复合材料泡沫夹层结构固化超温预测仿真及工艺优化
Prediction Simulation and Process Optimization for Curing Over-temperature of Composite Foam Sandwich Structures
摘要
Abstract
To address the curing overheating in ultra-thick composite foam sandwich structures,a multi-physics model incorporating mold thermal effects is established to predict curing overheating and optimize its process.Validated with a maximum relative error below 2％,the model was combined with a response surface surrogate(R2=0.91)to analyze the coupled effects of ply count,part width,and heating rate on peak curing temperature.A significant"thermal barrier effect"was observed,especially the heat accumulation is intensifying sharply beyond 15 plies.Reducing the heating rate from 2℃/min to 1℃/min can lower the peak temperature by 21.53℃(76％improvement).Key design parameters-"critical overheating-free thickness"(beyond which overheating is likely)and"critical heat dissipation width"(beyond which cooling benefit diminishes)-were proposed,providing theoretical support for controlling curing overheating engineering.关键词
