Sažetak
Open-cell cellular structures are being increasingly used in automotive, railway, ship and aerospace industry as crash energy absorbers. The reported research was aimed to investigate the influence of the second phase filler material (i.e. the elastic filler material) on behavior of regular open-cell cellular structure under quasi-static and dynamic compressive loading with the purpose to determine ways how to increase the crash energy absorption level of cellular materials. Only regular open-cell cellular structures were considered in this study to achieve certain repeatability during experimental testing. Two base materials of cellular structures were considered: (i) aluminum alloy and (ii) polymer. The quasi-elastic silicon was used as a filler. The cellular structure cells were filled with the silicon in a vacuum chamber. A servo-hydraulic testing machine was used to determine mechanical properties and behavior of open-cell cellular structure with and without the silicon under quasi-static and dynamic compressive loading conditions. The experimental results show a significant influence of the strain rate. An increase of Young’ s modulus and yield stress was observed in cellular structures filled with silicon filler. Additionally, such composite structures exhibited certain crash energy absorption increase, which was more pronounced in case of the polymer cellular structure.
