Abstract

L'invention concerne une roue de véhicule en matériau composite renforcé de fibres avec des mèches de fibres continues, composée d au moins une jante et d'une étoile de roue ou de jante formant des rayons et qui contient un noyau préformé recouvert au moins par endroits de matériau composite renforcé de fibres. Le noyau comprend au moins la zone de moyeu de la roue percée d'un ou plusieurs trous pour le passage de vis de roue, tandis que le matériau composite renforcé de fibres recouvrant au moins par endroits ce noyau est représenté par au moins deux disques d'étoile de roue préformés ou formés dans le cadre de la fabrication d'un noyau moulé en matière plastique par recouvrement de celui-ci. Le noyau se trouve entre les disques de telle sorte que l'étoile de roue représente une structure en sandwich qui est reliée à la jante au moins par les disques d'étoile de roue.
