Abstract

A Time‐Temperature‐Transformation (TTT) diagram is created for the curing reaction of a DGEBA‐based epoxy resin. It results from a kinetic analysis performed by means of dynamical 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.This article is protected by copyright. All rights reserved

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。
