Abstract

PurposeMetal foams are a structural and functional composite materials that have received wide attention due to their specific structures and properties. The aim of this study is to investigate the mechanical properties of syntactic foam by using expanded silica gel with the spacer technique.Design/methodology/approachIn this research paper, the vacuum casting production method was used to produce metal syntactic foams including AlSi12 and AlSi8Cu3 matrix and expanded silica gel fillers with diameters of 2–4.75 mm and 4.75–5.6 mm.FindingsAs a result of the study, it was observed that as the foam densities increased, the compressive strength values of the samples increased due to the increasing volume fraction of the metallic matrix. Samples with the AlSi12 matrix showed higher compressive strength than samples with the AlSi8Cu3 matrix.Originality/valueThe originality of the study is the comparison of two different main matrix alloys (AlSi12 and AlSi8Cu3) and different pores using expanded silica gel.

膨胀硅胶作为空心球材料在不同铝合金基复合泡沫中的综合研究

金属泡沫材料是一种结构和功能复合材料，因其特殊的结构和性能而受到广泛关注。本研究的目的是利用膨胀硅胶和间隔剂技术研究复合泡沫的力学性能。本研究采用真空铸造法制备了直径为2 ~ 4.75 mm和4.75 ~ 5.6 mm的AlSi12、AlSi8Cu3基体和膨胀硅胶填料等金属复合泡沫材料。研究结果表明，随着泡沫密度的增加，试样的抗压强度值随着金属基体体积分数的增加而增加。AlSi12基体样品的抗压强度高于AlSi8Cu3基体样品。本研究的独创性在于比较了两种不同的主基体合金(AlSi12和AlSi8Cu3)和使用膨胀硅胶的不同孔隙。
