Abstract

Procédé de fabrication d’une plateforme inter-aubes avec bords sacrificiels L’invention concerne un procédé de fabrication d’une plateforme inter-aubes d’une soufflante de turbomachine, ladite plateforme comprenant un corps ainsi qu’un premier et un deuxième bords latéraux sacrificiels, le procédé étant caractérisé en ce qu’il comprend : - la fourniture de préformes fibreuses du premier bord sacrificiel et du deuxième bord sacrificiel (251, 252), - la réalisation d’une préforme fibreuse du corps (210) de la plateforme en une seule pièce par tissage tridimensionnel, - la disposition des préformes fibreuses (251, 252, 210) dans un moule d’injection (70), les préformes des premier et deuxième bords sacrificiels (251, 252) étant disposées de part et d’autre de la préforme fibreuse du corps (210), - la densification des préformes fibreuses (251, 252, 210) disposées dans le moule (70) par une matrice pour former une unique pièce ayant la forme de la plateforme à fabriquer.
