众所周知,纤维增强复合材料已经获得了广泛的应用,它们在滑动部件中的应用也日益增多。材料的摩擦系数和耐磨损性在很大程度上取决于纤维的方向。美国麻省理工学院两位研究人员就单轴向的石墨纤维/环氧树脂和双轴向的玻璃纤维/二硫化钼/聚四氟乙烯复合材料的摩擦系数和磨损速率作了研究。据研究者报告,纤维排列方向分A向和B向两种。A向表示纤维方向与滑动表面垂直,B向表示纤维与滑动方向横切。当石墨纤维/环氧试样(纤维占体积60％)的滑动方向与B
As we all know, fiber-reinforced composites have been widely used, and their applications in sliding parts are also increasing. The coefficient of friction and abrasion resistance of the material depend very much on the orientation of the fibers. Two researchers at the Massachusetts Institute of Technology studied the friction coefficient and wear rate of uniaxial graphite / epoxy and biaxial glass / molybdenum disulfide / polytetrafluoroethylene composites. According to the researchers’ report, fiber orientation is divided into A direction and B direction. A indicates that the fiber is perpendicular to the sliding surface, and B indicates that the fiber is transverse to the sliding direction. When the graphite fiber / epoxy specimen (fiber volume accounted for 60%) of the sliding direction and B
