Purpose of this study is investigation of energy absorption capability of the sandwich structures composed of combination of polystyrene and metal foam element. Two types of the metal foams were experimentally tested: Alporas (Shinko Wire Ltd., Japan) and Aluhab (Aluinvent Plc., Hungary). Samples of the sandwich structure are composed of two layers: bottom expanded polystyrene (EPS 200S) layer and upper metal foam layer which are glued together. Prepared samples are tested using a drop tower experiment to measure sample response (acceleration, reaction force) at different strain rates and energies. From acceleration/time history the Head Injury Criterion (HIC) is calculated. Measured and derived characteristics are compared with EPS samples.
