Abstract: Arbre de torsion composite (41) permettant de raccorder un moteur à fluide de fond (20) au trépan (30) se trouvant à l'extrémité d'un train de tiges de forage. L'arbre de torsion composite comprend un corps matriciel allongé dans lequel sont fixées des fibres orientées. Les fibres sont orientées de manière à donner à l'arbre de torsion composite (41) une résistance à la torsion et une rigidité élevées tout en permettant une certaine souplesse de flexion. Ainsi, l'arbre de torsion composite transforme le mouvement giratoire et rotatif du rotor dans le moteur à fluide en pure rotation du trépan.
