为探究空心微珠填充量对树脂基深水浮力材料压缩性能的影响以及材料压缩破坏机理,基于Mori-Tanaka及Turesanyi方法对空心微珠填充环氧树脂基深水浮力材料的有效弹性模量及压缩强度进行了理论预测.制备了空心微珠填充环氧树脂基深水浮力材料,对不同空心微珠填充比的材料体系进行了单轴压缩试验,并通过扫描电镜观察了材料断裂面微观形貌.结果表明：随着空心微珠填充量增加,材料体系耐压强度降低,模量上升,且实验结果与理论预测吻合情况较好;空心微珠破损是深水浮力材料破坏的根本因素.
To investigate the influence of hollow glass microsphere contents on compression property of resin matrix deep-water buoyancy materials and damage mechanism under compression, Mori-Tanaka and Turesanyi method were used to predict the effective elastic modulus and compressive strength of buoyancy material in this paper,respectively. The buoyancy materials were prepared by filling hollow glass microsphere with different contents into epoxy resin. Compressive tests of polyurethane syntactic foams with different volume fractions of hollow glass microspheres were carried out, and the results indicated that the compression strength decreased and the modulus increased with the increasing of volume fractions of hollow glass microspheres. The theoretical prediction agreed well with the test results. Moreover,the microstructures showed that the hollow beads break- age was responsible for buoyant materials failure.
