摘　　要：利用真空热压烧结技术制备了不同碳纤含量的碳纤维/聚醚醚酮(CF/PEEK)复合材料,采用热导率分析仪和热重测试仪对材料的热学性能进行表征,并利用多功能摩擦磨损试验机、三维形貌轮廓仪、扫描电子显微镜和摩擦静电计对材料的摩擦磨损性能和抗摩擦静电性能进行分析。分析结果表明:随着CF添加量的增加,复合材料摩擦因数、磨损率和摩擦静电电压先降低后升高,当CF添加量(质量分数)为20%时,摩擦因数、磨损率和摩擦静电电压达到最低,分别为0.247、5.6×10^(-6)mm/(N·m)和3.3 V,证明此种方法制备的20%CF/PEEK材料具有优异的摩擦磨损性能和抗静电性能。CF/PEEK复合材料磨损机理以黏着磨损为主,并且伴随着轻微的磨粒磨损。CF/PEEK composites were prepared by vacuum hot pressing sintering technology.The thermal properties of the materials were tested by thermal conductivity analyzer and TG tester.Multifunctional friction and wear testing machine,3D morphology profilometer,scanning electron microscope and friction electrometer were used to analyze the friction and wear properties and anti-friction electrostatic properties of the materials.The results show that with the increase of the forming temperature,the friction coefficient and wear rate of the materials decrease gradually.With the increase of CF contents,the friction coefficient,wear rate and friction electrostatic voltage decrease first and then increase.When the CF content is as 20%,the friction coefficient,wear rate and friction electrostatic voltage reach the lowest values,which are as 0.247,5.6×10^(-6)mm/(N·m)and 3.3 V,respectively.Friction and electrostatic data show that the CF/PEEK materials prepared by this method have better friction properties and anti-electrostatic properties than that of commercial composites.The wear mechanism of CF/PEEK composites is mainly adhesive wear,accompanied by slight abrasive wear.
