A novel epoxy resin (EP)/hollow glass microsphere modified (g-HGM) composite was successfully prepared. Studies showed that the water absorption rate of the g-HGMs/EP composite is lower than pure HGMs/EP and HGMs-KH550/EP composites, while the compressive strength of g-HGMs/EP composites could be increased. The enhanced interfacial adhesion between EP and g-HGMs played an important role to improve the compatibility of the two components. The g-HGMs show little effect on density (relative to HGMs) on the g-HGMs/EP composites, which can perform better than the HGMs/EP composites being used in marine environments. It was found that the optimal content of 4,4’-diphenylmethane diisocyanate in the epoxy component was 20 wt%.

成功制备了一种新型的环氧树脂（EP）/空心玻璃微球改性（g-HGM）复合材料。研究表明，g-HGMs / EP复合材料的吸水率低于纯HGMs / EP和HGMs-KH550 / EP复合材料，但可以提高g-HGMs / EP复合材料的抗压强度。EP和g-HGM之间增强的界面粘合性对改善两个组分的相容性起着重要作用。g-HGMs对g-HGMs / EP复合材料的密度几乎没有影响（相对于HGMs），其性能优于海洋环境中使用的HGMs / EP复合材料。发现在环氧组分中4，4′-二苯基甲烷二异氰酸酯的最佳含量为20重量％。
