摘　　要：通过粉末冶金方法,制备了镀铜碳纤维-石墨-铜基复合材料、碳纳米管-石墨-铜复合材料以及石墨-铜基复合材料,并通过对材料密度、电阻率、维氏硬度、抗弯强度的测试及显微组织的观察,比较了其综合性能。试验结果表明,碳纤维-石墨-铜基复合材料的各项性能明显优于其他两种铜基复合材料。Copper-coated carbon fiber-graphite-copper matrix composite,carbon nanotube-graphite-copper matrix composite and graphite-copper matrix composite were prepared by powder metallurgy.The properties of the composites,such as density,resistivity,Vickers hardness and bend strength,were tested,the microstructure is observed and then the comprehensive performance was compared with each other.The results show that carbon fiber-graphite-copper matrix composite is of the most excellent performance in the three composites.
