A method of making a golf club includes the use of an inner tube, which is made of an elastic and refractory material and is wrapped orderly onto with at least a matrix layer of thermoplastic material and with at least a reinforcing layer of long fiber material so as to form a tubular body having a laminated outer shell. The tubular body is heated in a molding tool up to a temperature corresponding to the melting point of the thermoplastic plastic material. A pressurized gas is introduced into the tubular body to force the molten thermoplastic plastic material to diffuse evenly into the interstices of fiber bundles making up the long fiber material. After being cooled, the molding tool is opened to remove therefrom the golf club made of plastic composite material. Such golf club is tough, light in weight, and has an excellent shock-absorbing quality.
