【摘要】 本文利用自制高速摩擦试验机对PTFE编织复合材料进行干摩擦试验,研究不同条件下(载荷、速度、湿度等)对PTFE编织复合材料摩擦磨损性能的影响;利用扫描电子显微镜(SEM)对不同条件下的磨屑形貌进行分析。研究结果表明:摩擦系数随载荷和相对湿度的增大而减小,随摩擦速度的增大而增大;磨损量随载荷和速度的增大而增大,随相对湿度的增大先减小后增大;载荷及速度的增加显著影响材料磨损状况。更多还原

【Abstract】 In this paper,in order to study the effect of external factors(load,speed,humidity)on the friction and wear properties of PTFE braided composites,the dry friction test of PTFE braided composites was carried out on high-speed tribo test machine;the morphology and composition of abrasive dust under different test conditions were characterized by means of scanning electron microscopy(SEM).The results show that:the friction coefficient decreases with the increasing of load or relative humidity,while shows a increasing rate with increases in speed;wear mass loss increasing with the increases in load or speed,but with the increases of relative humidity,the wear loss first decreased and then increased;The increasing of Load and speed influence material wear conditions seriously.更多还原
