摘要
采用DSC热分析技术和粘度测量手段,研究了海因树脂体系的固化特性和化学流变特性,建立了双阿累尼乌斯粘度模型。粘度模型预测的体系粘度变化规律与实验结果具有良好的一致性,模型可有效模拟树脂体系在不同工艺条件下的粘度行为,为复合材料成型工艺模拟分析以及工艺参数的准确制定奠定了基础。
In this paper,the rheological behavior of a hydantoin epoxy resin for resin transfer molding（ RTM） was studied with DSC analysis and viscosity experiments. A rheological model based on dual-Arrhenius equation was established to simulate rheological behavior of the resin. The estimated viscosity of the model was in good agreement with that of the experiments. The processing window of the resin system can be well determined for the process based on the developed model. The rheological model is important for processing simulation of resins and quality control of RTM processing for high performance composites.
