Abstract
A composite vane for a low-pressure compressor of an axial-flow turbomachine, wherein the vane comprises a platform and an aerodynamic airfoil having a leading edge and a trailing edge. The airfoil extends into the primary flow of the turbomachine. The airfoil includes a body extending from the leading edge to the trailing edge and a reinforcement of the leading edge of the airfoil. The reinforcement comprises a reinforcing sheet, which extends from the leading edge to the trailing edge, and which is arranged in the thickness of the body in such a way as to reinforce it. In addition, the reinforcement comprises a shell forming the leading edge and which is integral with the sheet. The sheet is a titanium sheet, and the body includes a composite material having an organic matrix charged with fibers. This configuration improves the rigidity and the resistance to corrosion while lightening the airfoil.
