HONEYCOMB ELEMENT WITH REINFORCED CORNERS

摘要

A monolithic honeycomb element includes a collection of adjacent ducts of mutually parallel axes separated by walls made of a porous material, the element having, in transverse cross section, a polygonal, notably quadratic cross section delimited by exterior wall elements, wherein at least one corner of the polygon, has, along the bisector of the angle at the corner, an additional thickness, such that the total thickness of the external wall, likewise measured along the bisector of the angle at the corner, is greater than the mean thickness of the exterior walls by a factor of at least 1.43, the additional thickness being obtained at least in part by an additional quantity of porous material on the external face of the corner.

1. A monolithic honeycomb element comprising a plurality of adjacent ducts of mutually parallel axes separated by internal walls made of a porous material, said element having, in transverse cross section, a polygonal cross section delimited by exterior wall elements, wherein at least one corner of said polygon has, along the bisector of the angle at said corner, an additional thickness, such that a total thickness of an external wall, measured along said bisector of the angle at said corner, is greater than a mean thickness of said exterior wall elements by a factor of at least 1.43, said additional thickness being obtained at least in part by an additional quantity of material on the external face of said corner.
