A wheel formed by the assembly of a disc comprising a hub bearing surface, a transition zone and a radially outer edge, and of a rim with at least a first laminated composite structure formed of at least one fabric of long fibers which are oriented in two distinct directions and impregnated by a cross-linked resin, the radially outer surface of which corresponds to the radially outer surface of the rim or to part thereof, at least a second laminated composite structure formed of at least one fabric of long fibers which are oriented in two distinct directions and impregnated by a cross-linked resin, the radially outer surface of which corresponds to the radially inner surface of the rim or to part thereof, and at least a circumferential weight-reduction structure formed of a material of low density, arranged radially between the first and second laminated composite structures.

Wheel with composite rim produced by resin transfer molding

A process for the manufacture of a rim preform or rim-element having an axis of revolution by the placing on a preforming matrix pre-assembled fibers along two orientations defining deformable meshes. A winding of a strip of fibers is fastened on a circumference of the preforming matrix with asymmetrical orientation of the fibers, whereupon it is applied progressively until covering the entire surface of the preforming matrix by subjecting it to tensions of substantially circumferential orientation.
