In this paper, the main defects of poor toughness and brittleness of epoxy resin and toughening modification of epoxy resin are introduced. In recent years, the main ways of toughening and modifying epoxy resin are summarized. In recent years, the use of rubber elastomer, thermoplastic resin, liquid crystal polymer, inorganic nanofiller, Materials, flexible curing agents and interpenetrating networks to toughen the epoxy resin. The problems existing in various toughening modification technologies are analyzed. The latest research progress of toughening epoxy resin is pointed out. In the future The development trend of the outlook.
