摘要:
以牌号为K20和HGS8000X的空心玻璃微珠为环氧树脂的填充材料，采用模压法制备了环氧树脂基复合材料，对其上、中、下三部分的密度、压缩强度及微观结构进行了测试和观察，比较了微珠的不同体积比对复合材料性能的影响。结果表明，不同粒径的空心玻璃微珠混合填充，有利于复合材料密度的降低，而且采用混合微珠制备的复合材料具有较好的性能均一性；微珠堆积系数越大，材料性能均一性越好。
The epoxy resin matrix composite which was filled with hollow glass microspheres (HGMs) was prepared by molding. Two kinds of HGMs were K20 and HGS8000X. By testing and observing the density, compression strength and microstructure of different parts of the composite, the impact of volume fraction of HGMs on properties of the composite was compared. The results showed that: it was beneficial to get a lower density by mixing HGMs of different diameters; the homogeneity of the composite which was prepared by mixed HGMs was better; the higher accumulation coefficient of the HGMs was, the better homogeneity of the composite was.
