| 摘 要： | 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

| Abstract: | The broken process of fiber composite laminated cylindrical shells under axial loading is investigated experimentally. It is found that the broken mode of specimens changes with the fiber angle of composites. Some problems involving fracture toughness and energy absorption of composites are discussed. |

| Keywords: | fiber composite cyclindrical shell axial compression progressive damage |
