Experimental study on the quasi-static compression behavior of multilayer aluminum foam sandwich structure

The axial compression responses of multilayer aluminum foam panels (MLAF) and multilayer sandwich panels (MLAFS) with 5052 Al alloy interlayer plates were experimentally investigated under quasi-static compression condition. The influence of aluminum foam (AF) core density, stacking number and the i...

Description
Summary:The axial compression responses of multilayer aluminum foam panels (MLAF) and multilayer sandwich panels (MLAFS) with 5052 Al alloy interlayer plates were experimentally investigated under quasi-static compression condition. The influence of aluminum foam (AF) core density, stacking number and the interlayer plates in MLAFS structures were discussed extensively. Compared with bulk AF, the results indicate that the mechanical properties of MLAF structures are slightly decreased while the compressive resistance of MLAFS structures is obviously enhanced. The presence of Al alloy interlayer plates changes the deformation mode of MLAFS structures and induces collapse in sequence by layer. The effect of stacking number on the compressive behavior of MLAFS structures varies with AF core density and the optimum MLAFS structure was summarized in view of the energy absorption capacity and compressive deformation degree. •Compared with bulk aluminum foam, the compressive behavior of multilayer aluminum foam sandwich panels (MLAFS) is improved.•The presence of Al alloy interlayer plates changes the deformation mode of MLAFS structures.•The compressibility of MLAFS structures is well described by empirical equations.•The optimum multilayer sandwich structure was summarized in view of energy absorption.
