摘　　要：利用粉末冶金法制备Cf/C/Cu复合材料,通过改变碳纤维表面镀铜工艺条件,研究碳纤维表面镀铜对Cf/C/Cu复合材料组织及性能的影响。结果表明,碳纤维表面经浓硝酸处理再镀铜1 h,试样的动摩擦因数先增大后减小,至0.106后趋于不变,电阻率最低达0.12Ω.m。Carbon fiber-carbon-copper composite was prepared by powder metallurgy technique. Through changing preparation conditions of carbon fiber copper-coated, the influence of microstrueture and properties of Cf/C/Cu composite were studied. The results showed that after dense nitric acid treatment and 1 h copper-coated of carbon fiber, the friction coefficient of the samples increases firstly,then declines to 0. 106 ,and tends to be invariable finally;the lowest resistivity is 0.12 Ω·m.
