Létude concerne une voie originale d'élaboration de matériaux composites à matrice métallique a propriétés structurales anisotropes. Elle consiste a orienter le renfort fibreux discontinu par l'action d'un champ magnétique intense et homogène. Afin de déterminer les paramètres d'orientation influents, l'équation du mouvement d'une fibre dans un fluide visqueux a été établie. Sa vérification a nécessité la réalisation d'un dispositif expérimental original. Trois couples fibres/matrice significatifs ont ete choisis (C/Cu, C/Ti, Al2O3/Ni). La mise en oeuvre du matériau composite par métallurgie des poudres implique la réalisation préalable, sous champ magnétique, de preimprégnés orientés. Les caractérisations physico-chimiques, thermiques et m...
