摘　　要：本文对三种不同密度的ＳｉＯ_２空心微球／环氧树脂复合材料进行了静态压缩性能的实验测定和断口形貌分析，并对其结构形态与破坏过程作了微观适时观察。实验是在Ｉｎｓｔｒｏｎ材料试验机和带加载台的扫描电镜上进行的。除测得上述材料的弹性常数和抗压强度外，还根据微观观察的结果，对三种材料在压缩载荷作用下不同的破坏形态、变形特点、粘结强度和破坏模式等进行了初步分析和讨论。The static compressive characteristics of glass micro-ballon/epoxy composites ofthree different densities were experimentally determined and their fractographs wereanalysed.In-site observations of the micro-structure during the fracture process were carriedout.Experiments were done on lnstron testing machine and SEM with its loading stage. Theelastic constants and uItimate compressive strengths of the materials were determined.Basedon the results of the micro-observations, the fracture patterns, deformation features,bonding conditions and the way of fracture of the materials were discussed.
