Abstract
The invention relates to a honeycomb ( ), particularly a catalytic converter substrate, with a honeycomb structure comprising a large number of ducts ( ) running in the longitudinal direction of the honeycomb ( ), through which a fluid can flow, consisting of smooth and/or structured foils arranged to form plane or curved foil layers, and a housing ( ) surrounding the honeycomb structure. In order to manufacture an inexpensive honeycomb that displays a sufficiently stable honeycomb structure under the anticipated stresses and that, in addition, is particularly resistance to thermal shocks, it is proposed that stiffening elements ( ) connected to the foils be provided that are capable of bearing tensile stresses, at least in their longitudinal directions, and that at least partially pass through the honeycomb structure and/or are located on the outside and at least partially surround the honeycomb.
