采用粘度、凝胶时间及力学性能测试以及示差扫描量热分析和扫描电镜研究了上纬环氧树脂2511-A体系的工艺性能,固化反应行为及其采用西曼树脂浸渍膜塑成型工艺(Seeman Composites Infusion Molding Process,SCRIMP)制成的环氧玻璃纤维复合材料的性能。结果表明:2511-A体系在25～35℃下粘度保持在600 mPa.s以下的时间长达120 min,满足SRCIMP成型工艺要求,其玻璃化转变温度为112℃。复合材料的孔隙率仅为0.19%,且具有良好的力学性能。 The viscosity, gel time and mechanical properties, as well as differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) were used to investigate the performance, the curing reaction behavior and the Seeman Composites Infusion Molding Process, SCRIMP) made of epoxy glass fiber composite performance. The results showed that the viscosity of 2511-A was kept below 600 mPa.s at 25 ~ 35 ℃ for 120 min, which satisfied the requirements of SRCIMP molding process and its glass transition temperature was 112 ℃. The porosity of the composite is only 0.19%, and has good mechanical properties.
