Formable composite panel having a plurality of layers with at least one outer layer of an aluminium alloy and a core layer out of plastic. The core layer is 20 to 150 æm thick and each outer layer of aluminium alloy is 400 to 1600 æm thick and each layer of aluminium alloy is of a formable aluminium alloy of the type AA 1xxx (pure Al), AA 3xxx (AlMn), AA 5xxx (AlMg), AA 6xxx (AlMgSi), AA 7xxx (AlZnMg) or AlFeSi. Preferred composite panels feature a core e.g. of acrylic viscoelastic polymers and on both sides of the core outer layers of the above mentioned aluminium alloys. The composite panels may for example find application as car body sheet in the production of the bodies of road bound vehicles such as private cars.
