Abstract: A method for manufacturing a connection and/or transmission mechanical part disposed between two structures, which consists in carrying out the following successive operations:

making a rigid framework, through operations of shaping at least one rod or the like, in order to replicate the volume shapes of the part and create, at determined locations, segments with shapes suited to optimise the strength and the rigidity of the part,
incorporating into the framework at least one element suited to make an interface of the part with either one of the structures,
moulding a plastic matrix around the framework.

Abstract: The invention relates to a sacrificial composite part (1, 10, 100) that absorbs the energy released at the time of a vehicle collision with an impacting object (2), said part consisting of an assembly of a plurality of cells (3, 30, 300), each cell comprising a wall (5, 50, 500) connecting a first end (6, 60, 600) and a second end (7, 70, 700) of said cell, the direction of penetration (8) of the impacting object into said part going from said first end to said second end. Said sacrificial composite part of the invention is characterized in that that peripheral wall of each cell has a decreasing thickness (e) from said first end towards said second end of said cell, in the direction of penetration of the impacting object.

Abstract: Composite-structure rotor for axial flow electrical machines comprising at least one stator and a rotor rigidly connected to a shaft to be rotated, in the shape of a disc and comprising a plurality of permanent magnets supported by a support made of a composite material rigidly connected to the shaft to be driven and constituted by a reinforced fibre matrix, The rotor comprises distributed attachment means for the radial elements and segments, which connect the elements in pairs, forming recesses, and which comprise at least one strap resulting from the winding of continuous unidirectional fibres passing between th Composite-structure rotor for axial flow electrical machines comprising at least one stator and a rotor rigidly connected to a shaft to be rotated, in the shape of a disc and comprising a plurality of permanent magnets supported by a support made of a composite material rigidly connected to the shaft to be driven and constituted by a reinforced fibre matrix. The rotor comprises distributed attachment means for the radial elements and segments, which connect the elements in pairs, forming recesses, and which comprise at least one strap resulting from the winding of continuous unidirectional fibres passing between the magnets, on the outside edge thereof, as well as on each of the attachment means, in order to form a collective retention of the magnets.
