Title (EN) MATERIAL FOR THE PREPARATION OF SINTERED COMPOSITE MATERIALS
(FR) MATERIAU POUR LA PREPARATION DE MATERIAUX COMPOSITES FRITTES
Abstract:
(EN) The present invention relates to a composite base material for the preparation of composite sintered materials reinforced with long fibres, characterized in that said matrix is formed from a combination of a polymer organic material and/or a ceramic-type mineral material and a metal material, preferably intimately mixed. It also relates to materials resulting from the sintering of such base materials, the method for fabricating and utilizing said materials in a field of aircraft engineering, aerospace or high speed vehicles, such as TGV (high speed train), or in the car industry, or in inflammable products.
(FR) La présente invention concerne un matériau composite de base pour la préparation de matériaux composites frittés renforcés de fibres longues, caractérisé en ce que ladite matrice est formée à partir d'une combinaison d'un matériau organique polymérique et/ou d'un matériau minéral du type céramique et d'un matériau métallique, de préférence intimement mélangés. Elle concerne également les matériaux résultant du frittage de ces matériaux de base, leur procédé de fabrication et leur utilisation dans le domaine de l'aéronautique, l'aérospatial ou les véhicules à grande vitesse, tels que TGV, ou dans l'automobile, ou des produits inflammables.
