【摘要】 用建立在边界层理论分析基础上的层压板孔边层间应力分析方法,计算了层间加胶膜复合材料层压板的孔边应力。发现Intelleaf的加入不会影响孔边层间应力的分布,只删昙间应力明显下降。Interleaf加在不同层间其软化的效果是不同的。更多还原

【Abstract】 In this paper ,the stress distribution along a hole boundary in an interleaved laminate composite was calculated, by using an analytical solution of interlaminar stresses based on the boundary-layer theory. It was found that the interleaf has no effect on the interlaminar stress distribution, but it will reduce the amplitude of the interlaminar stresses significantly. The interleaves between different plies have different effect on the softening of interlaminar stress.更多还原
