摘　　要：为了准确地预测Elium树脂的放热性能,基于瞬态非线性热传导方程的树脂固化模型,利用Abaqus仿真软件,建立了Elium树脂固化有限元模型,并对不同厚度Elium树脂的固化过程进行模拟和实验验证。结果表明固化温度的模拟计算结果与实验结果一致,固化峰值温度随着树脂厚度的增加呈现非线性增加趋势,当固化峰值温度接近100℃时,树脂中产生气泡,为优化Elium复合材料成形工艺提供了理论依据。In this paper,the curing process of Elium resin of various thicknesses was simulated and experimentally verified using Abaqus simulation software.This was done in order to accurately predict the exothermic behavior of Elium resin.A finite element model of Elium resin curing was developed based on the transient non-linear heat transfer equation of the resin curing model.The findings demonstrate that the simulation results for the curing temperature agree with the experimental findings,and the peak curing temperature exhibits a non-linear increasing trend as resin thickness increases.When the peak curing temperature approaches 100℃,resin bubbles are produced,providing a theoretical foundation for optimising the Elium composite curing process.
