| 摘 要： | 树脂与固化剂、促进刑等混合后组成树脂体系.单纯依赖实验方法测量树脂体系的黏度会造成人力和物力的巨大浪费,故引入化学流变模型来预测树脂黏度.简述了热固性树脂体系流变性能的实验流程,综述了适用于LCM工艺用热固性树脂体系的化学流变模型.这些模型包括双阿累尼乌斯模型、工程黏度模型、WLF模型、Fon-tana模型和Kiuna改性模型,同时评述了各模型的形式和特点.最后分析了现有化学流变模型的不足,指出综合考虑温度和固化程度因素、适用范围更广的化学流变模型将是未来的研究重点.

| Abstract: | A resin system is composed of resins,curing agents and accelerants.The only experimental method for the viscosity of the resin system can largely waste the manpower and material resources.Therefore,chemorheology models are applied to predict the resin viscosity.In this paper,experimental programs for those chemorheology properties of thermosetting resins are described,and then these chemorheology models of thermosetting resins for LCM process are reviewed,including dual-Arrhenius viscosity model,engineering... |
