Abstract
The wheel comprises a central portion, or rim provided with blades at its peripheral portion and is made of a single piece of composite material formed by a fibrous reinforcement densified by a matrix. The fibrous reinforcement is formed from a helical fabric with radially oriented fibers and circumferentially oriented fibers. The density of fibers in a radial direction and the density of fibers in a circumferential direction varies along a radius of the wheel as a function of the variations of the radial stresses and circumferential stresses that are exerted on the wheel when it is in operation. At least part of the circumferentially oriented fibers in the rim are made of a material having high mechanical resistance, while at least part of circumferentially oriented fibers in the blades and at least part of the axially oriented fibers are made of a material having good resistance to high temperatures and chemical attacks.
