Abstract
A method of making golf clubs of thermoplastic composite material is disclosed. The present method is characterized in that the composite material wound around a mandrel is consolidated by using a metal sheet. This method comprises the steps of: (a) providing a tapered mandrel, and wrapping the mandrel with at least a sheet of thermoplastic prepreg to form a laminated outer shell; (b) heating the thermoplastic prepreg to a molten state; (c) enclosing the laminated outer shell with at least a metal sheet, and heating the metal sheet and the laminated outer shell while constricting said metal sheet to thereby consolidate the molten prepreg to form a tubular body; and (d) releasing the metal sheet and withdrawing the mandrel from the tubular body.
