【摘要】 研究了树脂基摩阻材料的基体共混改性对树脂基摩阻材料/喷射沉积铝基复合材料摩擦副在干摩擦状态下摩擦磨损性能的影响,着重探讨了腰果壳油改性酚醛树脂与丁腈橡胶(NBR)的比例对摩擦副的影响,在此基础上制备出了用于1∶1台架制动试验的树脂基闸片。结果表明:对于铝基复合材料,树脂基摩阻材料腰果壳油改性酚醛树脂与丁腈橡胶的最佳比例为1∶1,同时,1∶1台架试验结果表明所制备的树脂基摩阻材料可以很好地适用于铝基复合材料制动盘,满足200 km/h高速列车的制动要求。更多还原

【Abstract】 The effects of matrix modification of resin matrix friction materials on friction and wear of friction couple,which was composed of resin matrix friction materials and aluminum matrix composites were studied under dry sliding.Emphasis was put on the ratio of cashew-modified resin to rubber(NBR).The 1∶1 sized resin-based brake pad was fabricated based on these study.The results show that the best ratio of resin to rubber is 1∶1 as for aluminum matrix composites.At the same time the results of 1∶1 sized braking test show that the resin-based friction pad can be well applied to the aluminum matrix composites rotor,which can meet the braking demand of high speed train at the speed of 200 km/h.更多还原
