An epoxy resin-based sheet molding plastic (E-SMC) was prepared by using multi-function epoxy resin as the resin matrix, dicyandiamide as main curing agent, and mica as fillers. Then the epoxy molding composite was prepared by molding process, and its mechanical properties, thermodynamic properties, and electrical properties were systematically tested and studied. The results show that the epoxy molding composites have high mechanical strength, and the tensile strength, bending strength, vertical compression strength and parallel compression strength of typical samples can reach 64, 178, 440, and 332 MPa, respectively. At the same time, the epoxy molding composites have low density (1.69-1.76 g/cm3), high glass transition temperature (Tg up to 201℃), and excellent electrical strength properties, and the breakdown voltage of typical samples is up to 100 kV, the electric strength can reach 17.1 kV/mm, the comparative tracking index (CTI) is 600 V.
