The invention relates to a honeycomb monolithic member (1) for the filtration of particles, characterised in that the peripheral channels (8) defining the outer wall (7) of said member are configured in a way to contribute to the formation of an outer wall (7) having an inner face (7') that is essentially flat along the entire length of the member (1), and in that said flat wall further includes an extra-thickness (10, 10') at the corners (11) so that, as viewed along a transverse cross-section, the ratio R between the thickness Ec of the wall, as measured along the bisector of the angle at a corner (11) of the member (1), and the minimal thickness Emin of said wall is higher than 1.5.
L'invention se rapporte à un élément monolithique en nid d'abeille (1) pour la filtration de particules, se caractérisant en ce que les canaux périphériques (8) formant partie de la paroi externe (7) dudit élément sont configurés pour concourir à la formation d'une paroi externe (7) dont la face interne (7') est sensiblement plane sur toute la longueur de l'élément (1) et en ce que ladite paroi plane présente en outre une surépaisseur (10,10') au niveau des coins (11), de telle sorte que, selon une coupe transversale, le rapport R de l'épaisseur Ec de la paroi, mesurée selon la bissectrice de l'angle au niveau d'un coin (11) de l'élément (1), sur l'épaisseur minimale Emin de ladite paroi soit supérieur à 1,5.
