摘　　要：采用传统粉末冶金工艺制备了碳纳米管增强树脂/石墨复合材料,并加工成电机碳刷,研究了碳纳米管的加入对树脂/石墨碳刷静态和动态性能的影响。结果表明:碳纳米管的加入提高了树脂-石墨碳刷的弯曲强度和硬度,降低了碳刷的电阻率。碳纳米管的加入减小了树脂/石墨碳刷的摩擦系数和磨损率,提高了碳刷的使用寿命。The CNTs reinforced resin/graphtie composites were fabricated by powder metallurgy, and processed into carbon brush. The effects of CNTs on static and dynamic properties of composites were studied. The results show that the CNTs increase the flexural and hardness of composites, and decrease the resistivity. The addition of CNTs decreases the fric- tion coefficient, wear value and increase the life of the resin-graphite brush.
