Mechanical Properties of Stainless Steel Cellular Materials with Polyurethane

Abstract

Metallic cellular materials containing a polymer were fabricated by the polymer penetrating into cells of the metallic cellular material. The stainless steel cellular materials were selected for use as the cellular material and polyurethane resin was selected as the penetrated polymer. The mechanical properties of this material were measured. The results of the compressive tests showed that the stainless steel cellular material containing the polyurethane has different stress-strain curves from that without any polymer. These results also showed that the stainless cellular material containing polyurethane has a high-energy absorption. The shock absorbability of this material is higher than that of the polymer and lower than that of the stainless steel cellular material.
