摘　　要：研究了碳纤维 铜 石墨复合材料在纯机械磨损和电磨损条件下 ,电刷压力的变化 ( 7 5～ 30N/cm2 )对复合材料电刷摩擦系数的影响 ,用扫描电镜观察了磨面形貌 ,对复合材料摩擦系数的变化机理进行了初步探讨。Under no current and 15 A/cm 2 conditions, the influences of different brush pressure(7.5 ～30 N/cm 2) on the friction coefficients of CF Cu G composite were studied. The friction coefficient under mechanical wear was larger than that under electrical wear. The results show that the friction coefficient of composite decreased due to the lubricant film. The friction coefficient was minimal under 15 N/cm 2 pressure, and the friction coefficient increased with increasing or decreasing pressure.
