分别制备了PTFE／碳纤维、MoS2／碳纤维混杂增强的尼龙66复合材料，用MM-2000型摩擦磨损试验机评价其摩擦磨损性能，用SEM和XPS分析了磨损表面。结果表明：PTFE／碳纤维混杂增强可以明显改善尼龙复合材料摩擦学性能；MoS2／碳纤维混杂增强没有改善复合材料的摩擦学性能；MoS2在摩擦过程中氧化生成的MoO3充当了摩擦副之间的磨粒，其磨损机理推测为粘着和磨粒磨损的综合作用。 |

Carbon fiber, PTFE and MoS2 reinforced nylon 66 （polyamide 66） composite materials were prepared and their friction and wear behaviors were evaluated using an MM-2000 friction tester. The worn surface morphology and surface element analysis were studied by scanning electron microscopy （SEM） and X-ray photoelectron spectroscopy （XPS）. The tribological properties of composites were effectively improved by adding 15% PTFE. But the friction coefficient and wear rate of MoS2 and carbon fiber hybrid reinforced composites were increased due to the tribochemical reaction between the surface of materials and formed MoO3. |
