摘要： A method for producing a plastic composite panel which is provided as a layer structure. The method includes providing a film layer structure comprising an adhesive layer which is arranged between two transparent plastic films. The film layer structure is pre-molded to assume an approximately final shape and is arranged in a molding tool so that a first main surface of the film layer structure is towards the molding surface of the molding tool and so that a cavity is formed between the second main surface of the film layer structure and a surface of the molding tool. The film layer structure is then back-molded in a thermal molding method step while introducing a thermoplastic material into the cavity to provide the layer structure. A pre-molding and back-molding step, a rigidification of the thermoplastic layer, and a demolding of the layer structure is further performed.
