VANE MADE OF COMPOSITE MATERIAL COMPRISING A METAL REINFORCEMENT, AND METHOD FOR MANUFACTURING SUCH A VANE

A method for manufacturing a vane made of composite material for a turbomachine, including the steps of three-dimensional fibre weaving and producing a fibrous preform, reinforcing an edge of the preform intended to form a leading edge of a blade of the vane, by integrating a metallic reinforcement...

Beschreibung
Zusammenfassung:	A method for manufacturing a vane made of composite material for a turbomachine, including the steps of three-dimensional fibre weaving and producing a fibrous preform, reinforcing an edge of the preform intended to form a leading edge of a blade of the vane, by integrating a metallic reinforcement on this edge, mounting the preform and the reinforcement in a mould, densifying the preform by a matrix to form the vane, wherein, prior to the integration of the reinforcement, the method includes a step of introducing at least one reinforcement support configured to be interposed between the reinforcement and the edge, and wherein at the densification step, the support is enveloped with the matrix to bond the edge and the reinforcement with a predefined and homogeneous minimum thickness.
