以环氧树脂(E-51)为基体,593为固化剂,牌号为S38HS、IM16K和IM30K的3种中空玻璃微球(hollow glass microspheres,HGMs)为填料,制备了低密高强的固体浮力材料。通过密度测试和准静态单轴压缩实验,研究了HGMs的添加类型以及添加量对材料的体积密度,抗压强度、弹性模量和断裂性能的影响。结果表明:当加入不同类型的HGMs时,材料的密度为0.641~0.992 g/cm3,抗压强度为58.932~118.548 MPa,弹性模量为1.42~2.068 GPa,比压强为91.94~137.46 MPa·(g/cm3)-1和比弹性模量为1.933~2.462 GPa·(g/cm3)-1。当添加不同类型的HGMs时,试样呈45o剪切破坏的特点;断裂面,有“水纹”的特点。
Three kinds of hollow glass microspheres (HGMs) with epoxy resin (E-51) as matrix, 593 as curing agent, S38HS, IM16K and IM30K were used as filler to prepare low density and high strength solid buoyancy material . Through the density test and quasi-static uniaxial compression experiments, the effects of the type of HGMs added and the amount added on the bulk density, compressive strength, elastic modulus and fracture properties of the material were studied. The results showed that when the different types of HGMs were added, the density of the material was 0.641-0.992 g / cm3, the compressive strength was 58.932-118.548 MPa, the elastic modulus was 1.42-2.08 GPa, and the specific pressure was 91.94-137.46 MPa · (g / cm3) -1 and a specific elastic modulus of 1.933-2.462 GPa · (g / cm3) -1. When adding different types of HGMs, the specimen is 45o shear failure characteristics; fracture surface, “water pattern ” features.
