摘要/Abstract

摘要： 为研究风电叶片用环氧树脂的固化反应进程,采用等温DSC法测得了树脂体系在60 ℃、70 ℃、80℃下的等温放热曲线,并通过Matlab拟合功能对n级动力学模型、自催化模型和Kamal模型三种基本模型进行了分析,结果表明该树脂体系符合Kamal模型。在对Kamal模型计算结果与实验数据的对比中发现,计算结果在后段出现了偏高的现象,因此必须考虑扩散效应的影响。在对两个扩散控制Kamal模型的对比中可以发现Chern模型结果较优,该模型对转折点附近的拟合结果较为符合实际。

关键词: 环氧树脂, 等温DSC, 固化动力学

Abstract: In order to study the curing reaction process of epoxy resin for wind-power blades, isothermal DSC was used to measure heat flow curve of resin system at 60 ℃, 70 ℃, 80 ℃, and three kinds of basic models fitted by Matlab function of n-order dynamics model, the autocatalytic model and Kamal model are analyzed. It turns out that the resin system conforms to the Kamal model. By comparing calculation results with the experimental data, it is found that the calculation results are always higher than the experimental data. Therefore, the effect of diffusion effect must be considered. When we compare the two diffusion control Kamal models, we found that Chern fitting results are better than another. Finally, the curing kinetics equation was obtained by using the correctional Kamal model.

Key words: epoxy resin, isothermal DSC, curing kinetics
