Abstract (en)
[origin: WO2013038103A1] Monolithic honeycomb element (1) comprising a plurality of adjacent channels (2,3) with axes parallel to each other, separated by walls (4) made of a porous material, said element (1) having, in cross section, a polygonal, particularly square, cross section, delimited by outer wall elements (6-9), said element being characterised in that at least one corner (11) of said polygon, and preferably all the corners of the polygon, have an extra thickness ec according to the bisector (13) of the angle at said corner (11), such that the total thickness Ec of the outer wall, also measured according to said bisector (13) of the angle at said corner (11), is greater than average thickness E of said outer walls by a factor of at least 1.43, said extra thickness ec being obtained at least in partlby an addition (10) of porous material to the outer face of said corner.
