The method of the present invention comprises inserting a moldable slug having a plurality of longitudinally oriented resin impregnated predominantly glass fiber filaments into a bow limb profiling mold. The mold consists of two halves, the first half containing two female cavities and a second half having two matching fitted male sections. Each cavity receives a predetermined volume and weight of continuous longitudinal fibrous reinforcement material and plastic resin matrix material. Heat and pressure are applied during initial curing and the uncured end is removed. The slug is then finally cured.

Cette invention concerne une méthode d'insertion d'une ébauche moulable composée de fibres principalement de verre orientées longitudinalement et imprégnées de résine dans un moule de profilage de branches d'arc. Le moule est en deux coquilles, la première comportant deux empreintes en creux et la seconde, deux sections en relief de même contour. Chaque empreinte reçoit une masse volumique prédéterminée de fibres continues longitudinaux de renfort et un matériau matrice en résine plastique. De la chaleur et de la pression sont appliquées durant la cuisson initiale et le bout non cuit est enlevé avant traitement de cuisson final du produit moulé.
