| 摘 要： | 制备了空心玻璃微珠 (HGM )填充环氧树脂复合材料 ,对材料进行了单轴静态压缩实验。研究了HGM的粒径和体积分数 (Vf)对材料压缩性能的影响 ,研究发现 ,Vf增大 ,材料中HGM外部空气泡的含量增大 ;材料的压缩强度和压缩模量可在 5 0～ 10 0MPa和 1.5 0～ 1.80GPa之间调节 ;材料断裂应变较小 ,用扫描电镜观察了其结构形态和破坏形式 ,断裂面与应力方向约成 45°角 ,破坏主要由HGM的破裂引起 ;HGM粒径减小 ,材料压缩强度增大 ;Vf 增大 ,压缩强度减小 ,压缩模量先增大后减小 ,断裂应变减小。用改进Turcsanyi方程对压缩强度进行了模拟计算 ,材料的密度与计算值基本一致

| Abstract: | Uniaxial static compression behavior of composites of epoxy resin (E-51) and hollow glass microspheres (HGM) was investigated.As the volume fraction of HGM (V-f) increased,both compressive strength and break strain decreased,the compressive modulus increased first and decreased after a maximum.The fractured surface was observed using SEM and found that the fracture of the composite was caused by the breaking of HGM.The compressive strength was modeled with modified Turcsanyi equation,the calculated values agreed with the experimental data. |
