Compared to traditional fiberglass, basalt fibers have a wide spectrum of applications used as textile fiber or reinforcement for composites. Epoxy resin composites filled with basalt fibers were prepared by proper curing, using KH-550 silane coupling agent to enhance the interfacial bonding between the inorganic reinforcing agent and the polymer matrix. The milling abrasive wear was investigated in slurry containing sand abrasive particles using milling equipment. The experimental results indicated that basalt fibers, EP and the nano-sized SiO2 filling formed steady composites. The wear rate of the sample was reduced with the increase of resin content before the content of resin amounted to 40%. When the content of resin is more than 40%, the wear rate of the sample deceased slightly.
