摘要
将各种填料加入树脂中,制备环氧树脂和聚氨酯复合材料,将树脂复合材料与聚酯纤维织物复合制备环氧/聚酯纤维织物、聚氨酯/聚酯纤维织物复合材料,采用Amsler摩擦磨损试验机考察复合材料的摩擦磨损性能,采用SEM分析磨损表面形貌,并分析其摩擦机制。结果表明:聚四氟乙烯改善环氧/聚酯纤维织物复合材料摩擦磨损性能,降低其摩擦系数,减小磨损量;MoS_2改善PU/PET复合材料摩擦磨损性能,降低复合材料的摩擦系数,减小磨损量;摩擦试验时方向对聚酯纤维复合材料的干摩擦磨损性能有一定影响,对于粘合性能好的环氧/聚酯纤维织物复合材料,偏轴方向(30°、45°和60°)上具有较低的摩擦系数和磨损率;摩擦试验时方向对酚醛聚酯纤维织物和酚醛棉纤维织物复合材料干摩擦磨损性能也有一定影响,摩擦性能与纤维性能、基体树脂性能及二者粘接性能等因素密切相关。
Epoxy composites and polyurethane composites were prepared by adding difffent fillers.EP/PET and PU/PET fabric composites were prepared by resin composites combined with polyester fabric.The friction wear properties of composites were investigated on the Amsler friction-wear tester,the morphology of worn surface were analyzed by SEM.The results showed that the polyester fabric composites with PTFE MoS_2 had good anti-wear and friction-reducing behavior,the sliding direction of tribo-pair had a definite influence on the friction wear properties of composites.The friction wear properties of composites on the off axis（30°,45°and 60°）were influenced by the adhesive performance of fabric and resin matrix.
