Abstract

A method is provided for producing a composite part, in particular a flat composite part, having a foam core that has a first and second cover layer which are bonded to the foam core on a first surface and a second surface, respectively. The method has the following steps: (a) heating the cover layers and the foam core (b) positioning the cover layers on the surfaces of the foam core, (c) positioning the foam core and the cover layers in a press or a mold which forms the completed composite part, (d) reshaping the foam core and the cover layers in the press or in the mold, wherein the cover layers can be positioned on the surfaces of the foam core, (e) cooling and bonding the cover layers and the foam core in the press or in the mold, and (f) removing the composite part from the press or from the mold.
