Epoxy resin glass mat laminated sheets were prepared by the epoxy resin modified by heat resistant modifier and three different types of chopped glass mat, and their mechanical properties and electrical properties were tested. The results indicate that the heat resistance of the epoxy resin glass mat laminated sheet prepared by the modified epoxy resin is improved obviously. The comprehensive proper-ties of the modified epoxy resin glass mat laminated sheet prepared by type A glass mat are better, and the heat resistance attain grade H, which can satisfy the IEC standard requirements of EPGM305 and can reach the technical level of foreign similar products.
