【Abstract】 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.更多还原
