目的 研究MoS2和石墨填充对自润滑纤维织物复合材料摩擦学性能的影响。方法 采用玄武三号栓-盘式摩擦磨损实验机，研究了石墨和MoS2填充PTFE/棉纤纤维织物在不同载荷条件下的摩擦磨损性能，并采用扫描电镜观察了纤维织物复合材料的磨损表面和微观结构。结果 在较低载荷下，填充5% MoS2可以更有效地降低PTFE/棉纤纤维织物复合材料的磨损率；在较高载荷下，填充10%石墨可以更有效地降低PTFE/棉纤纤维织物复合材料的磨损率。载荷为219.52 N时，5% MoS2填充PTFE/棉纤纤维织物复合材料的磨损率由未填充的1.28×10-14 m3/(N?m)降低到0.61×10-14 m3/(N?m)，降低了50%；10%石墨填充PTFE/棉纤纤维织物复合材料的磨损率由1.28×10-14 m3/(N?m)降低到0.91×10-14 m3/(N?m)，降低了28%。结论 石墨和MoS2填充在摩擦过程中减轻了磨粒的嵌入和切削作用，阻碍了复合材料的磨损，提高了PTFE/棉纤纤维织物复合材料的耐磨性能。

The work aims to study effects of MoS2 and graphite filling on tribological properties on self-lubricating fabric composites. Friction and wear properties of MoS2 and graphite-filled PTFE/cotton fabric were studied under various loading conditions, and worn surface and microstructure of the fabric composites were observed with scanning electron microscopy (SEM). Under lower loads, filling with 5% MoS2 could reduce wear rate of PTFE/cotton fabric composites more effectively; whereas under higher loads, filling with 10% graphite could reduce wear rate of the composites more effectively. Provided with wear rate of 219.52 N, wear rate of the PTFE/cotton fabric composites filled with 5% MoS2 decreased from 1.28×10-14 m3/(N?m) to 0.6×10-14 m3/(N?m) by 50%; wear rate of the composites filled with 10% graphite decreased from 1.28×10-14 m3/(N?m) to 0.91×10-14 m3/(N?m) by 28%. Filling with graphite and MoS2 alleviates embedding and cutting effects of abrasive grains, inhibits wear of the composites and improves wear resistance of PTFE/cotton fabric composites.
