【摘要】 环氧树脂是一种综合性能优良的热固性树脂,但其韧性不足。从增韧机理出发,对增韧环氧树脂的主要方法进行了探讨,包括橡胶弹性体、无机刚性粒子、核壳粒子、热致液晶聚合物(TLCP)、互穿聚合物网络(IPN)、热塑性树脂增韧环氧树脂。在比较的基础上,对环氧树脂的增韧进行展望,指出其今后发展的方向。更多还原

【Abstract】 Epoxy resin is a kind of thermosetting resin with excellent general performances,but its toughness is not enough. Several main toughening methods for epoxy resin are discussed and compared from mechanisms . These methods are elastomeric rubbers,inorganic and rigid particles,core-shell particles, thermotropic liquid crystal polymer (TLCP) and interpenetrating polymer network (IPN) and thermoplastic resin. On the basis of compare, expectation and development are made on toughening of epoxy resin.更多还原
