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.

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: A run flat device intended to be mounted in a tyre around a wheel rim of a vehicle, the device comprising at least one assembly of two half-shells assembled axially, each half-shell being made of a composite material based on fibres embedded in a thermoplastic or thermosetting resin, each half-shell comprising a radially internal periphery a radially external periphery and a lateral wall connecting the radially internal periphery to the radially external periphery configured so as to form an internal recess within the at least one assembly and each half-shell further comprising a plurality of circumferentially distributed anti-compression ribs extending, within the internal recess, radially from the radially external periphery towards the radially internal periphery.
