【摘要】：针对石棉摩擦材料的分解产物致癌且严重污染环境的问题,以力学性能优异的玻璃纤维织物为基体,以酚醛-缩醛黏合剂为固化剂,制成新型无石棉复合摩擦材料。研究了固化温度和固化时间、玻璃纤维织物的纤维方向以及酚醛-缩醛黏合剂对该材料摩擦性能的影响。结果表明:当固化温度为180℃,固化时间为1 h时,该复合材料表现出优异的摩擦磨损性能,摩擦因数为0.25,且磨损最小;复合摩擦材料中垂直于纤维方向的磨损量比平行于纤维方向的少;该玻璃纤维复合材料摩擦磨损性能符合使用要求,又因其成本较低、耐热性好、机械强度良好等优点,可被广泛应用于各个领域。
[Abstract]:In order to solve the problem that the decomposition products of asbestos friction materials are carcinogenic and seriously pollute the environment, a new type of non-asbestos composite friction material is prepared by using glass fiber fabric with excellent mechanical properties as matrix and phenolic acetal adhesive as curing agent. The effects of curing temperature and curing time, fiber direction of glass fiber fabric and phenolic acetal adhesive on the friction properties of the material were studied. The results show that when the curing temperature is 180 鈩，
