PTFE复合材料力学与摩擦性能的研究

STUDY ON FRICTIONAL AND MECHANICAL PERFORMANCE OF PTFE NANOCOMPOSITES

论述了不同混合工艺、不同填充组分对聚四氟乙烯 (PTFE)力学性能、摩擦磨损性能的影响。结果表明 ,不同的混合方式对 PTPE复合材料的综合性能有较大的影响 ,碳纤维组分的加入量以及碳纤维长度的改变对PTPE的性能也有较为明显的作用。其中 ,长度为 0 .1nm的碳纤维加入到 PTFE中后 ,对 PTFE耐磨耗性能的提高较为显著。

The effects of the different mixing techniques and filling components on the mechanical and frictional performance of PTFE composites are discussed in this paper. The results show that the comprehensive property of PTFE composite is considerable influenced by the different mixing methods, and that the changes of the amount and length of carbon fibers have obvious effects on the property of PTEF. Among them, when carbon fibers with length of 0.1mm are added to PTEF composites, it can obviously improve resistance to abrasion of PTEF.
