Tubular golf club shaft made from composite materials comprising layers of fibers impregnated with plastic resin and provided over its length with at least one are of enlargement (,) and or narrowing. The curve of generation of the internal diameter of the shaft as a function of its length beginning at the point of the smallest internal diameter and extending to at least one of the ends of the shaft incorporates at least one decreasing portion.

Golf club shaft

Process of manufacturing a golf club shaft made of composite materials, including the successive steps of fitting a tubular, flexible impermeable bladder around a rigid mandrel, dressing the mandrel with a composite structure including fibers impregnated with a synthetic resin matrix, placing the mandrel in the mold, and then carrying out a molding operation by applying at least one internal pressure exerted by feeding a fluid inside the bladder.
