摘要:

采用湿法工艺制备出一种碳纤维增强纸基摩擦材料,通过惯量试验机研究了长时间连续制动条件下碳纤维增强纸基摩擦材料的摩擦磨损性能变化规律.利用扫描电子显微镜和三维轮廓仪观察磨损表面形貌并分析其磨损机理.结果表明:随着制动次数的增加,摩擦力矩曲线波动现象严重,摩擦系数减小,摩擦表面由于形成了光滑的摩擦膜使磨损率大幅度降低.

Abstract:

Carbon fiber reinforced paperbased friction material was prepared by paper-making process. The friction and wear performance of samples under repeated braking condition were investigated by a QM1000-Ⅱ wet friction performance tester.The scanning electron microscope and 3D non-contact surface profiler were employed to analyze the worn surface and understand wear mechanisms. Experimental results indicated that the friction torque curve became fluctuating and friction coefficient decreased with the increase of braking cycles, while wear resistance of the samples increased due to continuous friction film formed on the worn surface during the friction process.

Key words: paper-based friction material, carbon fiber reinforced, repeated braking, friction and wear performance
