摘　　要：研究了丁腈羟增韧环氧树脂的力学性能和形态结构．丁腈羟的用量、丁腈羟中丙烯腈的含量、固化条件对所形成的微区尺寸都有较大影响，并进一步影响固化物的力学性能．The morphologies and mechanical properties of epoxy resins toughened by hy-droxyl-terminated butadiene-acrylonitrile copolymer (HTBN ) and cured with hexahydroph-thalic anhydride were studled. The results show that the level of HTBN in epoxy resin, con-tent of acrylonitri1e in HTBN and curing temperature influence the morphology and then in-fluence the mechanical properties of cured epoxy resin.
