Zusammenfassung:	A method for producing a tubular fiber arrangement of a fiber-reinforced composite part and a tubular fiber arrangement as an intermediate product for a composite part. The local conditions are taken into account with respect to the geometry of the composite part and its load profile. When forming the composite part on a core, the fiber mass supplied during the formation of the tube is proportional to the local circumference of the composite part which results from the diameter. The advancement speed of the core remains substantially constant. L'invention vise à mettre en oeuvre un procédé de fabrication d'un dispositif à fibres en forme de flexible d'un élément composite renforcé par fibres (3, 11, 13) et un dispositif à fibres en forme de flexible, en tant que produit intermédiaire pour un élément composite (3, 11, 13), les conditions locales en termes de géométrie de l'élément composite (3, 11, 13) et son profil de contrainte étant pris en compte de façon particulièrement simple et fiable. A cet effet, lors de la formation de l'élément composite sur un noyau, la matière de fibres (6, 4a, 4b, 4c, 12) introduite lors de la fabrication du flexible présente un comportement proportionnel par rapport à la périphérie locale de l'élément composite (3, 11, 13), obtenue à partir du diamètre, la vitesse d'avancement du noyau restant sensiblement constante.
