  • Patent number: 5496648
    Abstract: The present invention relates to multilayer wood veneer composite laminates, the outermost layer of which is a natural wood veneer, and the substrate of which is a plurality of layers of cellulose-containing plastic sheets, and a method to make the composite laminate. The composite laminate according to the present has the look, feel, heft, and sound when struck of natural wood. The method has a very short cycle time, which increases the utilization of capital equipment, and includes the steps of laying-up the substrate layers, pre-heating the substrate layers, applying adhesive to the bottom surface of the outer layer or layers, laying-up the outer layer(s) on the pre-heated substrate layers, and cold pressing the layers in a compression die. The laminate is then de-molded. If a metal die is utilized, the laminate will be cool upon de-molding.
