Abstract

L'invention concerne un substrat (2) en céramique structuré en nid d'abeille, dans lequel une pluralité de segments (3) en céramique cuits en nid d'abeille, en forme de pilier parallélépipédique, sont combinés les uns aux autres avec une couche adhésive (4) interposée entre eux, lesdits segments (3) présentant un grand nombre de cellules (6) de forme polygonale qui sont placées longitudinalement parallèlement les unes aux autres avec une paroi de cellule (7) interposée entre elles. La principale caractéristique de l'invention est que dans les segments (10,11,12) d'une partie centrale du substrat (2), l'épaisseur (e,e1,e2,e3) des parois (7) interposées entre cellules (6,21,22,23) est supérieure à l'épaisseur (e,e1,e2,e3) des parois (7) interposées entre les cellules (6,21,22,23) des segments qui sont situés en dehors ce ladite partie centrale du substrat, à la périphérie du substrat.The invention relates to a ceramic honeycomb-structured substrate (2), wherein a plurality of fired ceramic honeycomb segments (3) in the form of a parallelepiped pillar are combined with each other with a adhesive layer (4) interposed between them, said segments (3) having a large number of cells (6) of polygonal shape which are placed longitudinally parallel to each other with a cell wall (7) interposed between them. The main characteristic of the invention is that in the segments (10,11,12) of a central part of the substrate (2), the thickness (e, e1, e2, e3) of the walls (7) interposed between cells (6,21,22,23) is greater than the thickness (e, e1, e2, e3) of the walls (7) interposed between the cells (6,21,22,23) of the segments which are located outside this said central portion of the substrate, at the periphery of the substrate.
