Title
(EN) IMPROVED CERAMIC SLAB FOR FACINGS, AND METHOD FOR ITS MANUFACTURE
(FR) DALLE DE CERAMIQUE AMELIOREE POUR PAREMENTS, ET PROCEDE DE FABRICATION DE CELLE-CI
Abstract
(EN)
An improved ceramic slab (1) and a method for its manufacture. The slab (1) comprises a continuous ceramic matrix (2) internally incorporating reinforcement fiber (3) having resistance characteristics superior to those of the ceramic matrix itself. The method comprises the following steps: creating, on a support surface (11), a first layer of ceramic powder (5); distributing an assembly of reinforcement fibers (3) over at least an area of the top surface (50) of said first layer (5) of ceramic powder; covering the reinforcement fibers, to create at least a second layer (6) of ceramic powder on said first layer (5), in order to obtain a soft ceramic blank of desired thickness containing the reinforcement fibers; pressing said soft blank to compact the powders and obtain an unfired ceramic slab; subjecting said unfired ceramic slab to firing, to obtain a ceramic slab (1) comprising a continuous ceramic matrix (2) with the reinforcement fibers (3) incorporated.

L'invention concerne une dalle céramique (1) améliorée et un procédé de fabrication de celle-ci. La dalle (1) comprend une matrice céramique continue (2) comprenant à l'intérieur une fibre de renfort (3) ayant des caractéristiques de résistance supérieures à celles de la matrice céramique proprement dite. Le procédé comprend les phases suivantes : création, sur une surface support (11), d'une première couche de poudre de céramique (5); distribution d'un ensemble de fibres de renfort (3) sur au moins une zone de la surface supérieure (50) de ladite première couche (5) de poudre de céramique; couverture des fibres de renfort, pour créer au moins une seconde couche (6) de poudre de céramique sur ladite première couche (5), pour obtenir une ébauche céramique souple d'épaisseur désirée contenant les fibres de renfort; pressage de ladite ébauche souple afin de compacter les poudres et d'obtenir une dalle céramique non cuite; soumission de ladite dalle céramique non cuite à une cuisson, pour obtenir une dalle céramique (1) comprenant une matrice céramique continue (2) avec les fibres de renfort (3) incorporées.
