The Effects of Environmental Temperature and Humidity on the Friction and Wear Performance of PTFE Braided Composites

Abstract:

With the rapid development of advanced science and technology, the performance requirements of the PTFE fabric composite is rapidly increase. In this work, the dry friction tests of PTFE braided composites were carried out on high-speed Tribo-tester analysing the influence of different working conditions to the friction temperature and humidity in the measurement of friction characteristics experiments. Scanning electron microscopy (SEM) was utilized to examine composite microstructures and study modes of failure. Energy spectrometer analysis was also performed to study the wear surface and the ingredient of the debris in an effort to get the mechanism of the composites damage.
