本文基于复合材料固化过程材料状态的变化,建立了多层次的固化模拟方法,模型考虑了结构与工艺的影响因素,以热压罐成型T800/环氧树脂体系复合材料结构为例,着重分析了结构因素对固化变形的影响,采用从层合级基础结构,过渡到C形结构,再过渡到双工形加筋壁板结构,最终逐渐接近实际复杂结构积木式方法,给出了铺层对称性、结构尺寸、间距以及加筋壁板腹板高度对固化变形的影响规律。
Based on the change of material state during the curing process of composite materials, a multi-level curing simulation method is established. The model considers the factors that affect the structure and process. Taking the T800 / epoxy resin composite structure as an example, Structural factors on the impact of curing deformation, using the transition from the laminated foundation structure to the C-shaped structure, and then transition to the duplex reinforced stiffened panel structure, and finally gradually close to the actual complex structure of the building block method, given the ply symmetry The influence of solidification deformation on the structure, size, spacing and web height of stiffened webs.
