以丁氰橡胶改性酚醛树脂为基体 ,以经过表面处理的玻璃纤维为增强材料 ,研制出新型无石棉摩擦材料 ,其各项性能均达到汽车制动器衬片GB576 3- 86的规定 ,可作为目前常用石棉摩擦材料的更新换代产品 .通过详细研究玻璃纤维 (简称玻纤 )的质量分数、长度及表面状态对材料摩擦磨损性能的影响 ,得出玻纤的最佳质量分数为 15%～ 2 5% ,最佳长度为 4～ 8mm .研究结果还表明 ,采用热处理、等离子体处理和偶联剂处理后的玻纤 ,可以大大降低磨损量和改善材料的摩擦磨损性能 .
To nitrile rubber modified phenolic resin as the matrix, with the surface treatment of glass fiber as a reinforcing material, developed a new non-asbestos friction material, its performance meet the automotive brake lining GB576 3-86 requirements, as the current Commonly used asbestos friction material replacement products.By studying in detail the glass fiber (glass fiber) mass fraction, length and surface condition on the friction and wear properties of the material, obtained the best glass fiber content of 15% ~ 25 %, The best length of 4 ~ 8mm.The results also show that the use of heat treatment, plasma treatment and coupling agent after treatment of glass fiber, can greatly reduce wear and improve the friction and wear properties of the material.
