热固性树脂固化动力学模型简化的新方法
New Simplification Method of Thermosetting Resin Curing Kinetic Models
摘要
Abstract
Temperature-time-transition (TTT) diagram is a useful tool for analyzing and designing the curing process, which has an important research value. The traditional iso-conversional curves drawing process in TTT diagram is a complicated process which is time consuming and costly. The relationship of temperature, time and degree of cure is controlled by the curing kinetic equation. From the perspective of the curing kinetic equation, studying the iso-conversional curves with the numerical simulation method is a novel method which can reduce both time and cost. For two kinds of resin curing kinetics models, the resin degree of cure is simulated, and the simulation program has been verified. Based on this work, the iso-conversional curves of two kinetic models are plotted and the relationship of the temperature, time and degree of cure is discussed. The result shows that a negative linear relationship exists between the temperature and the logarithm of the time. Then by curve fitting method a relatively simple relationship of the iso-conversional curves is obtained which can be used more conveniently in engineering practice without cumbersome computation.关键词
