Modified basalt fibers reinforced rubberbased composites were prepared by hotpress molding process.The mechanical property and tribological behavior of the prepared materials were investigated,and the friction surface and abrasive dust were analyzed by Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS).The results show that compared with the composites reinforced with hydrophobic agent and silane coupling agent modified short basalt mineral fiber and silane coupling agent modified short basalt mineral fiber respectively,due to the the participation of the debris of basalt fiber,the composite reinforced with polyvinyl acetate and silane coupling agent modified basalt fiber can form a complete and stable friction film on the friction surface,which contribute to stabilize the friction coefficient and reduce the wear,and presents better tribological performance.
