| 摘 要： | 本文对风机叶片用环氧树脂体系的流变性能进行了研究,在粘度实验的基础上,依据双阿累尼乌斯方程建立了与实验数据较为吻合的流变模型。结果表明,两种树脂体系的粘度随温度变化情况基本一致,在23～50℃范围内,其粘度都低于300mPa.s,且低粘度保持时间大于30min,符合风机叶片真空成型对树脂低粘度的要求。所建立的粘度模型可有效预测和模拟树脂体系在不同工艺条件下的粘度行为,揭示树脂体系的优化工艺参数和低粘度平台工艺窗口,为合理拟订工艺参数和保证产品质量提供必要的科学依据。

| Abstract: | The rheological behavior of epoxy resin system for wind turbine blade was studied with 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 prediction determined from the dual-Arrhenius equation was in good agreement with experimental data.The results showed that: both resin viscosity changes with temperature is consistent,the viscosity is lower than the 300mPa · s range from 23℃ to 50℃,and the low viscosity maintaining time is more than 30min.The established viscosity model can effectively predict and simulate the viscosity behavior of resin systems under different conditions,reveal the optimized processing parameters and low viscosity platform process window for the resin system,and provide the necessary scientific basis to ensure a reasonable product quality. |
