摘　　要：以聚丙二醇二缩水甘油醚(PPGDGE)为增韧剂改性环氧树脂E-51/甲基四氢邻苯二甲酸酐固化体系,通过力学性能、耐热性和形状记忆性能测试等研究了PPGDGE用量对该环氧体系性能的影响。结果表明:PPG-DGE添加质量分数为10%时,体系最大形变量增加约43%,形状回复速率增长75%;添加15%PPGDGE时,体系固定率提高了2.2%,回复率提高了4.5%,同时冲击强度提高了65%。PPGDGE的加入使得环氧树脂形状记忆性能有了大幅度提高。The effects of polypropylene glycol diglycidyl ether（PPGDGE） content on the properties of modified epoxy resin E-51 / methyl tetrahydro phthalic anhydride curing system using PPGDGE as toughening agent were investigated by the testings of mechanical properties,heat resistance and shape memory performance.The results showed that： the maximum deformation and shape recovery rate of the system with PPGDGE mass fraction 10% were increased by approximately 43% and 75%,respectively.The fixed rate,recovery rate and impact strength of the system with 15% PPGDGE were increased by 2.2%,4.5% and 65%,respectively.The shape memory performance of the epoxy resin was greatly improved by adding PPGDGE.
