Abstract
Energy-absorbing materials represent an important group of products in the field of increasing the safety of citizens. Research and development including physical properties testing leads to improvement of these materials and protective constructions. Two types of fillers were chosen for testing: macro and microfillers, together with a two-component polyurethane binder. Different recipes of energy absorbing materials were tested and the resulting physico-mechanical properties, namely bulk density and flexural, compressive and impact strength, are listed in this article. Deformation curves were recorded during pressure loading of materials with macrofillers incorporated. Based on these curves, the rate and mode of energy absorption can be predicted. Most samples underwent the Split-Hopkinson pressure bar test which was the crucial method for the determination of impact energy absorption.
