论述了不同含量的聚四氟乙烯对聚酰亚胺（ＰＩ）／聚四氟乙烯（ＰＴＦＥ）复合材料摩擦磨损性能的影响。研究结果表明，ＰＴＦＥ的加入可有效地改善ＰＩ的摩擦磨损特性，当ＰＴＦＥ含量在１０～２０％的范围内时，可明显降低ＰＩ的摩擦系数，其磨损特性主要表现为磨料摩擦和粘着磨损。在ＰＩ中添加不同含量的ＰＴＦＥ的比较结果为：当ＰＴＦＥ含量为２０％时，复合材料的综合性能最佳。
The effects of different contents of polytetrafluoroethylene on the friction and wear properties of polyimide (PI) / polytetrafluoroethylene (PTFE) composites were discussed. The results show that the addition of PTFE can effectively improve the friction and wear properties of PI. When the content of PTFE is in the range of 10 ~ 20%, the friction coefficient of PI can be obviously decreased. The wear characteristics of PI are mainly abrasive friction and adhesive wear. The comparison result of adding different amounts of PTFE in PI is that when the content of PTFE is 20%, the composite material has the best overall performance.
