Prediction Simulation and Process Optimization for Curing Over-temperature of Composite Foam Sandwich Structures
针对超厚复合材料泡沫夹层结构固化超温问题,基于包含模具热影响的多场耦合仿真模型进行预测与工艺优化.模型验证最大相对误差低于 2％;结合响应面代理模型(R2=0.91),分析了铺层数、构件宽度与升温速率对最高固化温度的耦合作用,发现"热垒效应"显著,铺层超过 15 层后热积累急剧 增 强.通过优化工艺,将升温速率从 2℃/min 降至 1℃/min 可使峰值温度降低21.53℃,超温改善率达76％.提出了"无超温临界厚度"(超过此厚度易超温)与"临界散热宽度"(超过此宽度散热效益锐减)等关键设计参数,为控制固化超温提供了理论支撑与工程可行方法.
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.
