改性BMI树脂固化过程的温度控制优化
Optimal Temperature Profiles for Modified BMI Resin Matrix in Curing Process
摘要
Abstract
A three-dimensional model considering the heat conduction equation and the cure kinetics model is used to simulate the resin film infiltration (RFI) curing process of the modified bismaleimide (BMI) resin matrix. The finite element method and the finite difference method are used to discretize the governing equations. In order to measure the quality of cure, two new control parameters are used in the optimal control of temperature for the curing process. The numerical results show that both the temperature and the cure degree within the component are higher than those on the surface; the dwell temperature and the starting time have great effects on the uniform of the curing degree and the temperature. The simulation results play a significant role on planning the optimal curing process.关键词
