｓ２１））。入口ローラ１７では、各供給ローラ１６ａ〜１６ｅから送り出された各プリプレグ７ａ〜７ｅを受け入れるとともに、各プリプレグ７ａ〜７ｅを例えば並列に整列させて送り出す。ダンサーローラ１８ａ、１８ｂでは、例えば各ダンサーローラ１８ａ、１８ｂが所定の軸を回転中心として揺動したり上下動したりすることで、搬送中の各プリプレグ７ａ〜７ｅに生じる張力を調整する。   More specifically, for example, as shown in FIG. 3, in the high-pressure gas tank manufacturing apparatus 1 that performs the high-pressure gas tank manufacturing step (S 2), a plurality of prepregs 7 a to 7 e manufactured by the prepreg manufacturing apparatus 10 are used. (In the illustrated example, there are five, and a fluorescent agent is added to the thermosetting resin impregnated in one of the prepregs 7a) and wound around the bobbins 15a to 15e, respectively, From a state where a plurality of prepregs 7a to 7e are wound around the bobbins 15a to 15e, supply rollers 16a to 16e, inlet rollers 17, and a plurality (in the illustrated example, A two-way dancer rollers 18a and 18b, and a plurality of (three in the illustrated example) yarn supply rollers 19a to 19c are used to feed out (for example, an eye traverse device). Carrying up to 20 (prepreg unwinding step (S21)). The entrance roller 17 receives the prepregs 7a to 7e sent out from the supply rollers 16a to 16e, and sends out the prepregs 7a to 7e arranged in parallel, for example. In the dancer rollers 18a and 18b, for example, the dancer rollers 18a and 18b swing or move up and down around a predetermined axis to adjust the tension generated in the prepregs 7a to 7e being conveyed.

次いで、前記複数の給糸ローラ１９ａ〜１９ｃに順次に沿うようにして繰出し装置２０まで搬送された各プリプレグ７ａ〜７ｅを、緊密に纏めて当該繰出し部２０から繰出し、所定の回転速度で回転するライナ２１の外周部分に繰り返し（つまり、連続的に且つ複数層に亘って）巻付ける（巻付け工程（Ｓ２２））。このとき、前記ライナ２１の周りの所定箇所に発光装置２２と撮影装置（例えば、カメラ）２３をそれぞれ配置しておき、前記発光装置２２からライナ２１（の表面）に紫外光を照射するとともに、前記撮影装置２３によって前記ライナ２１及びライナ２１に巻付けられるプリプレグ７ａ〜７ｅ（そのうちの紫外光が照射される部分）を撮影する。   Next, the prepregs 7a to 7e conveyed to the feeding device 20 along the plurality of yarn feeding rollers 19a to 19c in sequence are tightly gathered from the feeding unit 20 and rotated at a predetermined rotation speed. It winds around the outer periphery of the liner 21 repeatedly (that is, continuously and over a plurality of layers) (winding step (S22)). At this time, a light emitting device 22 and a photographing device (for example, a camera) 23 are respectively arranged at predetermined locations around the liner 21, and the light emitting device 22 irradiates the liner 21 (the surface thereof) with ultraviolet light, The photographing device 23 photographs the liner 21 and the prepregs 7a to 7e wound around the liner 21 (parts irradiated with ultraviolet light).

この巻付け時において、前記ライナ２１に対する各プリプレグ７ａ〜７ｅの位置や角度は、繰出し装置２０やライナ２１（の回転速度）等を制御することによって変更されるが、本実施形態では、前記ライナ２１に同時に巻付けられるプリプレグ７ａ〜７ｅの一部（図示例では、５本のプリプレグ７ａ〜７ｅのうちの蛍光剤が添加されている１本のプリプレグ７ａ）が、発光装置２２から照射される紫外光によって発光する（図４参照）。そのため、前記撮影装置２３によって撮影される画像を不図示の画像処理装置等によって逐次解析することにより、前記ライナ２１にプリプレグ７ａ〜７ｅを巻付けながら（すなわち、巻付け工程を停止することなく）、前記ライナ２１に対する各プリプレグ７ａ〜７ｅの位置、角度（特に、蛍光剤が添加されたプリプレグ７ａの位置、角度）といった品質保証に必要な巻付け状態を確認できる。   At the time of winding, the positions and angles of the prepregs 7a to 7e with respect to the liner 21 are changed by controlling the feeding device 20, the liner 21 (rotational speed thereof), and the like in the present embodiment. A part of the prepregs 7 a to 7 e wound simultaneously around the light 21 (in the illustrated example, one prepreg 7 a to which a fluorescent agent among the five prepregs 7 a to 7 e is added) is irradiated from the light emitting device 22. Light is emitted by ultraviolet light (see FIG. 4). Therefore, by sequentially analyzing an image photographed by the photographing device 23 with an image processing device or the like (not shown), the prepregs 7a to 7e are wound around the liner 21 (that is, without stopping the winding step). The winding state necessary for quality assurance such as the position and angle of each prepreg 7a to 7e with respect to the liner 21 (particularly, the position and angle of the prepreg 7a to which the fluorescent agent is added) can be confirmed.

そして、プリプレグ７ａ〜７ｅが巻付けられたライナ２１を加熱炉内に収容して前記プリプレグ７ａ〜７ｅに含まれる熱硬化性樹脂６を硬化させた後（硬化工程（Ｓ２３））、樹脂硬化後のライナ２１を加熱炉内から取り出し、冷却及びバリ等の除去を行う。これにより、中空のライナ２１の外周を覆うようにプリプレグ７ａ〜７ｅからなる繊維強化樹脂層が形成された高圧ガスタンクが製造される。   Then, after the liner 21 around which the prepregs 7a to 7e are wound is accommodated in a heating furnace and the thermosetting resin 6 contained in the prepregs 7a to 7e is cured (curing step (S23)), after the resin is cured. The liner 21 is taken out of the heating furnace, and cooling and removal of burrs are performed. Thereby, the high pressure gas tank in which the fiber reinforced resin layer made of the prepregs 7a to 7e is formed so as to cover the outer periphery of the hollow liner 21 is manufactured.

このように、本実施形態によれば、蛍光剤が添加された繊維束からなるプリプレグが巻付け工程（Ｓ２２）にて紫外光によって発光するので、ライナ２１に対してプリプレグの巻付けを行いながら（すなわち、巻付け工程を停止することなく）当該ライナ２１に対するプリプレグの位置、角度を確認できるため、高圧ガスタンク等のプリプレグ部材の製造に当たり、生産性を低下させることなく、当該プリプレグ部材の強度を確実に確保することが可能となる。   Thus, according to the present embodiment, the prepreg composed of the fiber bundle to which the fluorescent agent is added emits light by the ultraviolet light in the winding step (S22), so that the prepreg is wound around the liner 21. Since the position and angle of the prepreg with respect to the liner 21 can be confirmed (ie, without stopping the winding process), the strength of the prepreg member can be reduced without reducing productivity in the manufacture of a prepreg member such as a high-pressure gas tank. It is possible to ensure with certainty.

また、抜き取り検査等ではなく、製造対象となるプリプレグ部材の全数に対して前記プリプレグの巻付け状態を検査できるため、これによっても、品質保証レベルを向上させることが可能となる。   Moreover, since the winding state of the prepreg can be inspected with respect to the total number of prepreg members to be manufactured instead of sampling inspection or the like, it is possible to improve the quality assurance level.

なお、上記実施形態では、炭素繊維からなる繊維束であるトウにエポキシ樹脂からなる熱硬化性樹脂を含浸させたトウプリプレグを用いて、プリプレグ部材である高圧ガスタンクを製造する製造方法について説明したが、プリプレグ部材を形成する繊維（束）や熱硬化性樹脂は、適宜のものを選択し得る。例えば、繊維としては、前述した炭素繊維の他、例えば、ボロンやアルミナ、炭化ケイ素、窒化ケイ素、ジルコニアなどのセラミック繊維、ガラス繊維などの無機繊維、銅や鋼、アルミニウム、ステンレスなどの金属繊維、ポリアミドやポリエステル、セルロース、ポリプロピレン、ポリエチレンなどの有機繊維のいずれか一種もしくは二種以上の混合物を採用し得る。また、熱硬化性樹脂としては、前述したエポキシ樹脂の他、例えば、フェノール樹脂、メラミン樹脂、不飽和ポリエステル樹脂、ポリウレタンなどを採用し得る。   In the above embodiment, the production method for producing a high-pressure gas tank that is a prepreg member using a tow prepreg obtained by impregnating a thermosetting resin made of an epoxy resin into a tow that is a fiber bundle made of carbon fibers has been described. As the fibers (bundles) and the thermosetting resin forming the prepreg member, appropriate ones can be selected. For example, as the fiber, in addition to the carbon fiber described above, for example, ceramic fiber such as boron, alumina, silicon carbide, silicon nitride, zirconia, inorganic fiber such as glass fiber, metal fiber such as copper, steel, aluminum, stainless steel, Any one or a mixture of two or more organic fibers such as polyamide, polyester, cellulose, polypropylene, and polyethylene may be employed. Moreover, as a thermosetting resin, a phenol resin, a melamine resin, an unsaturated polyester resin, a polyurethane etc. other than the epoxy resin mentioned above can be employ | adopted, for example.

また、上記実施形態では、ライナに同時に巻付けられる複数本（５本）のプリプレグのうちの１本に含浸させる熱硬化性樹脂に蛍光剤を添加しているが、例えば、ライナに同時に巻付けられる複数本のプリプレグのうちの複数本（例えば、５本のプリプレグのうちの４本等）に蛍光剤を添加しても良い。この場合、前記撮影装置で撮影された画像から、蛍光剤が添加されていないプリプレグのライナに対する位置や角度を検出して、前記ライナに対する各プリプレグの位置、角度を確認することもできる。また、例えば、ライナに同時に巻付けられるプリプレグを偶数本用意し、奇数側を蛍光剤有りとし、偶数側を蛍光剤無しとすることで、ライナに同時に巻付けられる全てのプリプレグの位置や角度を精緻に検出することも可能となる。   Moreover, in the said embodiment, although the fluorescent agent is added to the thermosetting resin impregnated to one of the multiple (5) prepregs wound simultaneously around a liner, for example, it winds around a liner simultaneously A fluorescent agent may be added to a plurality of the plurality of prepregs (for example, four of the five prepregs). In this case, the position and angle of each prepreg with respect to the liner can be confirmed by detecting the position and angle of the prepreg to which the fluorescent agent is not added from the image photographed by the photographing apparatus. Also, for example, by preparing an even number of prepregs that are wound simultaneously on the liner, with the odd number side having a fluorescent agent and the even side having no fluorescent agent, the positions and angles of all the prepregs that are simultaneously wound on the liner can be set. It becomes possible to detect precisely.

また、上記実施形態では、プリプレグ製造工程（Ｓ１）と高圧ガスタンク製造工程（Ｓ２）とを分離し、予め繊維（束）に熱硬化性樹脂が含浸されたプリプレグを用いてフィラメントワインディングを行う、いわゆる、ドライ法のＦＷ法を利用しているが、例えば、フィラメントワインディングの途中に、繊維（束）に熱硬化性樹脂を含浸する工程を含む、いわゆる、ウェット法のＦＷ法を利用しても良い。この場合、製品形状を形作るライナに巻回される直前にプリプレグが作製される。   In the above embodiment, the prepreg manufacturing step (S1) and the high-pressure gas tank manufacturing step (S2) are separated, and filament winding is performed using a prepreg in which a fiber (bundle) is impregnated with a thermosetting resin in advance. The dry FW method is used. For example, a so-called wet FW method including a step of impregnating a fiber (bundle) with a thermosetting resin in the middle of filament winding may be used. . In this case, the prepreg is produced immediately before being wound around the liner that forms the product shape.

以上、本発明の実施の形態を図面を用いて詳述してきたが、具体的な構成はこの実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲における設計変更等があっても、それらは本発明に含まれるものである。   The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. They are also included in the present invention.
