MOULDING A HOLLOW GOLF CLUB SHAFT FROM COMPOSITE FIBRE/RESIN MATERIAL

摘要

The invention relates to a method for fabricating a golf club shaft in composite materials. The method is comprised particularly of the following successive steps: a sealed elastic tubular bladder (8) is arranged around a rigid mandrel (9) whose length is at least equal to the length of the shaft to be made; the mandrel is then covered with a composite structure (11) including fibers impregnated with a synthetic resin matrix; the mandrel (9) is arranged in the mold (12); a molding is then operated by applying at least one internal pressure exerted by introducing a fluid inside the bladder (8). The invention also relates to the device as well as to shafts made according to said method.
