A method for fabrication of a bent reinforcing rod in a composite material is described, where the reinforcing rod is composed of longitudinal fibres and a sheathing layer of fibres or foil, comprising the steps: to moisten fibre thread with a binding agent, to reel the moistened fibre thread to a bundle with a closed, approximately circular shape, consisting of a layer of longitudinal, parallel fibres of a desired thickness, whereby all the fibres in the layer obtain an approximately equal axial tightening, and to envelope an outer layer of fibre threads, and/or foil, or other suitable material, around the layer of longitudinal fibres, and that the fabricated blank is given a final form in a second forming process. The invention also relates to a device (10) for carrying out the method.

L'invention concerne un procédé de fabrication d'une barre d'armature courbée en matériau composite, ladite barre étant constituée de fibres longitudinales et d'une couche de revêtement de fibres ou de type feuille. Le procédé comporte les étapes consistant à : mouiller le fil de fibres à l'aide d'un liant ; bobiner ledit fil mouillé en botte de manière à produire une forme fermée approximativement circulaire et constituée d'une couche de fibres parallèles longitudinales d'épaisseur voulue, toutes les fibres de la couche présentant un serrage axial approximativement égal ; et envelopper d'une couche extérieure de fils de fibres et/ou d'une feuille ou de toute autre matière adéquate, la couche de fibres longitudinales. La forme finale de l'ébauche fabriquée est obtenue au cours d'un deuxième processus de formage. L'invention concerne aussi un dispositif (10) permettant de mettre en oeuvre le procédé.
