以碳纤维或玻璃纤维为增强纤维，二硫化钼（MoS₂）或石墨为固体润滑剂，制备了不同配方的聚四氟乙烯（PTFE）复合材料；在干摩擦和油润滑条件下对复合材料进行了摩擦磨损试验，观察了其磨损形貌，并分析了不同增强纤维和固体润滑剂对复合材料摩擦磨损性能的影响。结果表明：在干摩擦条件下，当固体润滑剂相同时，与玻璃纤维增强的相比，碳纤维增强PTFE复合材料的磨痕宽度更小、摩擦因数更大，而当增强纤维相同时，MoS₂改性PTFE复合材料的磨痕宽度比石墨改性的小，摩擦因数比石墨改性的大；在油润滑条件下，当固体润滑剂相同时，碳纤维增强PTFE复合材料的磨痕宽度比玻璃纤维增强的小，摩擦因数比玻璃纤维增强的大，当增强纤维相同时，MoS₂改性PTFE复合材料的磨痕宽度比石墨改性的略低，摩擦因数比石墨改性的大。

Polytetrafluoroethylene (PTFE) composites with different formulas were prepared with carbon fiber or glass fiber as reinforcing fibers and molybdenum disulfide (MoS₂) or graphite as solid lubricants. Friction and wear tests under dry friction and oil lubrication conditions was conducted on the composites, the wear morphology of composites was observed, and the influence of different reinforcing fibers and solid lubricants on friction and wear properties of composites was analyzed. The results show that under dry friction condition, when modified with the same solid lubricant, the carbon fiber reinforced PTFE composite had a smaller wear scar width and a larger friction coefficient than that reinforced with glass fiber; with the same reinforcing fiber, MoS₂ modified PTFE composite had a smaller scar width and a larger friction coefficient than the graphite modified PTFE composite. Under oil lubrication condition, when modified with the same solid lubricant, the wear scar width of carbon fiber reinforced PTFE composite was smaller than that of glass fiber reinforced PTFE composite, and the friction coefficient was larger; when the reinforcing fiber was the same, the wear scar width of MoS₂ modified PTFE composite was slightly smaller and the friction coefficient was larger than that of graphite modified PTFE composite.
