摘要
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。
In this paper,a multi-level simulation model is developed based on the fact of property variation of the composites during the cure process.Take T800/epoxy resin system composite structure as an example,the effect of structural factor on cure deformation was studied in a building block approach,it is means first focus on laminate structure and then C shape stiffed plate,thirdly studied on the double I beam stiffed plate and finally concentrated on the full-size composite part.The effects of symmetry of layup,size,the distance and height of the stiffed plate on cure deformation were carefully elaborated during the analysis.
