| Abstract: | Epoxy resins are wildly used as high performance thermosetting resins due to their unique characteristics of high strength,stiffness,hardness and excellent chemical and heat resistance.However,such epoxy systems show inherent brittleness and poor resistance to crack initiation and growth.In order to solve this problem,impact modifiers were added into epoxy resins in order to improve toughness.The toughening modification methods for epoxy resins and their mechanism were reviewed,such as liquid rubbers,thermo... |
