中文摘要：

根据有效应力准则和达西定律,结合曲线坐标系,构建了曲面复合材料构件固化过程中的树脂流动和纤维压实控制方程;建立了基于AS4/3501-6纤维树脂体系的层合板仿真模型,并将分析结果与实验数据对比,验证了模型的有效性;研究了曲率参数对复合材料构件非等温固化压实的影响规律,比较和分析了曲率参数与厚度和压力参数耦合作用下对树脂流动行为的影响机制。结果表明：构件曲率参数会对树脂分布产生一定影响,曲率越大,树脂分布的非均匀性越大;曲率参数的作用表达受到厚度与压力参数的影响,当厚度与压力较小时,对曲率的影响不明显。

英文摘要：

Based on the effective stress principle,Darcy＇s law and the curvilinear coordinate system,resin flow and fiber compaction control equation of curved laminated composite structures were developed.The laminate simulation model based on AS4/3501-6fiber resin system was established and the validity of the model was verified by comparing analytical results with experiment data.The research had been carried on the rule about the influence of curvature parameters on the consolidation of composite structures under non-isothermal conditions,and the influence mechanism of the resin flow behavior which was affected by curvature-thickness and curvature-pressure coupling parameters was compared and analyzed.The results show that the curvature parameter of structures can influence the distribution of resin,and the bigger the curvature is,the less uniform the distribution of resin is.The expression of effect of curvature parameter is affected by the parameters of thickness and pressure,and the effect on the curvature is minor when thickness and pressure is small.
