为提高树脂基摩擦材料摩擦因数稳定性,改善其抗热衰退性能.以碳纤维作为增强纤维,采用热压成型工艺制备碳纤维增强树脂基摩擦材料;用XD-MSM型定速摩擦试验机测定摩擦磨损性能,研究了不同含量碳纤维增强对树脂基摩擦材料摩擦磨损性能的影响;利用VK-X200三维激光扫描显微镜观察了摩擦材料磨损后表面的微观形貌并探讨其磨损机理.结果表明,碳纤维增强树脂基摩擦材料的硬度、压缩强度和剪切强度均得到提高,并随碳纤维含量的增加而逐渐增大;碳纤维增强作用提高了树脂基摩擦材料的耐磨性和摩擦因数的稳定性,改变了树脂基摩擦材料的摩擦磨损形式;碳纤维含量为4wt％的增强树脂基摩擦材料摩擦因数稳定性较高,抗热衰退性能较好,磨损机制主要为疲劳磨损.
