Abstract

A time–temperature-transformation diagram is created for the curing reaction of a diglycidylether bisphenol A (DGEBA)-based epoxy resin. It results from a kinetic analysis performed by means of dynamical differential scanning calorimetry (DSC) measurements; a gelation curve determined with isothermal and dynamical rheological tests; and a vitrification curve obtained from temperature-modulated dynamic DSC measurements. The resulting diagram is validated by comparison of isothermal measurements with the corresponding calculated curves.

环氧胺体系的时间-温度-转化（TTT）固化示意图

为一种基于 DGEBA 的环氧树脂的固化反应绘制了时间-温度-转变（TTT）图。该图由以下部分组成：通过动态 DSC 测量进行的动力学分析；通过等温和动态流变测试确定的凝胶化曲线；以及通过温度调制动态 DSC 测量获得的玻璃化曲线。通过将等温测量结果与相应的计算曲线进行比较，验证了得出的图表。本文受版权保护。
