Abstract
A composite plate contains a core layer with a honeycomb structure between two cover layers, the first cover layer of which carries a decorative panel and the second cover layer of which carries a rear protective plate. The adhesive bonds of the composite plate consist of a layer of a relatively nonflammable adhesive. The protective element, made of a silicate base (but without asbestos) or a non-combustible mineral substance base, is adhesively bonded to the rear side of the composite plate.
