A new high toughness and elevated-temperature epoxy resin system ACTECH 1316 was designed. After analyzing its curing reaction characteristic, rheological property and heat-resistant quality, the resutts showed glass transition temperature was 222.5℃ and was able to be used at the temperature of 130℃ chronically. Two kinds of domestic fiber reinforcement, such as CCF800H and ZT9H, were selected to prepare prepreg respectively by using hot melt two-step process which had excellent manufacturing process, showed good compatibility with two carbon fiber systems. Autoclave process was used to solidify prepreg, and the mechanical properties of composite laminated plates were studied, which showed better properties. Compared with the performance of high-temperature epoxy resin 8552/IM7 prepreg from abroad, 0°tensile strength and modulus, 0°compression strength and modulus and the compression strength after impact of ACTECH 1316/ZT9H and ACTECH 1316/CCF800H could meet the basic requirement for resin and composite materials in civil aviation field.
