りが生じ。It was processed by casting etc. However, in either case, the manufacturing process is complicated and production costs are high. Furthermore, during casting, defects due to internal pinholes sometimes resulted in defects. Also,
When cutting and punching metal, deformations such as burrs and twists occur due to processing distortion, and burrs occur at the punched part during punching.

、金属に比べ曲げ弾性率９曲げ強度が低く構造体として
用いた場合、変形を生じさせる原因となっていた。Therefore, the present inventors focused on plastic-fiber composite materials as a means to eliminate these drawbacks and reduce weight. However, in conventional plastic-fiber composite materials, the compatibility between the hydrophilic fibrous reinforcing agent and the lipophilic polymer is poor, and voids tend to form at their interfaces, making the material easily damaged by external heat, force, etc. Deformed. In addition, deformation, cracking, etc. occurred due to non-uniform internal stress distribution. In addition, when used as a structure, it has a lower flexural modulus of elasticity 9 than metal, which causes deformation.
本発明の目的とするところは、従来のプラスチック−繊

であれば良い。That is, the present inventors preferably use two types selected from the group consisting of polycarbonate, polysulfone, polyphenylene sagphite, olefin-vinyl alcohol copolymer, polyether sulfone, and acrylonitrile-styrene copolymer. A resin composition consisting of the above resin, a compound having an ethylenic double bond or an epoxy group, and a filler of at least 6 weight or more has excellent creep properties, 9 flexural modulus, 2 flexural strength, and dimensional stability. They discovered that this is a completely new resin composition that has not been found in conventional resin compositions. This composition chemically bonds the filler and polymer by adding a compound having an ethylenic double bond and/or an epoxy group to the mixture of the base polymer and filler, thereby improving their compatibility. This is what I did. Due to this improved compatibility, creep properties 1 bending stiffness 2 bending modulus 9
This resulted in improved dimensional stability. In the present invention, the resin mainly functions to bind the filler, and it is sufficient if the resin has a flexural modulus of 1s, ooo [Kg/d] or more. A chemical compound having an ethylenic double bond or an epoxy group has the effect of chemically bonding the resin and filler and making them compatible. The filler is glass fiber, 20
In the composition containing ~30% by weight, the average aspect ratio is 20 or more, or the filler is 20-30
Any glass peas with an average particle diameter of 63 μm or less may be used.

Table 6 JP-A-196250(4) The first characteristic is that the compound has at least 2 or more -1- functional groups, and as shown in the examples, it is impossible to achieve the effects of the present invention with compounds having <1 functional groups. In addition, the second feature is that by combining a fibrous filler such as glass fiber and a spherical filler such as glass beads, the ratio by weight is 1:1, which fully demonstrates the effects of each filler. If the ratio is outside this range, for example, if the ratio of fibrous filler increases, the cracks will increase, and if the spherical filler increases, the strength will decrease.

The functional groups of the superior compound contribute to the bonding between polymers and fins, or between polymers, resulting in an improvement in strength that has not been seen in conventional composite materials of this type. Also, due to this bonding, a reduction in voids and an improvement in adhesiveness were observed.
