摘要/Abstract

摘要： 应用流变仪和DSC分析技术,系统研究了促进剂含量对一种用于大型碳纤维复合材料结构件真空导入成型的环氧树脂体系的影响。对促进剂含量分别为0.5%、1.0%和1.5%的环氧树脂体系,分别进行了粘度特性、工艺窗口、固化特性和基本力学性能的分析。该树脂体系的最佳灌注温度并未随促进剂含量增加而变化,适用期、完全固化所需的温度和时间均随促进剂含量的增加而降低。增加促进剂含量可以降低固化温度,并保证浇铸体的力学性能基本不受影响,从而可以在普通模具中应用该环氧树脂体系。

关键词: 环氧树脂, 流变特性, 碳纤维, 真空灌注, 工艺窗口

Abstract: Impacts of accelerator content on epoxy resin were studied systematically by rheometer and DSC analysis for carbon fiber composites in large structural applications by vacuum infusion moulding process. The viscosity behavior, process window, curing characteristics and elemental mechanical properties were analyzed for this epoxy resin with different accelerator content of 0.5%, 1.0%, 1.5%. The optimal infusion temperature didn't change any as the accelerator content increases, but the pot life was obviously shortened. The temperature and time required for complete curing decreased with the increasing of accelerator content. The mechanical properties are almost not affected. Thus, this epoxy resin can be used in ordinary mould.

Key words: epoxy resin, rheological behavior, carbon fiber, vacuum infusion, processing window
