ABSTRACT:
A wood composite baseball bat is formed by overlaying a central core of foamed plastic or extruded aluminum with an inner layer of resin-impregnated fiber knitted or woven cloth and then an outer layer consisting of longitudinally extending planks of resin-coated wood veneer. The article is formed by covering the core with the synthetic material impregnated with uncured resin. While the resin impregnating the fibrous material is still unset, the core member is placed within split molds lined with resin-coated strips of wood veneer and the molds are pressed together while the resin is allowed to set to form a unitary mass.
