通过对端部引发缺陷层状纤维复合材料圆柱壳在轴向准静态和冲击压缩下的实验研究，分析其渐进压缩破损模式和破坏模式的形成机理．研究此类结构的缓冲性能．实验研究表明随着纤维铺设角度的改变其破损模式的主导形式与分层扩展强度、环向断裂强度和纤维与基体脱胶裂纹相关．它们的断裂韧度的高低决定结构的能量吸收能力 Through the experimental study of axially quasi-static and impact compression of the cylindrical shells with defects-induced layered fiber composites, the progressive compression failure mode and failure mode formation mechanism are analyzed. Study the buffering properties of such structures. Experimental studies show that with the change of the fiber laying angle, the dominant mode of failure mode is related to the stratified extension strength, circumferential breaking strength and the debonding cracks between the fiber and the matrix. Their fracture toughness determines the energy absorption capacity of the structure
