摘　　要：研究了碳纤维表面预处理和化学镀铜工艺,采用正交设计方法对碳纤维镀铜工艺进行优化,并对制备的镀铜碳纤维进行SEM和XRD微观表征。在镀铜碳纤维中加入PTFE制备固体润滑复合材料,并进行摩擦磨损实验。实验结果表明:碳纤维表面有C==O及C—O—C等极性基团,能与铜产生较好的机械结合力;经过解胶、还原等表面处理后,碳纤维表面形成凹槽和微孔,便于化学镀时铜附着在其表面;化学镀后铜与碳纤维结合紧密,碳纤维表面镀层光亮、均匀致密、具有较好的结合力;采用化学镀原料配比CuSO4.5H2O15g/L,EDTA25g/L,NaOH16g/L制得的镀铜碳纤维,其镀铜量居中,加入PTFE所制得的固体润滑材料摩擦因数和磨损量较低,且摩擦因数有下降的趋势。The surface treatment methods of carbon fiber and the intluencing lactors during electroless plating process were studied. The process of electroless plating on carbon fiber surface was optimized by orthogonal experimental design. The surface of the copperized carbon fiber was analyzed by scanning electron microscopy （ SEM ） and X-ray diffraction （XRD）, the friction and wear properties were studied by adding the prepared copperized carbon fiber to PTFE to form solid lubricating composite materials. The results indicate that, with polar groups on the surface, such as C = O, C--O--C and so on, the carbon fiber has better mechanical binding force with Cu. The flute and micro pore is formed on the surface of carbon fiber after the surface disposal of removing glue and deoxidize, so the copper is easily plated on the surface of carbon fiber. Copper coating formed on surface of carbon fiber is bright, uniform, dense and of good adhesion to the fiber. The copperized carbon fiber prepared with the formula of CuSO4 ·5H2O 15 g/L, EDTA 25 g/L, NaOH 16 g/L has moderate copper layer, after adding PTFE, the prepared solid lubricant has low friction coefficient and wear mass loss, and the friction coefficient has a trend of decrease during friction.
