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.

多层交织聚酯纤维与聚四氟乙烯颗粒增强聚酯复合材料的磨粒磨损性能

本研究旨在系统地研究多层聚酯纤维交织与聚四氟乙烯颗粒增强聚酯基体复合材料在干摩擦条件下的磨粒磨损性能。通过根据纤维编织方向应用环块测试方法，对磨料磨损性能进行了实验研究。测试材料暴露于纯水、矿物油、HNO3 和 NH3 中 1、2、3、4 周。滑动距离和测试持续时间分别确定为 2.26、4.52、6.78 和 9.04 公里，1、2、3 和 4 小时。在与纤维增强材料垂直的方向上获得最佳耐磨性。虽然 HNO3 和 NH3 环境显着降低了耐磨性，但油和纯水环境通过润滑作用提高了耐磨性。
