Description

　この発明は、軽量・強靭であってリサイクル性を備えることを目的とした複合強化原糸を用いた編成物に関する。 {Circle over (1)} The present invention relates to a knitted fabric using a composite reinforced yarn intended to be lightweight, tough, and recyclable.

　従来複合材料としては、熱硬化性複合材料が主流とされているが、熱硬化性複合材料は、その成形性の簡易さ、力学的特性の優れた点において注目されている反面、近年の環境への配慮、リサイクル性から熱可塑性複合材料への関心が高まっている。 Conventionally, thermosetting composite materials have been predominantly used as composite materials. Thermosetting composite materials have attracted attention due to their simplicity in forming properties and excellent mechanical properties, but in recent years environmental Due to concerns about recycling and recyclability, interest in thermoplastic composite materials is increasing.

　現在製品化されている熱可塑性マトリックス成形材料としては炭素繊維とＰＥＥＫを組み合わせた一方向プリプレグ材があり、航空機材料などの大型成形に応用が進められているが、前記プリプレグ材は板状で固く、粘着性がないため積層しにくいなどの問題点がある。従って製造が難しいことにより、成形コストが高くつき、複雑形状形成品への応用が困難とされている。そこでドレープ性を改善するための開発研究が行われ、一方のプリプレグ材を短冊状にした含浸プリプレグテープや、未含浸の強化材とフィルム状の高分子シートを積層し、プレスする成形方法、フィルムスタッキング法が開発された。例えば積層材とした含浸プリプレグテープは、熱可塑性樹脂が含浸してあるため、成形品作成時に強化繊維への含浸が不必要であり、成形サイクルの短縮において有利ではあるものの、二次加工性に乏しくプリフォーミング時に問題となり、一方向プリプレグ材のように板状でないにしても、ドレープ性に関しては低いものとなっている。 As a thermoplastic matrix molding material that is currently being commercialized, there is a unidirectional prepreg material combining carbon fiber and PEEK, which is being applied to large-scale molding of aircraft materials, etc., but the prepreg material is plate-like and hard. There is a problem that it is difficult to laminate because of lack of adhesiveness. Therefore, it is said that the production is difficult, the molding cost is high, and application to a product having a complicated shape is difficult. Therefore, development research was carried out to improve drapability, and impregnated prepreg tape in which one of the prepreg materials was made into a strip shape, or a non-impregnated reinforcing material and a film-like polymer sheet were laminated and pressed. Stacking methods have been developed. For example, the impregnated prepreg tape used as a laminated material is impregnated with a thermoplastic resin, so that it is not necessary to impregnate the reinforcing fibers at the time of forming a molded product, which is advantageous in shortening the molding cycle. It is poor and causes a problem at the time of preforming, and the drapability is low even if it is not plate-shaped like a unidirectional prepreg material.

　前記のように、ドレープ性に優れた繊維状の高含浸材料の開発が行われた。繊維状の含浸材料を用いることにより、テキスタイル成形品を作製し、それをプリフォームとすることで、ドレープ性の改善が行われた。繊維状含浸材料の問題点は、フィルムスタッキング法の際にも問題点に上ったように、マトリックス樹脂の強化繊維への含浸である。熱可塑性樹脂の溶融粘度は、硬化前の熱硬化性樹脂と比較して、極めて高いことが知られている。熱硬化性樹脂としては、エポキシ樹脂、熱可塑性樹脂としては、ＰＡ６樹脂を例にとると、前者は数十ポイス(Poise)なのに対し、後者は数百〜数千ポイスである。前記のように高い溶融粘度が熱可塑性複合材料における低い含浸性のもととなっている。 繊 維 As described above, a fibrous highly impregnated material having excellent drapability has been developed. By using a fibrous impregnating material, a textile molded product was produced and used as a preform, thereby improving the drapability. The problem with the fibrous impregnating material is the impregnation of the matrix resin into the reinforcing fibers, as was the case with the film stacking method. It is known that the melt viscosity of a thermoplastic resin is extremely higher than that of a thermosetting resin before curing. Taking the epoxy resin as the thermosetting resin and the PA6 resin as the thermoplastic resin, the former has several tens of poise, while the latter has several hundred to several thousand poise. As mentioned above, the high melt viscosity is responsible for the low impregnation of the thermoplastic composite.

　熱可塑性複合材料の含浸性の改善のためには、マトリックス樹脂と強化繊維が近くに存在することが望まれる。前記により、マトリックスを繊維状にし、強化繊維と混合したカミングレッドヤーン(Commingled yarn)やマトリックス樹脂を粉末状にし、強化繊維に均一にまぶしたパウダーイムプレグネーテッドヤーン(Powder Impregnated yarn)の開発が行われた。
特開平１１−２９３５３５ 特開平５−１０６１１６ In order to improve the impregnating property of the thermoplastic composite material, it is desirable that the matrix resin and the reinforcing fiber are present in the vicinity. With the above, the development of powder impregnated yarn (Powder Impregnated yarn) in which the matrix is made into a fibrous form, the cumming red yarn (Commingled yarn) mixed with the reinforcing fiber or the matrix resin is made into a powder form, and the reinforcing fiber is evenly spread on the reinforcing fiber. It was conducted.
JP-A-11-293535 JP-A-5-106116

　前記熱可塑性複合材料は、樹脂の溶融粘度が高い為に繊維束への含浸が困難なこと、及び成形温度が高いなどの問題点があった。 The thermoplastic composite material has problems such as difficulty in impregnating the fiber bundle due to high melt viscosity of the resin and high molding temperature.

　前記フィルムスタッキング法は、未含浸のプリフォームを積層しているため複雑形状への適用は困難なもの、曲面の追従性はこれまでのプリプレグ材と比較すると向上している。しかし未含浸のプリフォームを使用しているため含浸性に乏しく、含浸には高温、高圧のもと形成に長時間を要する問題点がある。 フ ィ ル ム The film stacking method is difficult to apply to a complicated shape because an unimpregnated preform is laminated, but the followability of a curved surface is improved as compared with conventional prepreg materials. However, since an unimpregnated preform is used, the impregnating property is poor, and there is a problem that impregnation requires a long time to form under high temperature and high pressure.

　またパウダーインプレグネーテッドヤーンは、熱可塑性樹脂を粉末化し、強化繊維にまぶすことにより含浸性の向上をねらったものであるが、樹脂パウダーの付着が不均一となり、それをコントロールするのが困難であるという問題点を有する。また樹脂パウダーがこぼれ落ちるため作業性が悪いが、これを防止する為に、前記樹脂パウダーと同じ樹脂からなる外殻で覆うことによって作業性を向上させた材料も開発されている。 Powder impregnated yarn is intended to improve impregnating properties by pulverizing a thermoplastic resin and sprinkling it on reinforcing fibers, but the adhesion of resin powder becomes uneven, making it difficult to control it. Is a problem. Further, the workability is poor because the resin powder spills out. To prevent this, a material has been developed in which the workability is improved by covering with a shell made of the same resin as the resin powder.

　次にカミングレッドヤーンは２種類の繊維を混織したもので、含浸性には優れているが、強化繊維と、マトリックス樹脂を混織する技術を完成するには、該ヤーンの製造工程で繊維の損傷度をいかに低くするか、特性の大きく異なる繊維をいかにそれぞれ同時に分散し均一に混合するかという問題を解決しなければならない。特に炭素繊維を強化繊維とするカミングレッドヤーンの作製時は、炭素繊維の損傷が顕著であり、繊維の損傷をなくし、また炭素繊維とマトリックス繊維を分散させ均一に混合するには高度な技術を必要とすることも問題点となっている。 Next, the cumming red yarn is a mixture of two types of fibers, and is excellent in impregnation. However, in order to complete the technique of mixing the reinforcing fiber and the matrix resin, it is necessary to use a fiber in the yarn manufacturing process. The problem must be solved how to reduce the degree of damage to fibers and how to simultaneously disperse and uniformly mix fibers having greatly different properties. Especially when producing cumming red yarn using carbon fiber as a reinforcing fiber, the damage to the carbon fiber is remarkable, and advanced technology is required to eliminate the fiber damage and to disperse and uniformly mix the carbon fiber and the matrix fiber. The need is also a problem.

　この発明は、複数本の熱可塑性合成樹脂繊維よりなる編組繊維中に強化繊維を挿入した複合強化繊維を利用した材料、並びにこの繊維に使用した板材などを得ることにより、前記従来の問題点を解決したのである。 The present invention solves the above-mentioned conventional problems by obtaining a material using a composite reinforced fiber in which a reinforcing fiber is inserted into a braided fiber composed of a plurality of thermoplastic synthetic resin fibers, and a plate material used for the fiber. It was resolved.

　即ちこの発明は、複数本の合成樹脂繊維と、熱融着性合成樹脂繊維の単独又は両方の編組織繊維中に、単数又は複数の強化繊維を長手方向に挿入した複合強化原糸を縦糸及び／又は横糸に使用して編網し、前記縦糸と横糸の交叉部を接着又は熱融着固定したことを特徴とする複合強化原糸を用いた編成物であり、強化繊維は、アラミド繊維、ガラス繊維、セラミック繊維、炭素繊維、又は超高分子量ポリエチレン繊維としたことを特徴とするものであり、熱融着性合成樹脂繊維は、熱融着性に優れたポリアミド、ポリスチール、ポリプロピレン、ポリアセタール、ポリカーボネート、ポリエチレン樹脂繊維としたことを特徴とするものである。 That is, the present invention provides a warp and a composite reinforced raw yarn in which one or a plurality of reinforcing fibers are inserted in a longitudinal direction into a plurality of synthetic resin fibers and a single or both knitted tissue fibers of a heat-fusible synthetic resin fiber. And / or knitting by using a weft, and a knitted fabric using a composite reinforced raw yarn characterized in that an intersection of the warp and the weft is bonded or heat-fused, and the reinforcing fiber is an aramid fiber; Glass fiber, ceramic fiber, carbon fiber, or ultra-high molecular weight polyethylene fiber, characterized by heat-fusible synthetic resin fiber, heat-sealable polyamide, polysteel, polypropylene, polyacetal , Polycarbonate and polyethylene resin fibers.

　前記発明において使用する原糸は、この発明に使用する新規な強化繊維入りの糸であって、この発明の編組材の構成材であり、構造材などの補強材として使用する。 The raw yarn used in the above invention is a yarn containing the novel reinforcing fiber used in the present invention, and is a constituent material of the braided material of the present invention, and is used as a reinforcing material such as a structural material.

　前記原糸は、そのままでは相互間の接着性が小さいので、融着性合成樹脂を組み込み、又は熱融着性合成樹脂を付着させることにより、この発明の原糸を使用した編組材等の一体化を向上させたものである。 Since the raw yarns have little adhesiveness to each other as they are, a fusible synthetic resin is incorporated, or a heat fusible synthetic resin is adhered to the raw yarn to form a braided material using the raw yarn of the present invention. It is one that has been improved.

　前記融着性合成樹脂としては、例えばチーグラー糸又はフィリップス糸触媒を用いて重合し、触媒除去工程を経ずに製造された熱融着性に優れたポリエチレン樹脂繊維など（特開平４−２９３９４４号）が知られているが、これに限定されるものではない。要は複合強化繊維及び他の繊維との親和性があって、加熱接着強度の大きい材質が使用される。 As the fusible synthetic resin, for example, a polyethylene resin fiber having excellent heat fusibility produced by polymerization using a Ziegler yarn or Phillips yarn catalyst and without passing through a catalyst removing step (Japanese Patent Laid-Open No. 4-293944). ) Is known, but is not limited thereto. In short, a material having an affinity for the composite reinforcing fiber and other fibers and having a high heat bonding strength is used.

　前記編網又は織成に際しては、例えば縦原糸と横原糸の一方又は両方に熱融着糸を入れて、縦原糸と横原糸の交差部を熱融着する。この場合に、全網又は織布を加熱すると、交差部以外の原糸も熱融着するので、網体又は織布などの剛性が向上し、取扱いが容易になるのみならず、構造体に介装した際に所定の位置を正しく保つことができる。 編 In the knitting or weaving, for example, a heat fusion yarn is inserted into one or both of the warp yarn and the weft yarn, and the intersection of the warp yarn and the weft yarn is heat fused. In this case, when the whole net or the woven fabric is heated, the yarns other than the intersections are also heat-sealed, so that the rigidity of the net or the woven fabric is improved, and not only the handling becomes easy but also the structure becomes When interposed, a predetermined position can be correctly maintained.

　前記における熱融着糸を編入することなく、各原糸に熱融着性樹脂粉末を付着させ、又は被覆し、或いは噴霧するなどの手段も考えられるが、用途に応じ適宜選定使用する。 手段 Means of adhering, coating, or spraying a heat-fusible resin powder on each raw yarn without knitting the heat-fusible yarn in the above can be considered, but they are appropriately selected and used according to the application.

　前記発明において、合成樹脂繊維の中央糸又は中心糸として強化繊維を長手方向に挿入することは従来の機械により容易に達成できる。また前記強化繊維入りの合成樹脂繊維を複数本編組（捩り合せ、その他）することも従来公知の機械を使用することにより達成することができるが、複合強化繊維としての提案はない。 In the above invention, the insertion of the reinforcing fibers in the longitudinal direction as the center yarn or the center yarn of the synthetic resin fibers can be easily achieved by a conventional machine. The braiding (twisting, etc.) of a plurality of the synthetic resin fibers containing the reinforcing fibers can also be achieved by using a conventionally known machine, but there is no proposal as a composite reinforcing fiber.

　前記編組時に、強化合成樹脂繊維のみを使用し、又は普通の合成樹脂繊維と強化合成樹脂を使用し、更に合成樹脂繊維の編組時に、その中央糸又は中心糸として比較的直径の大きい強化繊維を編み込むことも従来の機械により容易に実施することができる。 At the time of braiding, use only reinforced synthetic resin fibers, or use ordinary synthetic resin fibers and reinforced synthetic resin, and further, at the time of braiding of synthetic resin fibers, use reinforcing fibers having a relatively large diameter as a central yarn or a central yarn thereof. Weaving can also be easily performed with conventional machines.

　前記発明の繊維を、前記発明の材料にするには、従来知られている編機を使用することが出来るが、この発明の繊維は大径であるから、前記編機の各部寸法を大径の繊維に適合すべく改善しなければならない。 In order to make the fiber of the invention into a material of the invention, a conventionally known knitting machine can be used, but since the fiber of the invention has a large diameter, the dimensions of each part of the knitting machine are set to a large diameter. Have to be improved to fit the fiber.

　前記発明において、中央糸とは、複数本の繊維を編組した組糸の中に挿入される糸をいう。また中心糸とは、丸打組物の芯となり、又は撚糸状にカバリングされた紐の芯となり、周りに組物が形成されるように芯として挿入する糸をいう。 に お い て In the invention, the central yarn refers to a yarn inserted into a braided yarn obtained by braiding a plurality of fibers. The center yarn is a yarn inserted as a core so as to form a core of a round braid or a core of a cord covered in a twisted form and form a braid around the core.

　従って図１の（ａ）、（ｂ）、（ｃ）は中央糸の例であり、図１の（ｄ）は中心糸の例である。何れにしても中央糸と中心糸は、丸打組機などにより、編組する際に入れることができる。 Therefore, FIGS. 1A, 1B, and 1C are examples of the center yarn, and FIG. 1D is an example of the center yarn. In any case, the center yarn and the center yarn can be inserted at the time of braiding by a round driving machine or the like.

　この発明における強化繊維は、前記中央糸又は中心糸の他に、他の繊維束と共に撚り合せて紐とする場合もある。 強化 The reinforcing fiber in the present invention may be twisted together with another fiber bundle in addition to the center yarn or the center yarn to form a string.

　前記発明における複数の合成樹脂繊維は、同一種の合成樹脂繊維でも、異種の合成樹脂繊維でもよく、強化繊維との組合せについても原則として制約はない。要するに材質の選択と組合せは自由である。 複数 The plurality of synthetic resin fibers in the invention may be the same kind of synthetic resin fibers or different kinds of synthetic resin fibers, and there is no restriction in principle on the combination with the reinforcing fibers. In short, selection and combination of materials are free.

　この発明の材料は、ボード等船舶のボディー、バス、トラック、列車輌等のボディー、コンテナー、スノーボード、サーフィンボード、スキー板、自動車のフロアパネル及びサイドドア、風車の羽根、航空機の胴体、海底油田基地のフレーム、橋脚の補強材など、各種板材であって、従来熱硬化性板として使用されていた板材に使用することができる。 The materials of the present invention include bodies of ships such as boards, bodies of buses, trucks, trains, etc., containers, snowboards, surfboards, skis, floor panels and side doors of automobiles, blades of windmills, fuselage of aircraft, offshore oil fields. It can be used for various plate materials such as a base frame, a bridge pier reinforcing material, and the like, which has been conventionally used as a thermosetting plate.

　この発明の原糸を用いて編組した編体又は織布は、各種構造材の補強材（例えば鉄筋又は金網、パンチングメタルなど）として使用することができる。 編 The braided or woven fabric braided using the yarn of the present invention can be used as a reinforcing material for various structural materials (for example, a reinforcing bar or a wire mesh, a punching metal, or the like).

　特に軽量であり（比重１前後）引張強度が大きく、構造材（例えばセメントモルタル）との接着性も良好であり、耐候性、耐化学性も大きいので、建材はもとより、コンクリート建造物の補強にも有効である。 It is particularly lightweight (approximately 1 specific gravity), has high tensile strength, good adhesion to structural materials (for example, cement mortar), and has high weather resistance and chemical resistance, so it can be used not only for building materials but also for reinforcing concrete buildings. Is also effective.

　然して繊維層を多層にすれば、所望の強度に成形できるので、目的と強度に合致した板材とすることができる。 Naturally, if the fiber layer is formed into a multilayer, it can be formed to a desired strength, and a plate material that meets the purpose and strength can be obtained.

　この発明は、複数本の合成樹脂繊維よりなる編組繊維中に強化繊維を長手方向に挿入したので、きわめて強靭な複合強化繊維となるので、この複合強化繊維を用い網状物又は布状物に編成し、加熱溶融して一体化するので、この網状物又は布状物をそのまま使用し（例えば脆弱法面被覆）、又は土中、コンクリート中に埋設して使用すれば、補強力は抜群であって、土木工事、建材その他各種構造材として、きわめて優れている。 According to the present invention, since the reinforcing fibers are inserted in the longitudinal direction into the braided fibers composed of a plurality of synthetic resin fibers, the composite reinforcing fibers become extremely tough. Therefore, the composite reinforcing fibers are knitted into a net or cloth using the composite reinforcing fibers. If the mesh or cloth is used as it is (for example, fragile slope covering) or buried in soil or concrete, the reinforcing power is excellent. It is extremely excellent as a civil engineering work, a building material and other various structural materials.

　前記複合強化繊維は外側が合成樹脂であるから、編組材を加熱することによって、当接部が融着するので、従来行われていたような編組後の合成樹脂含浸作業は不必要になる効果がある。 Since the outside of the reinforced composite fiber is a synthetic resin, the abutting portion is fused by heating the braided material, so that the synthetic resin impregnation work after braiding, which has been conventionally performed, becomes unnecessary. There is.

　この発明は熱可塑性合成樹脂繊維よりなる編組繊維中に強化繊維を長手方向に挿入（強化繊維を中央糸又は中心糸とし、又は撚り込む）した原糸である。また前記原糸に熱融着性合成樹脂繊維を編組した複合強化原糸である。前記複合強化原糸を用いた編成物である。 発 明 The present invention is a raw yarn in which reinforcing fibers are inserted in the longitudinal direction into braided fibers made of thermoplastic synthetic resin fibers (the reinforcing fibers are used as a central yarn or a central yarn or twisted). Further, the present invention is a composite reinforced yarn obtained by braiding heat-fusible synthetic resin fibers to the yarn. It is a knit using the composite reinforced yarn.

　この発明は、合成樹脂繊維の編組して、そのままへ強化繊維を長手方向に挿入したので、熱可塑性合成樹脂であっても、含浸性が改善され、一体化することができる。 According to the present invention, the reinforcing fiber is braided into the synthetic resin fiber, and the reinforcing fiber is inserted in the longitudinal direction as it is. Therefore, even if the synthetic resin is a thermoplastic synthetic resin, the impregnation property is improved and the resin can be integrated.

　また強化繊維としては、アラミド繊維、ガラス繊維、セラミック繊維、炭素繊維、又は超高分子量ポリエチレン繊維などである。 The reinforcing fibers include aramid fibers, glass fibers, ceramic fibers, carbon fibers, and ultra-high molecular weight polyethylene fibers.

　また合成樹脂繊維としては、ＰＥＥＫ繊維、アクリル繊維、ナイロン繊維、ポリウレタン繊維、ポリエチレン繊維、ポリプロピレン繊維、又はレーヨンなどである。 (4) Examples of the synthetic resin fiber include PEEK fiber, acrylic fiber, nylon fiber, polyurethane fiber, polyethylene fiber, polypropylene fiber, and rayon.

　前記繊維の複数本を丸打組機で編組するか、又はカバリングヤーン中に強化繊維を中央糸又は中心糸として組み込み一体化した組糸とし、又は撚り糸の繊維の一つとして強化繊維を用いる。 複数 A plurality of the above fibers are braided by a round driving machine, or a reinforcing fiber is incorporated as a central yarn or a central yarn into a covering yarn to form an integrated braid, or a reinforcing fiber is used as one of the twisted yarn fibers.

　この発明で使用するマイクロブレイデッドヤーン（Micro-braided yarn 、以下Ｍ．ｂ．ｙという）を図１、２に基づいて説明する。このＭ．ｂ．ｙは、図１（ａ）のように、ガラス繊維束１の５本と、ＰＡ６繊維束２の８本よりなる組紐３（タイプＭ５）である。前記各繊維束は、夫々４０〜６０本のフィラメントを束ねたものである。また図１（ｂ）は、ガラス繊維束１の４本と、ＰＡ６繊維束２の８本よりなる組紐４（タイプＭ）である。次に図１（ｃ）は、ガラス繊維束１の２本と、ＰＡ６繊維束２の８本よりなる組紐５（タイプＳ）である。更に図１（ｄ）は、ガラス繊維束１の１本（中心部へ太く）入っており、組紐６（タイプＡ）である。 (1) A micro-braided yarn (hereinafter, referred to as Mby) used in the present invention will be described with reference to FIGS.

The impregnation distance is the maximum distance that the matrix resin travels to impregnate the fiber bundle, and in the above-described embodiment, it is the radius of the reinforcing fiber bundle.
