Abstract

L'objet de l'invention est un mandrin pour réalisation de pièces composites par bobinage filamentaire, qui comporte un noyau central solide réalisé en une ou plusieurs parties (11, 12, 13) et un fil, tube, corde ou câble bobiné à spires jointives sur la contre-forme et formant un bobinage superficiel sur ledit mandrin. Avantageusement, le bobinage superficiel est lui-même recouvert d'un film de finition. FIGURE 3
