A flat composite panel (10) having an elastoplastically deformable core (12) and at least one covering layer (14, 16) of a plastically or thermoplastically deformable material, arranged on one side, is bent in a simple, cost saving way. At least one covering layer (14, 16) and the underlying core material of the composite panel (10) are notched stepwise in a straight line on the bending inner side, notches (22) of two opposite covering layers (14, 16) being offset in the longitudinal direction. As apparatus, a framework having an embossing roll or a press with an exchangeable pressing tool (18) in the form of a bar or sheet is used. The bent composite panels have a wide range of applications, in particular in architecture or in vehicle construction.
