Abstract
Abstract A veneer laminate composite structure particularly suitable for use in boat building. The structure comprises a first sheet of wood veneer having its grain extending generally in the plane of the sheet; a second sheet of wood veneer juxtaposed to the first sheet and having its grain extending generally in the plane of the sheet but generally at cross angles with respect to the grain of the first sheet of wood veneer; a resin interposed between and bonding the wood veneer sheets together; a first sheet of fiberglass juxtaposed to the second sheet of wood veneer; further resin interposed between and bonding the second sheet of wood veneer and the first sheet of fiberglass; a sheet of end core balsa wood juxtaposed to the first sheet of fiberglass; further resin interposed between and bonding the sheet of end core balsa wood and the first sheet of fiberglass; a second sheet of fiberglass juxtaposed to the sheet of end core balsa wood; and further resin interposed between and bonding the sheet of end core balsa wood to the second sheet of fiberglass.
