  • Publication number: 20240018640
    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.

  • Patent number: 11435279
    Abstract: A method for analysing a bonding between two aeronautical parts. The method includes the steps of a) applying a release agent to a first surface to be bonded of a first part and to a second surface to be bonded of a second part, b) applying an adhesive to at least one of the first and second surfaces and positioning these surfaces on top of each other, the adhesive forming an adhesive film after polymerisation, c) separating the parts from each other and removing the adhesive film in one piece, d) analysing the adhesive film. The invention also relates to a method for bonding two aeronautical parts.

  • Publication number: 20220266584
    Abstract: A method of adhesively bonding a first substrate on a second substrate in an adhesive bonding zone by an adhesive joint integrating a support mesh, wherein surplus adhesive joint is folded over onto one or the other of the first or second substrates so that the support mesh is present over the entire adhesively bonded zone after curing.

  • Publication number: 20220134679
    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.

  • Patent number: 11254067
    Abstract: A method for producing a part. This part including a surface portion whereon is positioned an element to be assembled via an adhesive on the surface portion. The method includes the steps of: mounting a sleeve of heat-shrinkable material around at least one portion of the element on the part, heating of the sleeve in order to shrink it and thus to apply an application force of the element on the surface portion, hardening of the adhesive, and removing the sleeve.

  • Patent number: 10794818
    Abstract: A peel testing device designed to test the resistance to peeling of test pieces each formed from a support and from a reinforcement glued to this support, and comprising a frame with a face roller and at least one guide roller, a traction machine configured to peel the reinforcement from the surface of the support in a peeling direction tangential to the face roller and a sensor for measuring the force exerted by the traction machine during peeling, the device also comprising a fastening cable connected, on the one hand, to the traction machine and on the other hand to the face roller with which it forms a pulley system and the face roller which has a greater diameter than that of the guide roller comprises a mounting element for holding the reinforcement fixedly there.

  • Publication number: 20190039339
    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.
