産業上の利用分野
本考案は、複合材料の強化材として使用される
バイアスクロスに関するものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a bias cloth used as a reinforcing material for composite materials.
バイアスクロスは糸条が斜めに延びているた
め、長さ方向及び幅方向に極めて伸び易く、取扱
い中に歪が生じ易い。従つてその取扱い性を向上
させるため、特にバイアスクロスの長さ方向の伸
びを止める必要がある。 Since bias cloth has threads extending diagonally, it is extremely easy to stretch in the length direction and width direction, and is easily distorted during handling. Therefore, in order to improve its handling properties, it is necessary to stop the bias cloth from elongating, especially in the longitudinal direction.

この目的のための手段として、特開昭58−
41949号公報に記載されたものが知られている。

のである。Prior art As a means for this purpose,
The one described in Publication No. 41949 is known.
This is a bias cloth reinforced with glass fiber staple threads or rappet threads in the length direction.

自体屈曲しているので、バイアスクロスに力がか
かつたときに伸縮し易く、バイアスクロスの寸法
安定性が良好とは言えない。Problems to be Solved by the Invention However, since the staple yarn and rappet yarn are themselves bent, they tend to expand and contract when force is applied to the bias cloth, and the dimensional stability of the bias cloth cannot be said to be good.

部的に伸びたり切れたりし易く、バイアスの角度
が変化したりクロスに歪みが生じて凹凸になり、
加工が困難になると共に、複合材料として強度が
不十分となる。 Furthermore, since glass fiber is brittle and has a small hook, it easily breaks when force is applied to the bias cloth. In addition, since glass fibers have low elongation, even slight differences in the tension of the staple threads or rappet threads can easily cause local elongation or breakage, causing the bias angle to change and the cloth to become distorted, resulting in unevenness.
Processing becomes difficult and the strength as a composite material becomes insufficient.
本考案はかかる事情に鑑みなされたものであつ
て、寸法安定性が良く、複合材料の強化材として
適したバイアスクロスを提供することを目的とす
るものである。 The present invention was devised in view of the above circumstances, and it is an object of the present invention to provide a bias cloth that has good dimensional stability and is suitable as a reinforcing material for composite materials.

のである。Means for Solving the Problems The present invention provides a bias cloth made by diagonally crossing threads made of high-strength fibers, and a reinforcing thread made of high-strength fibers extending in the length direction of the bias cloth, on at least one side of the bias cloth. The invention is characterized in that the reinforcing thread is sewn to the bias cloth with a suture thread extending diagonally along the bias cloth.

の高強度繊維よりなる糸条２を斜めに交差させて
構成している。 The drawing shows a bias cloth 1 of the present invention, which is constructed by diagonally crossing threads 2 made of high-strength fibers such as carbon fibers, glass fibers, and aramid fibers.

しても良い。 On the surface of the bias cloth 1, a plurality of reinforcing threads 3 are arranged in parallel along the length direction of the bias cloth 1. The reinforcing thread 3 is made of high-strength fiber and must be disposed on at least one side of the bias cloth 1, but may be disposed on both sides.

ものである。 This reinforcing thread 3 is sewn to the bias cloth 1 with a suture thread 4. Although the material of the suture thread 4 is not particularly limited, it is preferable to use the above-mentioned high-strength fibers. The suture thread 4 is then diagonally sewn into the bias cloth 1, and the reinforcing thread 3 is sewn onto the bias cloth 1 using the suture thread 4.
作 用

に阻止することができる。Function: In the present invention, the reinforcing yarn 3 prevents the bias cloth 1 from elongating in the length direction. Since this reinforcing thread 3 is not bent and is arranged linearly along the surface of the bias cloth 1, there is no expansion or contraction due to bending and elongation as in the conventional example, and there is no decrease in strength due to bending. Thus, the bias cloth 1 can be reliably prevented from elongating.

１に伸びや歪が生じることがなく、寸法安定性に
優れたものとなる。 Furthermore, since the reinforcing thread 3 is sewn to the bias cloth 1 using the suture thread 4, the reinforcing thread 3 can be securely fixed to the bias cloth 1, and the reinforcing thread 3 will not be bent. Furthermore, since the tension of the reinforcing threads 3 is uniform, the bias cloth 1 does not undergo elongation or distortion, resulting in excellent dimensional stability.

とがなく、取扱い性に優れている。Effects of the invention Therefore, according to the invention, the dimensional stability of the bias cloth 1 is extremely excellent. Therefore, when this bias cloth 1 is wound into a coil, when it is unwound and cut into a predetermined shape, and when it is combined with a synthetic resin to form a composite material,
Even when force is applied to the bias cross 1, no distortion occurs, and the handleability is excellent.
従つて複合材料の成形が容易であると共に、当
