Abstract: A device for confining a given zone of a part. The device having a first rigid sleeve open to a first end which is capable of being applied around said given zone of the part. The device further having a second flexible and elastic sleeve open to a same first end as the first sleeve and intended to be applied on the part. The second sleeve remotely surrounds the first rigid sleeve so as to form an annular space which is connected to the means for depressing the annular space.

Abstract: A method for treating the surface of a titanium or titanium alloy metal reinforcement of a blade made of composite material enables selective removal of a bonding primer with respect to the titanium or titanium alloy reinforcement. The method includes subjecting the metallic reinforcement to a thermal treatment performed at a temperature of between 250 and 350° C. for a period of between 1 hour and 10 hours in an oxidizing atmosphere. The method further includes subjecting the metallic reinforcement, after the thermal treatment, to a chemical pickling in an alkaline bath.

Abstract: A method for assembling a body and a cover of a vane by polymerisation of a resin. The covens positioned on a junction face of the body covered with this resin. A sheet is placed against a pressure side of the vane, formed by an outer face of the cover and an outer face of the body, so as to define a space sealed with a bead of mastic sealant. The bead of mastic sealant is deposited on the outer face of the body, around the junction face of this body. The space between the sheet and the pressure side of the vane is placed under vacuum during a heating operation of the vane in an autoclave, in order to press the cover against the body of the vane.
