摘要:
A method for manufacturing a vane from a composite material with a fitted metal leading edge includes the successive draping, on a template of the leading edge of the vane to be manufactured, of a first layer of a base material and of a second layer of an adhesive material, the transfer of the first and second draped layers in the recess of a metal foil, the positioning of the foil including the first and second draped layers alongside the leading edge of a vane preform including a fiber reinforcement impregnated with a precursor of a matrix, the co-curing of the vane preform and of the first and second draped layers so as to obtain a vane made of composite material including on its leading edge a bonded metal foil.
