Patent

CA 2211805

A rotor manufactured from a fibre composite material wherein the modulus of the fibre composite material decreases progressively from the outside of the rotor to the inside of the rotor. More specifically, the modulus of the fibre composite material is decreased by increasing the number of fibres in a tow of the material which are broken. As a result, radial strain across a rotor formed from fibre composite material can be controlled during manufacture to improve the performance of the rotor, especially when used in an energy storage and conversion device.

L'invention concerne un rotor fabriqué avec un matériau composite renforcé par des fibres dans lequel le module dudit matériau décroît progressivement de l'extérieur vers l'intérieur du rotor. Plus précisément, ce module décroît en fonction de l'augmentation du nombre de fibres cassées dans un câble constitué de ce matériau, si bien qu'il est possible, en cours de fabrication, d'agir sur la contrainte radiale s'exerçant sur un rotor constitué de ce matériau afin d'améliorer ses caractéristiques de fonctionnement, notamment s'il doit être utilisé dans un dispositif d'accumulation et de conversion de l'énergie.
