  • Patent number: 3940466
    Abstract: A method of providing a structural shape includes starting with waste paper and treating the waste paper in a hammer mill to produce paper fibers. The fibers are put through a screen. The screened fibers are mixed with a binder such as a thermosetting epoxy foaming resin or with a phenolic resin in water in preferred proportions. The water or other solvent is kept to a very small value to provide a relatively dry process. The mixture is then pressed in a geometrical shape under substantial pressure (3 to 600 psi). The pressed mixture is then baked or cured at an elevated temperature (175.degree.F to 375.degree.F) for a predetermined time (three minutes to three hours).
