FIELD: machine building.
SUBSTANCE: invention can be used for production of metal reinforcing piece intended for installation on front or rear edge of composite blade. Method comprises shaping two metal sheets to approximate a final shape of reinforcing piece that is to be made. Moulded sheets are arranged on both sides of core and tightly connected to each other. Moulded sheets are deformed on core by isostatic pressing in hot state. Deformed sheets are cut for separation of reinforcing piece and release core. At least part of surface of core is given specified roughness, by means of which by isostatic pressing roughness is formed at corresponding part of inner surfaces of reinforcing piece.
EFFECT: avoiding need to implement additional mechanical treatment of surface of reinforcing piece for giving roughness that makes it possible to simplify its manufacture.
