摘要
中心开口的碳纤维复合材料层板的插层铺设非对称补强进行了孔边应力集中、应变分布、层间应力、损伤和强度特性的实验研究和理论分析，结果表明，本文采用的插层铺设非对称补强方式与顺序铺设补强方式相比，具有明显优异的补强效率，并能达到或超过对称补强的效率。
he effect of asymmetric submerged reinforcement on graphite epoxy composite laminates containing a hole was investigated analytically and experimentally on strain,stress concentration,damage and ultimate strength.A 3-D plate local/global finite element method was developed to analyse the response of reinforced hole laminates.It showed an exeellent effi-ciency of asymmetric submerged reinforcement,compared with the asymmetric separate rein-forcement,and also with the asymmetric separate reinforcement.
