一、前言塑料和金属或陶瓷等比较,就大量生产性、成型性、轻质性等而言,是一种优异的材料。但是,塑料在弹性模量、强度方面因比上述两种材料低,所以,过去主要用作次级结构材料。近来由于出现玻璃纤维、碳纤维、硼纤维、Aramld纤维、碳化硅纤维等机械性能非常优异的新纤维,它们经过复合化处理,提高了被开发塑料复合材料的性能,从而使塑料材料能够被用作为一级结构材料。关于塑料复合材料的机械性能,根据复合规律,能够从增强剂和基材的特性,把它们提高到某种程度的设计指标。另一方面,关于塑料复合材料的摩擦、磨损性能,没有系统的研究。所以要给材料的广泛使 First, the preface Comparison of plastic and metal or ceramic, in terms of mass production, formability, lightness, etc., is an excellent material. However, plastics have been used mainly as secondary structural materials in the past due to their lower modulus of elasticity and lower strength than the above two materials. Recently, new fibers having excellent mechanical properties such as glass fiber, carbon fiber, boron fiber, Aramld fiber and silicon carbide fiber have been subjected to composite treatment to improve the performance of the developed plastic composite material so that the plastic material can be used as Primary structure material. Regarding the mechanical properties of plastic composites, according to the complex law, it is possible to raise them to some extent from the characteristics of the reinforcing agent and the substrate. On the other hand, there is no systematic study on the friction and wear properties of plastic composites. So give a wide range of materials
