A molded, self-supporting, composite part or panel for automotive and similar applications comprises a vapor impervious wood fiber filled polymeric (preferably polypropylene) sheet adhered to one major face of a corrugated paperboard medium and a layer of fibrous insulation (preferably glass fiber) or a second wood fiber filled polymeric sheet adhered to a second major face of the corrugated paperboard medium. The sheet and corrugated medium provide the structural strength for the composite and the fibrous insulation, when used, provides the composite wi...
