Title (EN) METHOD FOR FABRICATING GOLF CLUB SHAFTS
(FR) PROCEDE DE FABRICATION DE MANCHES DE CLUB DE GOLF
Abstract:
(EN) 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.
(FR) L'invention concerne un procédé de fabrication d'un manche de club de golf en matériaux composites. Le procédé comprend notamment les étapes successives suivantes: on dispose une vessie tubulaire (8), élastique et étanche autour d'un mandrin rigide (9), de longueur au moins égale à la longueur du manche à réaliser; on réalise ensuite l'habillage du mandrin avec une structure composite (11) comprenant des fibres imprégnées d'une matrice de résine synthétique; on dispose le mandrin (9) dans le moule (12); on effectue ensuite une opération de moulage en appliquant au moins une pression interne exercée par l'introduction d'un fluide à l'intérieur de la vessie (8). L'invention concerne également le dispositif ainsi que les manches réalisés selon le procédé.
