在粘度实验的基础上，根据双阿累尼乌斯方程对用于RTM工艺的双马来酰亚胺树脂体系的化学流变特性进行了研究，建立了树脂体系的流变模型。通过DSC热分析实验研究树脂体系的固化反应规律，验证了双阿累尼乌斯模型。研究表明，模型与实验结果具有良好的一致性。模型可揭示树脂体系在不同工艺条件下的粘度变化规律，定量预报RTM工艺树脂的低粘度平台工艺窗口，为合理制定RTM工艺参数、保证产品质量和实现工艺参数的全局优化提供必要的科学依据。rn“,”The rheological behavior of bismaleimide resin for resin transfer molding(RTM) was studied with DSC analysis and viscosity experiments.A rheological model based on the dual-Arrhenius equation was established and used to simulate the rheological behavior of the resin.The model predictions determined from the dual-Arrhenius equation were in good agreement with experimental data.The processing window of the resin system can be well determined based on the developed model.The rheological model is important for processing simulation and quality control of RTM processing for high performance composites.
