摘要
Abstract
ln order to make ful use of waste materials, different coal gangue powder is added to resin-base as inorganic fil ers 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. ln the phase of high temperature, coal gangue could improve the heat recession as wel as the stabilize friction coefficients. ln 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.关键词
