Abstract Polytetrafluoroethylene (PTFE)/Kevlar fabric composites have been widely used for their good tribological properties in dry friction, especially in the extreme condition. In this study, the tribological properties of PTFE/Kevlar fabric composites under overloading conditions (240–330 MPa) were studied showing the friction coefficient about 0.086 and the wear rate of approximately 0.1 mm/h. A double-layer transfer membrane was formed by tribol tests. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were conducted to reveal the formation and wear mechanism of it. This new investigation of double-layer transfer membrane has significant impact with great potential in a wide range of engineering applications such as heavy loading machinery equipment and aerospace industry.

重载下 PTFE/Kevlar 织物复合材料的摩擦学性能

摘要 聚四氟乙烯（PTFE）/Kevlar 织物复合材料在干摩擦，特别是在极端条件下具有良好的摩擦学性能，被广泛应用。在本研究中，研究了 PTFE/Kevlar 织物复合材料在过载条件下 (240–330 MPa) 的摩擦学性能，摩擦系数约为 0.086，磨损率约为 0.1 mm/h。通过摩擦试验形成双层转移膜。进行扫描电子显微镜（SEM）和能量色散X射线光谱（EDS）以揭示其形成和磨损机制。这种对双层转移膜的新研究具有重大影响，在重载机械设备和航空航天工业等广泛的工程应用中具有巨大潜力。
