Abstract: A method for manufacturing a straight insert intended to be incorporated in a metal container by HIC includes placing coated wires in a rectilinear juxtaposition over a predefined length in a straight gutter-shaped tool and joining the coated wires together. The insert includes a bundle of coated wires that are joined together and have a predefined length. The wires are made from metal-coated ceramic fibers.

Abstract: A method of manufacturing an elongate insert configured to be integrated by CIC in a metal container, including coated yarns bonded together, the coated yarns being formed from metal-coated ceramic fibers. The method includes placing the coated yarns side by side in a bundle and pulling the fiber bundle through a shaping element so as to compact the fiber bundle transversely while forming the fiber bundle so as to have a defined cross section. A metal part incorporating a fibrous insert can be manufactured by the CIC technique.

Abstract: The invention relates to a process for manufacturing a tubular part, which includes an insert made of a metal matrix composite and within which ceramic fibers extend. The process comprises the following steps: the filaments of a filament bundle are fixed close to one end of a support part, said filaments being separate from one another and each filament comprising a ceramic fiber coated with a metal sheath; and all the filaments of the bundle are wound around the support part along a helical path.

Abstract: A process for manufacturing a coiled insert of coated filaments is disclosed. Each filament includes a ceramic fiber coated with a metal sheath. The process includes a step of winding a sheet of coated filaments around a piece. At the start of winding, a first metal shim is placed beneath the sheet and coiled. At the end of winding, a second metal shim is placed on the sheet and coiled. The process is applied to the manufacture of aeronautical turbomachine components.

Abstract: The invention relates to a data transmission electric wire comprising a plurality of conductor strands covered in at least one insulating covering including PTFE, the plurality of strands comprising an inner core of first strands covered by at least one outer layer of second strands, said first and second strands being constituted of different metals, the metal of said second conductor strands presenting hardness that is lower than that of the metal of said first conductors, and said first strands being constituted essentially by an alloy of copper and said second strands being constituted essentially of copper. According to the invention, said alloy is a homogeneous copper alloy in the alpha phase that is stable at a temperature less than or equal to 500° C.

Abstract: Process for manufacturing a coiled insert of coated filaments, each filament comprising a ceramic fiber coated with a metal sheath, characterized in that it includes a step of winding a sheet of coated filaments onto a piece, in which step, at the start of winding, a metal shim for catching the internal part of the insert is coiled and, at the end of winding, a metal shim for catching the external part of the insert is coiled. The process is applied to the manufacture of aeronautical turbomachine components.

Abstract: Aluminum cable type electrical conductor having at least one stranded conductor based on conductive wires with an aluminum core coated with an intermediate layer of copper itself coated by a surface layer of nickel. The surface layer of nickel has a thickness from about 1.3 ?m to about 3 ?m, it has sufficient continuity to resist a polysulfide bath continuity test for at least 30 seconds without visible traces of attack of the copper appearing at ×1O magnification. This kind of conductor is particularly suitable in small diameters for conducting electricity in aircraft and motor vehicles.
