摘要
开发了一种VARI工艺用高温环氧树脂5284VARI,通过DSC(差示扫描量热仪)测试了该树脂的固化反应特性,利用流变仪分析了该树脂的成型工艺特性,并通过力学试验机测试了树脂及其复合材料的力学性能。结果表明,该树脂体系在成型温度下具有粘度低和成型时间长的特点,适用于液态成型工艺,且该树脂具有良好的耐湿热环境性能。
A high temperature cured epoxy resin system（ 5284VARI） moulding by VARI was designed. Curing reaction characteristics of this epoxy resin were tested by DSC（ Differential Scanning Calorimeter）. The operation characteristics of this epoxy resin system were analysed by rheometer. The mechanical properties of this resin system and its composite were tested by mechanical testing machine. The results demonstrated that 5284 VARI epoxy resin system has low viscosity on moulding temperature and can maintain long duration. This resin system is appropriate for moulding composites by VARI. Besides,this epoxy resin has good properties under wet-and-hot conditions.
