摘　　要：为了充分利用废物研发绿色制动材料,以树脂为基体,不同掺量煤矸石粉作为无机填料,竹纤维作为增强相,添加镁盐晶须、硫酸钙晶须、铜粉和石墨,用热压成型的方法制备试样,测试试样的力学性能和摩擦学性能。结果表明,随着掺量的增加,洛氏硬度增大,而冲击强度略有下降。摩擦系数随掺量的增加而增大,高温阶段煤矸石粉可以改善热衰退性,稳定摩擦系数,有良好的耐热性和热稳定性。煤矸石粉可以促进摩擦层的形成,掺量为20%的试样具有较好的综合性能。In order to make full use of waste materials, different coal gangue powder is added to resin-base as inorganic fillers to re- search on green brake pads, together with bamboo fiber, magnesium whisker, calcium sulfate whisker, copper and graphite. Hot pressing is used in specimen preparation and its mechanical properties tribological performances are tested in the experiment. The results show that its hardness increases with the dosage increasement of coal gangue fines, while its impact strength is decreased slightly. As the amount of coal gangue fines increases, its friction coefficient increases accordingly. In the phase of high temperature, coal gangue could improve the heat recession as well as the stabilize friction coefficients. In conclusion, the specimen, added coal gangue to, has good heat-durability and thermal stability. Coal gangue powder can promote the formation of the friction layer, and it is known in the experiment that specimen with 20% dosage has good synthetic properties.
