Sandwich materials made of two aluminum sheets and a crumpled aluminum core have been manufactured for the first time using a reproducible process. This very specific core aims to drastically improve the elasticity performance indexes of the sandwich. The structure has been studied mainly in bending.
Key words: sandwich / crumpled / aluminium / stiffness / bending
