Abstract: The invention relates to a method for manufacturing a composite material (8) comprising a metal matrix reinforced by a carbon reinforcement, characterised in that the method is a continuous extrusion method which comprises friction-heating of a mixture (7) obtained from a mixture of powders comprising a metal-matrix powder and a carbon-reinforcement powder, by means of a movable extrusion wheel (2), in a passage formed between a groove (2a) of the wheel (2) and a stationary element referred to as shoe (3), followed by carrying the mixture (7) thus heated towards an extrusion die (4).

Abstract: The invention relates to an electric power transmission cable comprising at least one central composite core (1A, 1B) formed of fibers embedded in a resin and around which metal conductive wires (2, 3) are positioned, said core (1) being coated with a coating layer (4) consisting of carbon nanotubes embedded in a resin. According to the invention, said coating layer consists of only 4% to 8% by weight of carbon nanotubes embedded in said resin.

Abstract: The invention relates to an electrical cable (1, 10) comprising at least two conducting strands (2, 3) and theft deterrence means in the form of a marking (8). The main characteristic of an electrical cable (1, 10) according to the invention is that the marking consists of a series of relief prints (8) akin to a bar code.

Abstract: The present invention relates to an electrical control cable of the type comprising a core having a plurality of polymer filaments, a plurality of strands of conductor material extending in the longitudinal direction of said core, an outer insulating sheath. According to the invention, said strands are distributed uniformly and concentrically over the periphery of said core, in contact with one another in pairs and in contact with said core, and the filaments of said core are secured to one another to form a non-metallic unitary structure that is obtained by organizing said filaments into a plurality of subassemblies, the filaments in any one subassembly being twisted together helically, the subassemblies in turn being twisted with one another to form an overall helix. Advantage: the cable uses a limited number of copper strands while guaranteeing that crimping operations are reliable.

Abstract: A composite control cable has a polymer core and a plurality of strands of electrically conductive material extending in the longitudinal direction of the cable around said core. The polymer is selected from polymers presenting elongation at break that is greater than 7%, and traction strength such that the resultant traction strength of the cable is greater than a predetermined limit value.

Abstract: The present invention relates to an electric control cable of the type comprising a core of polymer material and a plurality of copper strands extending in the longitudinal direction of said core, said copper strands being distributed uniformly and concentrically on the periphery of said core so as to penetrate only partially into said core, with each of them leaving a portion that is accessible from outside said periphery. According to the invention, said copper strands are embedded in part in the material forming the core and extend parallel to the longitudinal direction of said core. Advantage: fabrication is simplified and copper is saved, while still enabling easy access to the copper for subsequent crimping of the cable for connection purposes.

Abstract: An electrical cable with a section diameter at most equal to 2 mm includes a plurality of strands extending in the longitudinal direction of the cable. The strands are twisted to form a stranded conductor. Only certain strands of the stranded conductor are of electrically conductive material, for example copper, the remaining strands are of non-conductive material, such as polyamide, high strength polyester or a polyetherimide.
