1. A method of repairing a blade made of composite material, extending in an axial direction (X), said blade comprising a blade root and a profiled blade whose axial end opposite the blade root comprises an area to be repaired, said profiled blade comprising an intrados surface and an extrados surface, the method comprising:
a) positioning the blade in a tooling,
b) positioning at least a first foil and at least a second foil, at an apex of the profiled blade to be repaired, respectively on the intrados surface and on the extrados surface of the profiled blade, each foil having an axial end opposite the blade root extending axially beyond the apex of the profiled blade and positioned with respect to a reference of the tooling, said axial end of each foil defining an axial distance between the blade root and an end of the area to be repaired, said foils delimiting between them a refill volume,
c) filling the refill volume with a pasty or fluid refill material, such as a non-polymeric resin such as an unpolymerized resin or a composite refill paste, so that the refill material does not extend beyond the refill volume,
d) curing the refill material by baking or polymerizing said material, and
e) removing the foils.
