热固性树脂基复合材料固化变形解析预测研究进展

A review of analytical prediction of cure-induced distortions in thermoset composites

在外部成型条件和内部材料各向异性的影响下,脱模后复合材料构件不可避免的产生固化变形,解析预测方法可以快速的预估复合材料的固化变形并能解释其潜在的变形机制,因而被广泛研究。本文介绍了热固性复合材料固化变形的产生因素和来源,并重点了详述了平板和曲型复合材料构件固化变形解析预测方法的最新进展,并分析其优缺点,为复合材料固化变形预测提供方向和参考。最后简要讨论了当前复合材料固化变形解析预测的主要发展方向。

It is inevitable to induce the cure-induced distortions in thermoset composites due to extrinsic processing conditions and intrinsic materials anisotropy.Analytical solution could provide a quick prediction and explain underlying mechanisms of cure-induced distortions in composites,therefore it is increasingly investigated.This paper aimed at introducing the factors and sources giving rise to the cure-induced distortions in thermoset composites,with an emphasis being placed on state-of-art investigation on the analytical solutions of cure-induced distortions in flat and curved composite parts,and analyzing their merits and demerits to offer a direction and reference to the estimate of cure-induced distortions in composites.In the end,the future development of cure-induced distortions in composites was discussed briefly.
