Procédé de fabrication amelioré d'une pièce à geometrie tubulaire en matériau composite à matrice céramique
The device (100) has a preform assembly element (3) arranged at an end of a longitudinal main body (2), and another preform assembly element (4) mounted on a control rod (5) at another end of the main body by a helical link. Coaxial elements co-act with each other when ends of a preform are held on the assembly elements such that rotation of the control rod about its axis causes translation of the latter assembly element about the axis. The assembly elements are separated from each other along the axis to tension the preform along longitudinal direction (A). An independent claim is also included for a method for manufacturing a hollow part.
