Study on Tribological Properties of Carbon Fiber and Nano Boron Nitride Reinforced Polyetheretherketone/Polytetrafluoroethylene Composites
摘要
Abstract
Polyetheretherketone/polytetrafluoroethylene(PEEK/PTFE)composite spline was prepared by injection molding with carbon fiber(CF)as reinforcing phase and nano boron nitride(h-BN)with different contents.Tensile test was carried out by mechanical testing machine,surface friction test was carried out by friction testing machine,wear mark data and three-dimensional morphology were observed by a white light instrument,and wear mark was observed and analyzed by SEM.The results show that with the increase of h-BN content,the maximum spline stress of PEEK/PTFE composites first increases and then decreases;When h-BN content is 3%and 6%,the maximum stress of PEEK/PTFE composite spline is 174 MPa and 165 MPa,respectively.Compared with PEEK/PTFE,the friction coefficient of the sample with CF alone decreased to 0.23.When CF and h-BN are added at the same time,the friction coefficient of composite spline decreases.When the content of h-BN is 3%and 6%,the friction coefficients of composite splines are 0.06 and 0.09,respectively.With the increase of h-BN content,the wear of PEEK/PTFE/CF/h-BN composites first decreased and then increased.When the content of h-BN is 3%,the wear rate of composite spline is the lowest.关键词
