Zusammenfassung:	The invention relates to a method for manufacturing a vane (100) made of composite material for a turbine engine, comprising the steps of: - three-dimensionally weaving fibres and producing a fibrous preform (100'), - reinforcing an edge (108') of the preform (100') intended to form a leading edge of a blade of the vane, by integrating a metal reinforcement (130) onto this edge (108'), - mounting the preform (100') and the reinforcement (130) in a mould, - densifying the preform (100') with a matrix in order to form the vane (100), wherein, before integration of the reinforcement (130), the method comprises a step of introducing at least one reinforcement support (140) designed to be inserted between the reinforcement (130) and the edge (108') and wherein, in the densification step, the support (140) is surrounded by the matrix in order to adhesively bond the edge (108') and the reinforcement (130) with a predefined, minimal and homogeneous thickness. L'invention concerne un procédé de fabrication d'une aube (100) en matériau composite pour une turbomachine, comprenant les étapes de : - tissage de fibres en tridimensionnel et réaliser une préforme fibreuse (100'), - renfort d'un bord (108') de la préforme (100') destiné à former un bord d'attaque d'une pale de l'aube, par intégration d'un renfort métallique (130) sur ce bord (108'), - montage de la préforme (100') et du renfort (130) dans un moule, - densification de la préforme (100') par une matrice pour former l'aube (100), dans lequel, avant l'intégration du renfort (130), le procédé comprend une étape d'introduction d'au moins un support de renfort (140) configuré pour être intercalé entre le renfort (130) et le bord (108'), et dans lequel à l'étape de densification, le support (140) est enveloppé de la matrice pour coller le bord (108') et le renfort (130) avec une épaisseur minimale prédéfinie et homogène.
