STUDY ON FRICTIONAL AND MECHANICAL PERFORMANCE OF PTFE NANOCOMPOSITES

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.
