摘要: 本文以发泡聚苯乙烯(EPS)颗粒为填充材料，以环氧树脂为基体，采用真空辅助模压成型方法制备了具有不同复合比的复合材料，研究了材料的密度、压缩强度及吸水率与材料复合比的关系。结果表明，EPS颗粒/环氧树脂复合材料呈现以环氧树脂为骨架的EPS多面体嵌合结构，其性能强烈依赖于材料的复合比。选用0.75~0.85的复合比，可以得到密度为0.3 ± 0.01 g/cm3，吸水率小于0.3%，适用于100米水深的固体浮力材料。
Abstract: In this paper, composite materials with different compounding ratios are prepared via vacu-um-assisted compression molding method using expanded polystyrene (EPS) particles as filler and epoxy resin as matrix. The relationships between the compounding ratio and the density, compressive strength and water absorption of the composites are investigated. The results showed that the as-prepared composites possessed a mosaic structure with epoxy resin as the backbone, and their properties are strongly dependent on the compounding ratio. Using a compounding ratio of 0.75 to 0.85, a composite with a density of 0.3 ± 0.01 g/cm3 and water absorption of less than 0.3% can be obtained. This composite is suitable as solid buoyancy material for using under 100 meters of water.
