硅灰棉是树脂基摩擦材料常用的主要组分之一，分别采用硅烷偶联剂CX-602与KH-550，以及钛酸酯偶联剂TCA-201与TCA-311w对硅灰棉进行表面改性，以期改善材料的摩擦磨损性能。利用D-MS150定速实验机和ZYMM-1000缩比台架试验机(1：6)对摩擦材料试样进行摩擦磨损性能测试，研究偶联剂改性硅灰棉对树脂基摩擦材料结构与摩擦学性能的影响。结果表明，用KH-550表面改性硅灰棉制备的树脂基摩擦材料的摩擦磨损性能最佳，高温摩擦因数比未改性的试样提高22%，并且摩擦因数的稳定性最好，热衰退率最低(14%)，摩擦试验后的质量损失和厚度损失都最小，分别为1.38 g和1.04 mm。

As one of the main components, silica fume cotton is used commonly. In order to improve the friction and wear performance of resin-based friction material, the surface of silica fume cotton was modified using silane coupling agent (CX-602 and KH-550) and titanate coupling agent (TCA-201and TCA-311w). The effect of coupling modified silica fume cotton on the tribology capability of resin-based friction materials was studied. D-MS150 constant speed friction testing machine and MM-1000 bench testing machine (1:6) were used to study the frictional wear performance. The microstructure of the frictional samples was characterized by SEM. The results show that, resin-based friction material modified by KH-550 surface-modified silica fume cotton has the best friction and wear performance. The high temperature friction coefficient of the material increases by 22%. The thermal recessional rate is 14%. The mass loss is 1.38 g and thickness loss is 1.04 mm, which are the lowest in all of the samples.
