The aim of the present activity was the manufacturing of enhanced closed-cell aluminum foam based samples for industrial applications such as security systems in the automotive field (e.g., anti-intrusion bars); as reinforcement, that also constitutes a flexible die, a stainless steel wire mesh was considered. The Powder Compact Melting technique was used for producing cylindrical samples, starting from a commercial foam precursor and replacing the conventional dies by the wire mesh, the last with the additional effect of foam reinforcement. Quasi-static compression and three-point bending tests were performed to determine the mechanical behavior of these reinforced and lightweight samples, in order to compare their properties with the ones of plain foam samples. Finally, a component with a complex geometry was manufactured, aiming to evaluate the chance to use the proposed flexible dies as metal foam reinforcements in many instances.

Abstract
The aim of the present activity was the manufacturing of enhanced closed-cell aluminum foam based samples for industrial applications such as security systems in the automotive field (e.g., anti-intrusion bars); as reinforcement, that also constitutes a flexible die, a stainless steel wire mesh was considered. The Powder Compact Melting technique was used for producing cylindrical samples, starting from a commercial foam precursor and replacing the conventional dies by the wire mesh, the last with the additional effect of foam reinforcement. Quasi-static compression and three-point bending tests were performed to determine the mechanical behavior of these reinforced and lightweight samples, in order to compare their properties with the ones of plain foam samples. Finally, a component with a complex geometry was manufactured, aiming to evaluate the chance to use the proposed flexible dies as metal foam reinforcements in many instances.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
