Description
本発明は、材料を可塑性の状態下で成型するものであり、特に高分子複合材料である拡繊織物の可塑性の状態下での成型に関するものである。 The present invention relates to molding a material in a plastic state, and particularly to molding a expanded fiber woven fabric, which is a polymer composite material, in a plastic state.
従来の熱硬化拡繊紗は、製造過程中に用いられる熱硬化高分子予浸材における熱硬化性樹脂が常温状態で粘り気があることから、予浸材を巻き取る際にべとつくことを防ぐため、表面に剥離シートで覆っておくので、後からこの予浸材を使用する時に、またその剥離シートを剥がす必要があり、さらに、引き続き製造過程中に熱硬化性樹脂が硬化することを防ぐために、低温状態に保持しなければならない。尚、この方法によれば、予浸材を加熱硬化させることから、べとつかなくなるものの、互いに直接に付着させることもできなくなることから、再度含浸させたり、可塑性材料を添加したりしなけらば積み重ねて加圧成形することができないので、生産性に不向きである。 In the conventional thermosetting expansion fiber, the thermosetting resin in the thermosetting polymer pre-soaking material used during the manufacturing process is sticky at room temperature, so that it is prevented from becoming sticky when the pre-soaking material is wound up. Since the surface is covered with a release sheet, it is necessary to remove the release sheet when using this pre-immersion material later, and further, in order to prevent the thermosetting resin from further curing during the manufacturing process. , Must be kept cold. According to this method, since the pre-immersion material is heat-cured, it becomes non-greasy, but it cannot be directly adhered to each other. Therefore, it must be impregnated again or a plastic material must be added for stacking. It is not suitable for productivity because it cannot be pressure molded.
また、従来の熱可塑性拡繊紗は、寸法の安定性に劣るので、生産に適していない。 In addition, conventional thermoplastic expanded fibers are not suitable for production because they are inferior in dimensional stability.
ほかにも、現在の業界では、幅がさらに広く厚さがさらに薄い拡繊紗の要望があるので、いかに拡繊織物の原料の厚さを薄く、幅を広くするかが現在の製造方法における課題であった。 In addition, in the current industry, there is a demand for a spreader gauze with a wider width and a thinner thickness, so how to make the raw material of the spread fabric thinner and wider is the current manufacturing method.

図５は、裁断された予浸材を設計によって製織した高分子複合材料の拡繊織物を示すものである。 FIG. 5 shows a expanded woven fabric of a polymer composite material in which a cut pre-immersion material is woven by design.
本発明に係る製造方法によって作られた高分子複合材料の拡繊織物は、拡繊紗により製織されるものであり、該拡繊紗は、以下に示す特徴を含む。つまり、複数本の繊維１０と基材２０とを含み、該複数本の繊維１０を単一方向に揃える。尚、前記各繊維は、炭素繊維やガラス繊維などの任意の強化繊維であってもよく、基材２０は熱可塑性樹脂である。また、該拡繊紗の目付け重量は、７０ｇ／ｍ２〜１６０ｇ／ｍ２であり、樹脂の含有量は、３０％〜５０％であり、幅は、１００ｃｍである。 The fiber-expanded woven fabric of the polymer composite material produced by the production method according to the present invention is woven by a fiber-expanding gauze, and the fiber-expanding gauze includes the following features. That is, the plurality of fibers 10 and the base material 20 are included, and the plurality of fibers 10 are aligned in a single direction. The fibers may be any reinforcing fibers such as carbon fibers and glass fibers, and the base material 20 is a thermoplastic resin. Also, the basis weight by weight of the enlarged繊紗is 70g / m 2 ~160g / m 2 , the content of the resin is 30% to 50%, width is 100 cm.
より好ましくは、前記拡繊紗の目付け重量が７０ｇ／ｍ２〜１６０ｇ／ｍ２であり、樹脂の含有量が３２％〜４７％であり、この状態で作られた製品は、予浸材の厚さを最も有効に低減させることができると共に、安定した歩留まりが得られるので、本発明に係る高分子複合材料の拡繊織物の品質を向上させることができる。 More preferably, basis weight weight of the fiber spreading gauze is is 70g / m 2 ~160g / m 2 , a 32% to 47% content of the resin, products made in this state, the pre-soaked material Since the thickness can be reduced most effectively and a stable yield can be obtained, the quality of the expanded woven fabric of the polymer composite material according to the present invention can be improved.
本発明に係る拡繊紗が低い目付け重量と低い樹脂の含有量の特徴を持つことで、厚さを低減させると共に、幅を広げることができるので、この拡繊紗を使って製織された高分子複合材料の拡繊織物は、厚さをより薄くする目的を達成できる。 Since the expanded fiber gauze according to the present invention has the characteristics of low basis weight and low resin content, the thickness can be reduced and the width can be widened.

熱硬化高分子化合物を基材とする予浸材は、常温下の樹脂がべたつく問題を防ぐため、剥離シートを使用する必要があり、また、低温環境を維持しながら引き続き製造工程を行う面倒もある。それに比べ、本発明は、熱可塑性高分子化合物を予浸材の基材とするが、予浸材は定型ステップで焼いた後すでに乾燥の状態となっていることから、べたつかないので、裁断作業がしやすく、更に、その後の工程においても、常温で生産することができることから、材料が取り扱いやすく、作業効率を高められるので、製造コストの低減を達成できる。 For pre-immersion materials based on thermosetting polymer compounds, it is necessary to use a release sheet to prevent the problem of stickiness of the resin at room temperature, and it is also troublesome to continue the manufacturing process while maintaining a low temperature environment. is there. In comparison, in the present invention, the thermoplastic polymer compound is used as the base material of the pre-immersion material, but since the pre-immersion material is already in a dry state after being baked in the standard step, it is not sticky, so the cutting operation is performed. Since it is easy to remove and can be produced at room temperature even in the subsequent process, the material is easy to handle and the work efficiency can be improved, so that the manufacturing cost can be reduced.
本発明に係る高分子複合材料の拡繊織物を製造する時は、異なる方向の応力要求に応じて、複数枚の予浸材を所要の異なる角度に積み重ねて加圧してから裁断および製織し、それによれば、従来技術と比べると、再度含浸したり、可塑性材料を添加したりする必要がなく、完成後、短時間加熱するだけで定型させることができると共に、織物の図柄を維持することもできるので、製織における設計自由度や作業の利便性を向上させることができる。 When producing a expanded woven fabric of a polymer composite material according to the present invention, a plurality of pre-soaking materials are stacked at different required angles, pressed, and then cut and woven in response to stress requirements in different directions. According to this, as compared with the prior art, there is no need to re-impregnate or add a plastic material, and after completion, it can be stylized by heating for a short time, and the pattern of the woven fabric can be maintained. Therefore, it is possible to improve the degree of freedom in designing and the convenience of work in weaving.
拡繊ステップＳ１においては、単一方向に揃えた強化繊維に対して拡繊作業を行い、それぞれの繊維を拡繊する際に、隣接する繊維同士を当接させて互いの移動を制限することで、拡繊された製品の幅と目付け重量を均一とし、製織された本発明の高分子複合材料の拡繊織物の厚を調整可能とする。 In the fiber expanding step S1, the reinforcing fibers aligned in a single direction are expanded, and when the respective fibers are expanded, the adjacent fibers are brought into contact with each other to limit their movement. Therefore, the width and the weight of the expanded product can be made uniform, and the thickness of the woven polymer composite material of the present invention can be adjusted.
含浸ステップＳ２において、拡繊された繊維を、熱可塑性高分子化合物である基材の内に均一に含浸させて、高分子複合材料の拡繊織物を得る。 In the impregnation step S2, the expanded fibers are uniformly impregnated into the base material which is a thermoplastic polymer compound to obtain a expanded woven fabric of a polymer composite material.
本発明は、前述した製造方法の改善によって完成させた高分子複合材料の予浸材の幅は、１００ｃｍとすることが可能であることから、裁断時に、より多く本数の帯状の拡繊紗が得られる。故に、高分子複合材料の拡繊織物の生産量を増やせる上、裁断時における繊維の保全性を高め、誤差を低減させることができるので、高分子複合材料の拡繊織物の品質向上を図ることができる。 In the present invention, the width of the pre-soaking material of the polymer composite material completed by the improvement of the manufacturing method described above can be 100 cm, so that a larger number of strip-shaped expanding fibers can be formed at the time of cutting. can get. Therefore, it is possible to increase the production amount of the expanded woven fabric of the polymer composite material, improve the preservation of the fiber at the time of cutting, and reduce the error. Therefore, it is possible to improve the quality of the expanded woven fabric of the polymer composite material. Can be done.
