Abstract
A composite sheet comprising two sheets joined by material closure provides on the one hand high global and local bending stiffness, and on the other hand very good forming behavior and very high load capacity in case of great deformations, as in case of a crash for example. Both sheets of the composite sheet comprise an at least partially structured surface and a smooth surface and both sheets are at least partially joined by material closure via the structured surfaces.
