环氧树脂增韧改性及其作用机制研究进展
Research progress on toughening modification of epoxy resin and their mechanism
摘要
Abstract
Epoxy resin,as one of the most strategically significant thermosetting polymer materials,is widely used in national defense equipment and economic fields,due to its unique chemical structure and ex-cellent performance.However,epoxy resins,known for their high cross-linking density,often suffer from issues such as insufficient toughness,susceptibility to microcracks and other defects.These limitations re-strict their wide application in advanced manufacturing.Focusing on the effective toughening methods for epoxy resin and its composite materials,this work reviews the toughening effects of intrinsic self-toughe-ning methods and extrinsic reinforcement toughening methods on epoxy resin and its composite materials.Furthermore,it focuses on the toughening mechanism and effects of core-shell nanoparticles.Additional-ly,we note that the varying toughening effects stem from the synergistic effects of different toughening mechanisms.The purpose of our review is to foster wider and more in-depth applications of epoxy resin-based composite materials,while offering insights for the development of such materials that possess both superior toughness and strength.关键词
