Abstract: The lowvelocity impact tests on the aluminum foam sandwiches(AFS) with a metallic bonding and adhesive bonding between face sheets and foam core were carried out. The mechanical response and failure mode of two kinds of AFS was studied. The results showed that the two kinds of AFS have the ability of energy absorption, but the buffer time of AFS with a metallic bonding between face sheets and foam core is longer than that of the adhesive structure. With the increase of load, the yield load and platform load of the AFS with a metallic bonding between face sheets and foam core increase and the buffer time reduces, showing an obvious strain rate effect during the test. The failure modes of the AFS with a metallic bonding between face sheets and foam core are core shear, core compaction and panel bending deformation.

Key words: aluminum foam sandwichs(AFS), lowvelocity impact, failure mode, yield load, metallic bonding
