Title (EN) METHOD FOR MANUFACTURING A TURBINE ENGINE VANE
(FR) PROCEDE DE FABRICATION D'UNE AUBE DE TURBOMACHINE
Abstract:
(EN) The invention relates to the manufacture of a vane by 3D weaving a preform to be impregnated with resin. According to the invention, the visibility of the cut ends of some yarns of the preform (16) is accentuated, for example the warp yarns, to reveal curved lines (20), and the configuration of said curved lines is compared with a reference configuration to ensure correct the shaping of the preform.
(FR) Fabrication d'une aube par tissage 3D d'une préforme destinée à être imprégnée de résine. Selon l'invention on accentue la visibilité des extrémités coupées de certains fils de la préforme (16), par exemple les fils de chaîne pour faire apparaître des lignes courbes (20) et on compare la configuration de ces lignes courbes avec une configuration de référence pour une bonne conformation de la préforme.
