本文研究了碳纤维聚苯硫醚复合材料在无润滑和与钢滑动摩擦条件下,摩擦力,磨损率,表面接触温度,接触电阻等随负荷及纤维含量的关系。结果表明,摩擦力、接触温度,磨损率均随负荷增大而增大。随着纤维含量的增加,摩擦力与接触温度有一个最小值,而磨损率则先呈现一个最小值而后出现一个最大值。随着纤维含量的增加,主要的磨损机理可能从粘附磨损过渡到疲劳磨损。对磨面的形貌与化学状况对摩擦与磨损有明显的影响。
In this paper, the relationship between friction, wear rate, surface contact temperature, contact resistance, etc. with load and fiber content of carbon fiber polyphenylene sulfide composites under non-lubricated and steel sliding friction conditions was studied. The results show that friction, contact temperature and wear rate increase with the increase of load. As the fiber content increases, the friction and contact temperature have a minimum, while the wear rate first presents a minimum and then a maximum. As the fiber content increases, the primary wear mechanism may shift from adherent wear to fatigue wear. The morphology and chemical state of the abrasive surface have a significant effect on friction and wear.
