摘　　要：本文采用可溶石膏型预制块,通过加压渗流的方法制备了泡沫纯铝、泡沫ZL101合金和泡沫ZL102合金,并通过准静态压缩实验研究了3种不同基体材料的泡沫铝的压缩行为及吸能性能。结果表明:通过石膏型渗流法制备的开孔泡沫铝合金的孔隙率可以达到85%～93.5%;泡沫铝基体材料的力学性能对泡沫铝压缩力学性能有重要影响;泡沫ZL101合金能够吸收最多的能量,且在较大的应力、应变范围内对材料起到缓冲保护作用。The polymeric reticular sponge was choosen as the mother plate to make the soluble gypsum mould,and after that,through infiltrating casting to fabricate three kinds of open-cell aluminum foam,which are pure aluminum foam,ZL101 aluminum alloy foam and ZL102 aluminum alloy foam.The compressive behaviors and energy-absorption capacities of those different kinds of foams were investigated by the quasi-static compression test.The experimental results indicate that the porosity of the aluminum foams made by the gypsum mould infiltrating casting are 85%～93.5%;The matrix properties have notable effects on the mechanical behaviors of foams;The ZL101 aluminum alloy foam can absorb the most energy and also can protect the materials in the larger ranges of stress and strain.
