ET), polyphenylene sulfide (PPS), aromatic polyamide (aromatic PA) and the like are used, and furthermore, polyether sulfone (PES) and polyether ether ketone (PEEK) which are engineering plastics having excellent heat resistance are used. . As the reinforcing fiber, for example, glass fiber is used. The diameter of the glass fiber used is usually 3 to 15 μm, preferably 6 to 10 μm in consideration of the reinforcing effect and the aggressiveness to the mating member.
μm, preferably about 6 μm. If the diameter of the glass fiber exceeds 15 μm, the smoothness of the surface is impaired, and the aggressiveness to the counterpart member increases. If the diameter is less than 3 μm, cohesion between the fibers occurs and uniform dispersion is difficult, and the reinforcing effect is reduced. It is because it becomes less. The content of the reinforcing fibers is 5 to 30% by weight, preferably 5 to 15% by weight. When the content of the reinforcing fiber is less than 5% by weight, the abrasion of the resin base material progresses and the reinforcing effect cannot be obtained, and when it exceeds 30% by weight, the fluidity deteriorates and the surface smoothness is impaired. .
