  • Patent number: 4153490
    Abstract: A composite article is obtained by forming a body of a mixture of a fibrous material with a heat-hardening binder, by interposing between the body and a coating layer an intermediate layer having a tear-resistance and stiffness exceeding those of the coating material and impregnated with a resin which softens more slowly than a different resin with which the coating layer is impregnated, and by transforming the assembly of the body with the layers into the final article. During the transformation, the assembly is heated to a temperature at which the binder of the body hardens, and the resin of the intermediate layer softens more slowly than that of the coating layer. The intermediate layer may include asbestos fibers, or it may be a metallic foil or a soda craft paper.
