METHOD OF MAKING A HOCKEY STICK AND STRUCTURE OF SUCH HOCKEY STICK ABSTRACT OF THE DISCLOSURE A method of making a hockey stick comprises the steps of: placing a mandrel of a predetermined length in a bag of a heat-resistant material, with a metal tube being disposed outside the bag and near the open end of the bag; disposing a wooden handle at the outside of the closed end of the bag such that the wooden handle is coaxial with the mandrel; wrapping the bag, the metal tube and the wooden handle with a carbon fiber fabric sheet preimpregnated with epoxy resin; withdrawing the mandrel so that the bag, the metal tube, the wooden handle and the carbon fiber fabric sheet form together a primary stick; arranging the primary stick in a cavity of a molding tool provided with an air tube; closing the molding tool and then heating the molding tool at a temperature slightly higher than a melting point of the epoxy resin before injecting a compressed air under a predetermined pressure into the bag via the air tube of the molding tool; and cooling the molding tool and removing therefrom a freshly made hockey stick.
