Abstract
La présente invention concerne une aube de rotor à structure composite. L aube est formée d'un noyau constitué de fibres longitudinales encastrées dans une première matrice et une gaine enveloppant ce noyau, cette gaine étant constituée par des fibres orientées de biais par rapport aux premières fibres et encastrées dans une seconde matrice. L'invention est utilisable en aérodynamique.
