  • Patent number: 10710749
    Abstract: A device and a method of assembly by brazing or diffusion-welding under a gaseous pressure is provided to make structures for a nacelle of an aircraft turbojet engine such as an inner fixed structure. Sealing of the assembly space inside which the parts to assemble are disposed is provided by tie members exerting a mechanical pressure on mold elements. The tie members include jaws made of a first material and a holding element made of a second material. The first material has a thermal expansion coefficient higher than that of the second material.

  • Patent number: 10513067
    Abstract: An assembly includes a first part made of composite material including a polymer matrix and a second part made of metal. The two parts are assembled by opposite or assembly faces along an interface subjected to shear loads. The first part is made of a composite having continuous reinforcing fibers in a thermoplastic matrix. The second part includes, on its assembly face, a coupling form having a plurality of patterns. Each pattern has a closed contour in a plane parallel to the assembly face of the second part and extends along a direction normal to the assembly face of the second part. A method for making such an assembly is also provided.
