中文摘要：

采用芳砜纶、玄武岩和硅灰石为纤维增强体，锆英石为磨料，石墨为固体润滑剂，蛭石和重晶石分别为降低噪音和成本的填料，腰果酚型苯并曙嗪改性的酚醛树脂为基体，制备了含芳砜纶的制动摩擦材料。测定了摩擦材料的热衰退性、热恢复性和体积磨损率。结果表明，芳砜纶具有降低摩擦系数和改善体积磨损率的作用，含9％体积分数芳砜纶的制动摩擦材料具有最佳摩擦性能。

英文摘要：

Non-metallic brake friction materials containing polysulfonamide fibers （PSA）, basalt fibers, and wollastonite as reinforcements, zircon as abrasive, graphite as solid lubricant, vermiculite as noise-reducing filler, barite as cost-reducing filler, and cardanol-based benzoxazine modified phenolic resin as binder have been formulated and their composites were prepared. The presence of PSA was found to depress the friction coefficient and improve the wear rate of the friction composites. The optimal friction performance was obtained with a volume fraction of 9 % of PSA.
