中文摘要：

为获得一种新型氧化锌纳米晶须辅助增强环氧树脂基复合材料的准静态和动态压缩力学性能，采用万能实验机和分离式Hopkinson压杆装置为加载手段，对该复合材料层合板厚度和平面内两方向的准静态和动态压缩性能进行实验研究；借助扫描电镜对该复合材料断口损伤形貌进行表征．实验结果表明：在动态加载下，该复合材料具有明显的非线性本构关系和应变率强化效应．材料在厚度方向的破坏以剪切破坏为主，在平面内方向的破坏以分层破坏为主，其厚度和平面内两方向的压缩破坏具有完全不同的破坏机制．

英文摘要：

To understand the quasi-static and dynamic compressive mechanical properties of a kind of glass-fiber polymer composites embedded with ZnO whiskers, several quasi static and dynamic compression experiments in the normal and in-plane direction were conducted, by means of universal test machines and Hopkinson bars technology respectively. SEM images of fracture of specimen were achieved in each direction. The experimental results showed that the materials had obvious non-linear constitutive relation and strain rate strengthening effect. Specimens had various failure modes, which failed as shear fracture in the normal direction and as de-lamination and splitting failures, respectively.
