摘　　要：采用共聚的丙烯酸甲酯-丁二烯-苯乙烯核壳结构微纳米橡胶粒子增韧氰酸酯1环氧树脂。研究结果表明,加入核壳粒子后,CEEP树脂韧性获得提高。随着核壳粒子用量从Ophr增加到30phr,室温剪切强度和90°剥离强度逐渐增加,150℃剪切强度轻微下降。热失重研究结果表明.核壳粒子加入后,树脂体系固化物起始热分解温度仅下降了5~10℃,下降幅度较小。SEM微观形貌显示,随着核壳粒子用量的增加,树脂由脆性断裂演变为韧性断裂。The cyanate ester/epoxy resin is toughened with the micro-nano rubber particles with a copolymerized methyl acrylate-butadiene-styrene core-shell structure.The results show that the toughness of CE/EP resin is greatly improved by adding core-shell rubber particle.With the in-crease of the content of core-shell particles from 0 to 30phr,the room temperature shear strength and 90 peel strength gradually increases,however the shear strength at 150℃decreases slighuly.The thermal weight loss study indicates that the initial thermal decomposition temperature of the cured resin system decreases by only 5~10℃with the addition of core-shell rubber particles.The SEM image shows that the resin changes from britle frac-ture to ductile fracture with the increase of the amount of core-shell rubber particles.
