采用造纸工艺制备了一种湿式纸基摩擦材料，研究了硫化温度对材料耐热性、动摩擦因数、摩擦力矩、磨损率、磨损表面微观形貌的影响。研究结果表明：硫化温度高于或低于160℃时，材料的耐热性能减弱，树脂和竹纤维的热分解较为严重，热磨损主要影响着材料摩擦磨损性能的稳定；160℃时，材料的磨损较小，磨损表面平整致密，在循环制动中动摩擦系数波动性较小，摩擦力矩的变化较平稳，降低了制动的噪音。

Wet paper-based friction material was prepared through the paper-making process , and the influences of curing temperature on the friction materials ,including heat resistance , dynamic friction coefficient ,friction torque ,wear rate and micro morphology of the worn sur-face were studied .The results show that the heat resistance of friction material were weak-en ,and thermal decomposition of resin and bamboo fiber became serious w hen the curing temperature is higher or lower than 160 ℃ ;the thermal worn mainly affect the stability of tribological performance of friction material .At the curing temperature of 160 ℃ ,the worn rate of friction material with flat and compact worn surface is minimum ,and dynamic friction coefficient and friction torque keep relatively stable ,which reduce brake noise .
