Abstract

L’invention concerne une préforme d’aube composite (10) présentant un tissage tridimensionnel entre des fils de chaîne et des fils de trame. La préforme comprend une zone de préforme conformée (Z0) qui s'étend sur une hauteur Hz0 comprise entre 60% et 90% de la dimension longitudinale H du corps de la préforme et sur une largeur lz0 correspondant à la dimension transversale C de la préforme, la zone (Z0) comportant une bande de conformation (b0) qui s’étend sur la hauteur Hz0 et sur une largeur lb0 inférieure à lz0 et qui est positionnée transversalement à une distance d’un premier bord (12) de la préforme située entre 40 et 50% de la dimension transversale C, l'angle de décadrage entre le ou les fils de chaîne et de trame dans la bande (b0) étant minimal par rapport à celui entre les fils de chaîne et de trame en dehors de la bande. Figure pour l’abrégé : Fig.1A composite blade preform (10) having a three-dimensional weave between warp yarns and weft yarns. The preform comprises a shaped preform zone (Z0) which extends over a height Hz0 of between 60% and 90% of the longitudinal dimension H of the body of the preform and over a width lz0 corresponding to the transverse dimension C of the preform , the zone (Z0) comprising a conforming band (b0) which extends over the height Hz0 and over a width lb0 less than lz0 and which is positioned transversely at a distance from a first edge (12) of the preform located between 40 and 50% of the transverse dimension C, the offset angle between the warp and weft yarn(s) in the band (b0) being minimal compared to that between the warp and weft yarns outside the band band. Figure for abstract: Fig.1
