産業上の利用分野
この発明は、繊維で強化された、いわゆる強化
プラスチツク材に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to so-called reinforced plastic materials reinforced with fibers.
従来の技術及びその問題点
従来の代表的な強化プラスチツク材としては、
強化繊維として炭素繊維又はアラミド繊維のいず
れかを単独で網目状ではなく一方向にのみ繊維を
配置し、これを何層かに繊維の角度を変えて重ね
合わせ、エポキシ樹脂の母材で固めて成形したも
のが知られている。Conventional technology and its problems Typical conventional reinforced plastic materials include:
Either carbon fiber or aramid fiber is used as the reinforcing fiber, and the fibers are arranged only in one direction rather than in a mesh pattern, and these are stacked in several layers with the fibers changing the angle, and then hardened with an epoxy resin base material. Molded products are known.
その他の強化プラスチツク材としては、炭素繊
維とアラミド繊維を網目状に編み、これを何枚か
重ね合わせてエポキシ樹脂等の母材により固めて
成形するものも知られている。 Other reinforced plastic materials are also known, which are made by knitting carbon fibers and aramid fibers into a mesh shape, stacking several layers and hardening them with a base material such as epoxy resin.
以上いずれも、炭素繊維、アラミド繊維等を複
合或は単独で母材の中に積層挿入することによ
り、母材のプラスチツクを強化しているわけであ
る。 In all of the above, the plastic base material is reinforced by laminating and inserting carbon fiber, aramid fiber, etc. into the base material in combination or singly.
ところが、従来の強化プラスチツク材には次の
ような欠点がある。 However, conventional reinforced plastic materials have the following drawbacks.
すなわち、繊維の横方向に対する剪断及び繊維
と直角方向の引張りに対する強度がいずれも弱
い。これは、複合材としての強度ではなく、母材
だけの強度しかないことを意味する。 That is, the strength against shearing in the transverse direction of the fibers and the tensile strength in the direction perpendicular to the fibers are both low. This means that it does not have the strength of a composite material, but only the strength of the base material.
また、曲げに対して弱く、剥離しやすい欠点が
ある。 It also has the disadvantage of being weak against bending and easily peeling off.
そして、プレス等で打ち抜いた場合、眉間の剥
離が顕著に現れる。 When punched out using a press or the like, peeling between the eyebrows becomes noticeable.
以上の欠点は、層間の結びつき（層間強度）が
弱く、充分でないことを意味するものである。 The above drawbacks mean that the bond between the layers (interlayer strength) is weak and insufficient.
この発明は、従来の強化プラスチツク材の強さ
にプラスして層間の結びつき（層間強度）も大幅
に向上させることのできる強化プラスチツク材を
提供することを目的とするものである。 It is an object of the present invention to provide a reinforced plastic material that can significantly improve the bond between layers (interlaminar strength) in addition to the strength of conventional reinforced plastic materials.

等の樹脂（プラスチツク）の母材で固めたもので
ある。Means and Effects for Solving the Problems Firstly, the reinforced plastic material of the present invention consists of overlapping carbon fibers and/or aramid fibers knitted together in a mesh shape (if the meshes are woven at different angles, the effect can be improved). ), potassium titanate, silicon nitride, etc., or whisker-like short fibers with a length of 3 mm or less are mixed into a matrix of resin (plastic) such as epoxy or polyester.
これにより母材に混入したウイスカー又はウイ
スカーに類する長さ３mm以下の短繊維が三次元的
に分布し、網目の中にもウイスカー又はウイスカ
ーに類する長さ３mm以下の短繊維が侵入する。 As a result, whiskers or whisker-like short fibers with a length of 3 mm or less mixed in the base material are distributed three-dimensionally, and whiskers or whisker-like short fibers with a length of 3 mm or less also enter the mesh.
ウイスカー又はウイスカーに類する長さ３mm以
下の短繊維の作用により、母材と強化繊維の結び
つきが強固となり、材料そのものが非常に強化さ
れることになる。 Due to the action of whiskers or whisker-like short fibers with a length of 3 mm or less, the bond between the base material and the reinforcing fibers is strengthened, and the material itself is greatly strengthened.
固化（成形）は圧力だけ又は熱だけを加えるだ
けで可能であるが、圧力と熱の両方を加えるほう
が組織がより密になり望ましい。 Solidification (molding) can be achieved by applying only pressure or only heat, but it is preferable to apply both pressure and heat because the structure becomes denser.
圧力としては、10乃至300Kg／cm2程度、温度は
100℃乃至400℃程度で母材の種類により圧力と温
度は選ばれる。 The pressure is about 10 to 300Kg/ cm2 , and the temperature is about 10 to 300Kg/cm2.
The pressure and temperature are selected depending on the type of base material, ranging from about 100℃ to 400℃.

イスカー又はウイスカーに類する長さ３mm以下の
短繊維を混入させたエポキシ又はポリエステル等
の樹脂の母材で固めた（成形した）ものである。 By the way, in the case of the structure explained above, it is necessary to knit the mesh relatively coarsely (into the mesh there is a base material, a whisker, or a whisker-like material with a length of 3 mm).
It is difficult to handle and the homogeneous distribution of reinforcing fibers may be impaired. Therefore, the present invention provides a second
In addition, in addition to carbon fibers and/or aramid fibers, the same resin as the base material is made into thin fibers, and these materials are combined in a mesh shape. It is hardened (molded) with a base material of resin such as epoxy or polyester mixed with whiskers such as silicon or short fibers similar to whiskers with a length of 3 mm or less.
これにより、第１の場合と同様に、母材に混入

以下の短繊維が三次元的に分布し、網目の中にも
ウイスカー又はウイスカーに類する長さ３mm以下

強化繊維の結びつきが強固となり、材料そのもの
が非常に強化される。 As a result, as in the first case, whiskers or similar whiskers that are 3 mm in length are mixed into the base material.
The following short fibers are distributed three-dimensionally, and whiskers or whisker-like short fibers with a length of 3 mm or less penetrate into the mesh, and the action of the whiskers or whisker-like short fibers with a length of 3 mm or less causes the base material to The bond between the reinforcing fibers becomes stronger, and the material itself is greatly strengthened.
このように、第２の構成の場合はすでに母材が
網目の中（強化繊維の中）に入つているので、網
目を細かくしつかりと編んでも差支えないので、
繊維の均質な分布が取扱いにより損なわれること
がない。 In this way, in the case of the second configuration, the base material is already inside the mesh (inside the reinforcing fibers), so there is no problem even if the mesh is tightly knitted.
The homogeneous distribution of fibers is not impaired by handling.

層間強度が強化されるものである。 In other words, the same type of resin as the base material, which is woven into the mesh, is molded (at high temperature or high pressure).
(high pressure) melts and bonds with the base material, strengthening the bond between layers. In addition, whiskers or short fibers similar to whiskers with a length of 3 mm or less invade between the layers,
The interlaminar strength is strengthened.
