摘要: 论述了不同含量的聚四氟乙烯对聚酰亚胺(P I)/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P I 的摩擦磨损特性, 当PTFE 含量在10～20% 的范围内时, 可明显降低P I 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P I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。

Abstract: The effect of PTFE with different content on the property of composite material PI/PTFE is discussed in this paper. The results show that the addition of PTFE can improve the friction and wear property of PI effectively; when the content of PTFE is about 10～20%, the friction coefficient of PI decreases apparently. Co wear property mainly includes abrasive wear and adhesive wear. The results show that when the content of PTFE is 20%, the comprehensive property of composite material is the best.-
