从聚合物的结晶到热固性树脂的固化-Avrami理论在研究热固性树脂固化过程中的应用
From the Crystallization of Polymers to the Cure of Thermosets -Application of Avrami Theory in the Study of Cure of Thermosets
-
摘要: 热固性树脂的固化与聚合物的结晶都伴随着“成核”与“生长”,具有许多相似之处,因此具有明确参数物理意义的Avrami相变理论可以被用作研究固化过程的唯象模型。介绍了Avrami相变理论及其教学形式-Avrami方程的物理基础及其在研究热固性树脂固化过程中的应用。Abstract: The cure of thermosets and the crystallization of polymers from melt have many resemblances, both accompanied with two stages of nucleation and growth. Consequently, the Avrami theory of phase change with clear physical meanings for each parameter can be
