PTFE编织复合材料摩擦特性研究
Study on Friction Characteristics of PTFE Braided Composites
摘要
Abstract
The dry friction tests of PTFE braided composites were carried out on high-speed tribo-test-er with speed, load as variables. The influence of different speed, load on the friction coefficient were analyzed. The results show that friction coefficient is stable reducing trend and finally stabilized with increasing load. Friction coefficient with the speed of change trend is: between 10-20kN, with increasing of the frequency, friction coefficient gets a minimum value and then rises to a steady value. The influence of the load on the friction coefficient is greater than that of frequency on the friction coefficient. Through the analysis of the microstructure of the liner using scanning electron microscope, the influences mechanism of speed, load on the friction coefficient was explained.关键词
