摘要
通过对CYD128型环氧树脂/新型酸酐/活性稀释剂/促进剂固化体系的相关特性进行测试分析,确定其符合真空吸注工艺要求。随后制备浇注体,并采用真空吸注成型工艺制备复合材料,测试浇注体的力学性能、热变形温度以及复合材料(纤维体积分数为52.5%)的力学性能。结果表明:该固化体系浇注体和真空吸注复合材料的综合性能优异,且工艺适用期长,适合大型制件。
The relevant characteristics of CYD128 type epoxy resin/new-type anhydride/reactive dilute/accelerant curing system were tested and analyzed. It is proved that the curing system could meet the requirements of vacuum-assisted resin infusion process. Then a casting body was prepared, and a composite was prepared by vacuum-assisted resin infusion process. The mechanical properties and heat distortion temperature of the casting body and the mechanical properties of the composite with 52.5% volume fraction of fiber were tested. The results show that the casting body and the composite have excellent overall performance and long application period, which are suitable for manufacturing of large part.
