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.
Claims25
A ball bat having a bulbous end portion tapering to a narrow handle portion comprising:
- a substantially rigid, elongated central core, extending substantially the full length of the bat;
- an inner tube of fibrous reinforcement fabric impreganted with resin, surrounding the core;
- and
- an outer tube formed of a sheet of wood veneer, said sheet comprising an elongated strip having its length substantially parallel to the longitudinal axis of the bat, said sheet being coated and impregnated with resin, and surrounding said inner tube and adhered thereto by said resin.
A ball bat having a bulbous end portion tapering to a narrow handle portion, comprising:
- a substantially rigid, elongated central core, extending substantially the full length of the bat;
- a first tubular layer of fibrous reinforcement fabric overlying the core;
- a second tubular layer of wood veneer overlying the fibrous reinforcement fabric, said wood veneer comprising an elongated strip having its length substantially parallel to the longitudinal axis of the bat;
- the first and second layers being impregnated with and adhered to one another and to the outer surface of the core by synthetic resin so as to form a unitary structure.
A ball bat having a bulbous end portion tapering to a narrow handle portion comprising an elongated tube of fibrous reinforcing fabric and a tube formed of a sheet of wood veneer, said sheet comprising an elongated strip having its length substantially parallel to the longitudinal axis of the bat, the sheet surrounding and encasing the fibrous reinforcing fabric tube, the fabric tube and the wood veneer sheet each being impregnated with and adhered to one another by resin.
