摘　　要：本文采用腰果壳油、三聚氰胺改性粉末酚醛树脂为基体,陶瓷纤维、钛酸钾晶须和kevlar纤维混杂制备制动摩擦材料,研究了不同混杂纤维含量对摩擦材料摩擦磨损性能影响。结果表明,增强纤维含量过低或者过高均会导致摩擦材料摩擦性能的降低。陶瓷纤维、钛酸钾晶须和kevlar三种增强纤维混杂使用能够提高并稳定制动摩擦材料的摩擦系数,对降低摩擦材料的磨损率有明显的作用。推荐在纤维混杂摩擦材料配方中采用25%的纤维含量和3%的Kevlar纤维含量。The investigation was concentrated on brake friction materials, which were prepared busing CNSL and melamine modified powder phenolic formaldehyde resin as bonding materials, ceramic fibre, PTW（ potassium titanate whiskers） and kevlar as reinforce materials in this paper. The effects of fibre content on the friction and wear property of brake friction materials were stu- ied. It was demonstrated from the results of experimentation that the performance of friction material will be reduced when the fiber content is too low or too high, and the ceramic fibre, PTW and kevlar brake friction material have extremely stable higher friction coefl＇icientand lower wear rate. By adopting 25 % fibers composite content, 3 % Kevlar content, the friction materials has good friction and wear property.
