Investigation of the transfer film characteristics and tribochemical changes of Kevlar fiber reinforced polyphenylene sulfide composites in sliding against a tool steel counterface

摘要

Composites of polyphenylene sulfide reinforced with Kevlar 29 fiber were prepared by compression molding. The friction and wear behavior of the composites was examined with a pin-on-disc test rig. The morphologies and elemental composition of the transfer films on the counterface were analyzed with a scanning electron microscope equipped with an energy dispersive spectrometer. The tribochemical changes of polyphenylene sulfide composites during friction were examined by means of X-ray photoelectron spectroscopy.
