摘要(Abstract)：

通过真空热压烧结法制备了纯聚醚醚酮(PEEK)以及10%聚四氟乙烯/聚醚醚酮(PTFE/PEEK)复合材料，研究了PEEK及其复合材料在不同环境温度下的摩擦学性能。结果表明：PTFE的加入有效改善了PEEK复合材料在不同环境温度下的摩擦学性能；随着环境温度的升高，纯PEEK的摩擦系数和磨损率先减小后增大，10%PTFE/PEEK复合材料的摩擦系数和磨损率逐渐减小；当环境温度为150℃时，纯PEEK的摩擦系数最低，为0.24,磨损率为3.5×10~(-6) mm~3/(N·m);在室温条件下，10%PTFE/PEEK的摩擦系数为0.11,磨损率为3.84×10~(-6) mm~3/(N·m);当环境温度为210℃时，10%PTFE/PEEK的摩擦系数最低，为0.07,与室温相比降低了36%,磨损率为9.9×10~(-7) mm~3/(N·m);纯PEEK的磨损机制主要为黏着磨损，10%PTFE/PEEK复合材料的磨损机制以磨粒磨损和黏着磨损为主。
