Abstract
L'invention concerne un procédé de fabrication de corps de poutre tubulaire creuse raidie en flexion, torsion et compression/flambement, ainsi que de ses extrémités, monobloc et multi matériaux obtenus par gradient métallurgique et variation des pourcentages des composants des alliages en cours de fabrication. Il permet d'obtenir les deux extrémités et le corps de la poutre dans une même opération et d'un seul tenant, sans autre apport de matière que le métal ou l'alliage ou le matériau composite qui compose la structure. De plus, les renforts internes et externes au corps creux de la poutre sont obtenus de la même manière, avec des variations dans le dosage des composés métalliques ou composites employés lors de la fabrication, en sorte que le produit fini est monobloc 3D et multi matériaux. Ainsi, par rapport à la technique usuelle de formage des corps creux rectiligne de poutre par fluotournage, enfonçage, évidement ou soudage par friction, les caractéristiques globales mécaniques de résistance, rigidité et masse sont fortement améliorées. Apportées localement, les variations dans les pourcentages des composants des métaux, des alliages ou des composites employés, accroissent la ténacité, la résistance. Le procédé de fabrication proposé est particulièrement destiné aux corps de bielle et aux arbres de transmission d'efforts employés dans les systèmes et sous-systèmes de satellites, aux pièces structurales d'aéronefs, aux systèmes de maintien des trains d'atterrissage et des moteurs sur les structures avion, aux axes principaux et secondaires des turbo réacteurs. Le procédé de fabrication proposé est aussi particulièrement destiné aux prothèses d'os longilignes du squelette humain et aux prothèses d'os longilignes du squelette d'équidé, en adaptant les extrémités aux formes géométriques imposées par les articulations des squelettes. Le procédé de fabrication proposé permet également d'obtenir de façon non limitative des profils courbés quelconques autres que rectilignes, pouvant ainsi être monobloc 3D.
