  • Method of making self-supporting composite structures
    Patent number: 5766395
    Abstract: 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 with good sound absorption properties. The wood fiber filled polymeric sheet is formed during the molding process from a wood and polymeric fiber sheet. The heat and pressure of the molding process cause the polymeric fibers to melt and flow about the wood fibers to form the wood fiber filled sheet and bond the sheet securely to the corrugated medium.
