HIGH PRESSURE VESSEL FOR HOME USE UTILIZING DEEP DRAWING AND MANUFACTURING METHOD

PURPOSE: A high pressure vessel for home use using deep drawing, and a manufacturing method thereof are provided to increase the strength of a liner body by winding a fiber filament wire on the liner body. CONSTITUTION: A high pressure vessel for home use using deep drawing comprises an aluminum liner body(10), a fiber filament wire(20), and an epoxy resin layer(30). The aluminum liner body comprises a bottom part, a cylindrical part, and a top part. A circular plate is deep-drawn by a punch and a die to form the bottom part. The bottom part is a cup shape. The cylinder part is formed above the bottom part. The upper side of the cylindrical part is spun to form the cup-shaped top part. The top part has a screw part to which a regulator is coupled. The fiber filament wire is formed of a carbon fiber or a glass fiber, and is wound on the outer surface of the aluminum liner body. The epoxy resin layer is thermally cured on the outer surface of the fiber filament wire.
