The invention relates to a multilayer composite material for the production of plastics moldings, to a container made of this composite material, and also to a process for the production of the container. The composite material comprises a first structure-providing self-supporting rigid external layer made of a fiber composite material, a second structure-providing external layer, a first intermediate layer made of a barrier plastic and a second cracking-resistant intermediate layer made of a thin cracking-resistant film, and also at least one adhesion promoter layer, where the intermediate layers and the adhesion promoter layer have been embedded between the structure-providing external layers and form an adhesion bond with the structure-forming external layers, and where the thickness of each of the structure-providing external layers is many times the thickness of each of the intermediate layers or of the adhesion promoter layer.
