Vane made of composite material comprising a metallic reinforcement and method for manufacturing such a vane

A method for manufacturing a vane made of composite material for a turbomachine, said vane comprising a blade having an intrados face and an extrados face extending between a leading edge and a trailing edge, the method comprising the steps of:

• weaving fibres in three dimensions so as to produce a fibrous preform,
• reinforcing an edge of said fibrous preform intended to form the leading edge of the blade, by integrating a metallic reinforcement on said edge of the fibrous preform,
• assembling the fibrous preform and the metallic reinforcement in a mould,
• densifying the fibrous preform by a matrix to form the vane made of composite material,
• wherein, before the reinforcing step, the method comprises a step of introducing at least one reinforcement support onto the edge of the fibrous preform, said reinforcement support being configured so as to be interposed between the metallic reinforcement and said edge of the fibrous preform, and in that, in the densification step, said reinforcement support is enveloped with the matrix to bond the edge of the fibrous preform and the metallic reinforcement with a predefined and homogeneous minimum thickness,
• wherein the edge of the fibrous preform comprises an intrados wall and an extrados wall connected together by a ridge, said reinforcement support covers at least a portion of said intrados and extrados walls up to a ridge of the edge of the fibrous preform, and
• wherein the reinforcement support is not covering the ridge of the edge of the fibrous preform.
