研究了真空辅助树脂注射(VARI)工艺中定型剂对环氧树脂的影响及其在织物表面的分布形式,以及定型剂用量对单轴向经编织物复合材料力学性能的影响,以确定最优的定型参数.采用示差扫描量热法(DSC)和扫描电镜(SEM)分别对加入不同用量定型剂的环氧树脂的玻璃化转变温度和相形貌进行分析,并测试了加入不同用量定型剂后复合材料的力学性能.结果表明:随着定型剂用量的增加,环氧树脂的玻璃化转变温度逐渐降低,且其相形貌逐渐由海岛结构经过双连续相结构到最后的相反转结构;室温下,随着定型剂用量的增加,织物表面定型剂的厚度及不均匀性增加,经过高温处理后,定型剂均匀分布在织物表面.定型剂用量对单轴向经编织物复合材料力学性能有较大影响,用量为20 g/m2时,复合材料体系的综合力学性能最优.
