Abstract

A use of a coilable multi-layer metallic composite material produced by means of roll-cladding in a vehicle structure, in particular a body structure, provides an alternative to monolithic materials. The composite material used in a vehicle structure is a lightweight composite material and comprises three layers of a steel alloy, wherein at least one of the layers is formed from a high-strength or very high-strength steel alloy.
