摘　　要：采用脱水蓖麻油制聚酰胺,将之应用于环氧树脂固化体系中,并进行了DSC测试、耐热性测试和力学性能测试,综合考察了该聚酰胺与环氧树脂固化体系(DCOPA/EP)的适宜配比。研究结果表明:当DCOPA/EP固化体系以质量比0.8∶1.0混合时,固化反应最完全,固化物的耐热性能最高,冲击、弯曲及剪切性能最强。The polyamide hardener was prepared by dehydrated castor oil. Differential scanning calorimetry （ DSC ）, heat resistance tests and mechanical property tests were used to determine the fitful weight ratio of this kind of polyamide and epoxy resin （DCOPA/EP） curing system. Analysis of the results indicated when the weight ratio of the DCOPA/EP curing system was 0. 8： 1.0,the curing reaction was completed ultimately, the heat resistance of the system were highest and the resistant abilities of the impact, bending and shearing were strongest.
