摘　　要：研究了RTM用酚醛环氧树脂体系的化学流变行为。采用示差扫描量热分析仪(DSC)考察了树脂体系的固化反应特性,通过流变仪研究了体系黏度与温度及时间的关系。基于树脂体系的化学流变特性,建立双Arrhenius黏度模型。研究表明,在恒温条件下,模型黏度的模拟值与实验结果具有良好的一致性。此模型可描述树脂体系在不同温度条件下的黏度变化趋势,为优化RTM工艺参数和保证产品质量提供了必要的技术基础和理论依据。The chemical rheological behavior of phenolic epoxy resin for RTM process was studied. The curing reaction characteristics of the resin system were investigated with differential scanning calorimeter （DSC）, and the relationship between viscosity and temperature and time was studied by rheometer. A double-Arrhenius viscosity model was established based on the chemical rheological properties of the resin system. The re- sults showed that the simulation value of the model viscosity was good in consistency with the experimental result under constant temperature condi- tion. This model could describe the trend of viscosity change of resin system under different temperature conditions, and provide necessary technical foundation and theoretical basis for optimizing RTM process parameters and ensuring the product quality.
