Beschreibung
Zusammenfassung:	The invention relates to a guide vane (10) made from composite material for a gas turbine engine, comprising a fibrous reinforcement densified by a matrix, the fibrous reinforcement being formed as a single component by means of three-dimensional weaving with a blading (12) and at least two attachment flanges (14a, 14b, 24a, 24b, 26a) extending from a radial end (16, 18) of the vane towards opposing side faces (12a, 12b) of the blading, said attachment flanges being axially staggered in relation to each other. The invention also relates to a method for producing such a vane. L'invention concerne une aube de redresseur (10) en matériau composite pour moteur à turbine à gaz comprenant un renfort fibreux densifié par une matrice, le renfort fibreux étant formé en une seule pièce par tissage tridimensionnel avec un aubage (12) et au moins deux brides de fixation (14a, 14b, 24a, 24b, 26a) s'étendant depuis une extrémité radiale (16, 18) de l'aube vers des faces latérales (12a, 12b) opposées de l'aubage, lesdites brides de fixation étant décalées axialement l'une de l'autre. L'invention concerne aussi un procédé de fabrication d'une telle aube.
