Progess in Study on Toughening Modification of Epoxy Resin

Thoughening methods for epoxy resin are summarized in this paper with emphasis on the mechanism and modification methods including by rubbers,thermoplastics,inorganic nano-particles,interpenetrating polymer network(IPN),thermotropic liquid crystal polymer(TLCP) and core shell polymer(CSP).Besides,the existing problems in epoxy resin toughening are generalized and the development trend in toughening mocification of epoxy resin is predicted.
