The friction and wear properties of polytetrafluoroethylene/Kevlar (PTFE/Kevlar) fabric under different loading conditions were investigated by using MXW-05 rotating friction and wear tester.A stereo microscope,a three-dimensional optical profiler,a field emission scanning electron microscope,and an energy dispersive spectrometer were used to conduct macro- and micro-analysis on the fabric's wear scar.The results indicated that the friction coefficient of the PTFE/Kevlar decreased firstly and then increased with the increase of load.The friction coefficient of PTFE/Kevlar was the lowest when the load was 2N,and the highest when the load was 10N.With the increase of load,the friction behavior between the fabric material and GCr15 bearing steel was characterized by the continuous generation,peeling and regeneration of PTFE transfer film,but the damage characteristics were not completely the same.The wear mechanism of fabric consisted of fatigue wear,abrasive wear and some oxidation wear.
