Abstract

Préforme fibreuse avec zone cousue d’amortissement des vibrations La présente invention concerne une préforme fibreuse (10) d’aube (1) de turbomachine, comprenant deux portions fibreuses (14) formant un profil aérodynamique de l’aube et définissant entre elles un volume intérieur (16), dans laquelle la préforme fibreuse présente au moins une zone cousue (19) d’amortissement des vibrations dans laquelle les portions fibreuses sont reliées par couture par au moins un fil de couture (190) s’étendant au travers du volume intérieur. Figure pour l’abrégé : Fig. 3.The present invention relates to a fibrous preform (10) for a turbomachine blade (1), comprising two fibrous portions (14) forming an aerodynamic profile of the blade and defining between them a volume interior (16), wherein the fibrous preform has at least one sewn vibration damping area (19) in which the fibrous portions are sewn together by at least one sewing thread (190) extending through the volume interior. Figure for abstract: Fig. 3.
