The present invention discloses high-strength and high-toughness epoxy resin. The high-strength and high-toughness epoxy resin is obtained by curing of the following raw materials: 38wt%-59wt% of substrate resin, 38wt%-59wt% of a curing agent and 0.1wt%-3wt% of an accelerator; the substrate resin is a mixture of epoxy resin and a reactive diluent; the reactive diluent is a weakly-polar epoxy compound with side chains. The epoxy resin cured material with high tensile strength, high tensile modulus and good toughness is obtained by adding a proper amount of weakly-polar and low-viscosity epoxy resin to obtain a low-viscosity epoxy resin component, mixing the obtained epoxy resin component, the curing agent and the accelerator, and performing a curing reaction. According to the invention, various epoxy resin is suitable for preparing the epoxy resin cured material provided by the invention, and the method is simple. 本发明公开了种高强度高韧性环氧树脂。所述高强度高韧性环氧树脂是由包括以下组分的原料固化而得：基体树脂、固化剂、促进剂；所述的各组分按重量百分比计：基体树脂为38wt％-59wt％；固化剂为38w
