CURING KINETICS OF EPOXY RESIN FOR WIND-POWER BLADES USING ISOTHERMAL DSC

Abstract

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
