摘　　要：:E5 1 T31体系固化反应快 ,但粘结性能低。加入柔性环氧树脂QS 310N后固化反应速度有所降低 ,粘结性能亦有提高。在此基础上加入QS型增韧剂 ,形成具有“海岛结构”的环氧树脂合金 ,粘结性能进一步提高。The curing rate of E51/T31 system was rapid yet its adhesion was low.Addition of flexible epoxy resin QS-310N reduced the curing rate and adhesion could also be improved.Based on this,QS toughener was added to form epoxy resin alloy of“sea island structure”,thus further improving its adhesion. In the E51/T31 system,QS toughener exhibited much better toughening effect than CTBN.
