This paper presents the usage of spark plasma sintering (SPS) as a method to obtain aluminum-expanded perlite syntactic foams with high porosity. In the test samples, fine aluminum powder with flaky shape particles was used as matrix material and natural, inorganic, granular, expanded perlite was used as a space holder to ensure high porosity (35−57%) and uniform structure. SPS was used to consolidate the specimens. The structures were characterized by scanning electron microscopy and compression tests. Energy absorption (W~7.49 MJ/m3) and energy absorption efficiency (EW < 90%) were also determined.
本文介绍了使用放电等离子烧结（SPS）法制备高孔隙率的膨胀珍珠岩增强铝基复合泡沫材料。在测试样品中，使用片状细铝粉作为基体材料，天然无机粒状膨胀珍珠岩作为造孔剂，以确保高孔隙率（35%-57%）和均匀结构。采用SPS对试样进行固结。通过扫描电子显微镜和压缩试验对结构进行表征。还测定了能量吸收（W~7.49 MJ/m3）和能量吸收效率（EW<90%）。
