Abrasive wear performance of multi-layer interwoven polyester fiber & PTFE particle reinforced polyester composite

This study aims to systematically investigate the abrasive wear performance of composite material with multi-layer polyester fiber interweaving and PTFE particle reinforced polyester matrix under dry friction conditions. Abrasive wear performance experimentally investigated by applying the block on ring test method depending on the direction of fiber weaving. The test material exposed to pure water, mineral oil, HNO3, and NH3 for 1, 2, 3, 4 weeks. The sliding distances and test durations were determined to be 2.26, 4.52, 6.78 and 9.04 km, 1, 2, 3 and 4 hours respectively. The best wear resistance was obtained in the perpendicular direction to the fiber reinforcement. While HNO3 and NH3 environments significantly decrease the wear resistance, oil and pure water environments increase the wear resistance by lubricant effect.
