Abstract
A hockey stick formed having a double-box beam shaft defining an elongated handle, and a molded laminated blade structure integrally molded to one end of the double-box beam shaft. The laminated blade is formed by molding a plastic core having laminated therein outer oppositely disposed preformed resin-impregnated web-like cloth sheets, and inner oppositely disposed unidirectional fiberglass-strip members positioned longitudinal of the main-body portion of the blade, the fiberglass strips being held in spaced relationship to each other by foam spacers, whereby a pair of elongated fiberglass rod members are interposed between a portion of the strips and the angularly disposed neck portion of the blade, and encapsulated within the plastic core, the rods extending outwardly to be integrally molded to the shaft.
