摘　　要：采用环-块式摩擦磨损试验机研究了玄武岩纤维增强环氧树脂基复合材料在不同载荷和速度下的磨损行为与机制.结果表明:在相同载荷200N时,速度对摩擦系数的影响不大,而磨损率随着速度的增加而增大;在相同速度0.84m/s条件下,摩擦系数和磨损率都随载荷的增加而增大.低速低载时磨损主要表现为粘着磨损;高速低载时有玄武岩纤维从基体中脱落,表现为磨粒磨损特征;高速高载时磨损机理为基体疲劳剥落和磨粒磨损.The wear properties of basalt fiber reinforced epoxy resin matrix composite under different load and speed are investigated by using a block-on-ring tribometer. The results show that under the same load of 200 N, the friction coefficient is hardly changed, while the wear rate increases with the increase of the speed. Both the friction coefficient and the wear rate increase with the increase of the load under the same speed of 0.84 m/s. Under the low load and speed the main mechanism governing the wear properties of composite is adhesive wear; the wear loss is controlled by abrasive wear due to the pull-out of basalt fiber under high speed and low load ; and the wear mechanism changes into fatigue scale of matrix and adhesive wear under high load and speed.
