PREDICTION OF DEPENDENCE OF WEAR OF CARBOPLASTICS ON PRESSURE AND SLIDING VELOCITY

摘要

A method is proposed on how to predict the linear wear rate of carboplastics as a function of test conditions (pressure and sliding velocity). The method is based on using the structural characteristics and it yields a good correlation with the experiment. Introduction. Composites reinforced with carbon fibers are promising materials used in friction units. The carboplastics are used with success to replace traditional structural antifriction materials. Yet the lack of a quantitative structural model of the polymer matrix had until recently been a serious obstacle to the analytical description of friction and wear of carboplastics. The authors studied how the wear of carboplastics based on phenylon depends on pressure and sliding velocity within the framework of the cluster model of polymers and fractal analysis that enabled to reveal the governing role of polymer matrix structure in friction and wear.
