摘　　要：环氧树脂具有优良的力学性能、加工工艺性能,作为纤维复合材料的基体树脂广泛用于飞行器、风机叶片、运动器械等结构材料的制造,但是环氧树脂固化后交联密度高,因此其固化物存在韧性低、耐疲劳和耐冲击性能差的缺点,在一定程度上限制了环氧树脂的应用。对环氧树脂进行增韧一直是环氧树脂研究领域的热点也是难点问题之一。本研究介绍了几种增韧改性环氧树脂的方法,包括橡胶弹性体增韧、热塑性树脂增韧、无机刚性粒子增韧、超支化聚合物增韧、互穿聚合物网络增韧和化学改性增韧等,分析了其机理,综述了上述改性方法在国内外的研究进展。As a matrix resin of the fiber composite materials, epoxy resin is widely used in the manufacture of the structural materials of the aircraft, the fan blades, sports equipment, etc. because of the excellent mechanical properties and processing performance. However, the crosslink density of epoxy resin is high after curing, and therefore the shortcomings of low toughness, poor fatigue resistance and bad impact properties of the cured resin make the application of epoxy resin be limited to some extent. Toughening epoxy resin has been a hot research spot, also one of the difficulties. In this paper, the toughe- ning modification methods of epoxy resins by using Rubber elastomer, thermoplastic resins, inorganic particle, hyper- branched polymers （HBP）, interpenetrating polymer networks （IPN） were introduced. The toughening mechanism of each method was analyzed. The research progress of the modification methods for epoxy resin at home and abroad were reviewed.
