Testing of energy absorption capability of sandwich structures based on metal foams for design of protective helmets

Popis výsledku v původním jazyce

Purpose of this study is investigation of energy absorption capability of the sandwich structuresncomposed of combination of polystyrene and metal foam element and their suitability as newnstructure for design of protective helmets. Two types of the metal foams were experimentally tested and evaluated: 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. Acceleration/time history was used for the Head Injury Criterion (HIC) calculation. HIC is the significant parameter which expresses probability of head injury arising from an impact. Moreover, measured and derived characteristics are compared with pure EPS samples to obtain comparison of deformation beha
