复合材料复合材料是由两种或两种以上性质不同的材料组合而成。不同的非金属材料可以相互复合,非金属材料可以与各种不同金属材料复合,不同金属材料也可以相互复合。复合材料的特点是比强度大,比模量大,化学稳定性好,耐磨性好,自润滑性好,隔热性、耐烧蚀性以及特殊的电、光、磁性均好。根据基体材料的不同,复合材料可分为金属基复合材料和非金属基复合材料。复合材料的发展分为三个阶段:第一阶段(第一代复合材料)是四十年代开始研制的玻璃纤维增强塑料复合材料;第二阶段(第二代复合材料)是六十年代开始研制的一种碳纤维增强塑料新型复合材料;第三阶段(第三代
Composites Composites are made of two or more materials of different qualities. Different non-metallic materials can be combined with each other, non-metallic materials can be combined with a variety of different metallic materials, different metallic materials can also be combined with each other. Composites are characterized by specific strength, specific modulus, chemical stability, good wear resistance, good self-lubricating, heat insulation, ablation resistance and special electrical, optical and magnetic are good. According to the different matrix materials, composite materials can be divided into metal matrix composites and non-metal matrix composites. The development of composite materials is divided into three phases: the first phase (the first generation of composite materials) is a glass fiber reinforced plastic composite material developed in the forties; the second phase (second generation composite materials) started to be developed in the 1960s A new type of carbon fiber reinforced plastics composite materials; the third stage (third generation
