Outline
In this paper, epoxy resin bulk molding compound (EP-BMC) was prepared by mixing short cut glass fibers and calcium sulfate whiskers with epoxy resin matrix. After molding and curing, the influence of glass fiber filler ratio on the wear resistance, mechanical properties, and dimensional stability of EP-BMC material was researched. The results show that with the increase of glass fiber filler ratio, the wear resistance and the linear expansion coefficient of EP-BMC material after thermal ageing decrease continuously, while the tensile strength and bending strength increase at first and then decrease. When the mass ratio of glass fiber to filler is 30∶40, the EP-BMC material shows optimal comprehensive performance. After thermal ageing, the volume wear is 1.00 mm3, the tensile strength and bending strength is 56 MPa and 145 MPa, respectively, the linear expansion coefficient is 24.94 μm·m-1·℃-1, and the volume resistance reaches 2.0×1013 Ω.
