A Summary of Study on Friction and Modification of PTFE CompositesKang Kejia Du Sanming Zhang Yongzhen Zhang Zhiyuan School of Materials Science and Engineering,Henan University of Science and Technology,Luoyang Henan 471003 ,ChinaAbstract:The friction process of polytetrafluoroethene （PTFE）composites was given, which was composed of three stages （ running in stage, stable stage and unstable stage）. There was strong correlation between friction coefficient and friction temperature. The failure mechanisms of PTFE composites were analyzed. The three ways of the PTFE modification were summarized, that was filler modification, in-situ composite, sintering and moulding. The research situation and the major research ideas of PTFE in recent years were summarized, and some related research ideas were put forward.[著者文摘]
