| 摘 要： | VIMP(真空注射模塑)工艺以其低成本、环保和适于大型制件一次整体成型等优点得到了广泛应用.本文对VIMP工艺用低粘度环氧树脂体系进行了固化反应动力学和粘度分析,确定了最佳固化温度,建立了树脂体系的流变模型,模型分析结果与实验结果吻合较好,根据此流变模型预报了工艺窗口.并进行了VIMP模塑板材工艺实验,测试了板材的纤维体积含量和力学性能.

| Abstract: | VIMP(Vacuum Infusion Molding process) is widely used because it has many advantages,such as low cost,environmental protection and suitable for holistic mould of large composite structures.Curing reaction and rheological behavior of a low viscosity epoxy resin system were studied by DSC and viscosity experiments and an optimum curing temperature was found for the resin system.Based on Dual-Arrhenius equation,a rheological model of the resin system was established,and predicted viscosity values of the resins ... |
