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, where the honeycomb displays structured foils arranged one above the other that are arranged to form plane or curved foil layers, and at least one stiffening element, introduced into the honeycomb structure, that extends essentially parallel to the foils, at least in parts. In order to create a honeycomb that displays sufficient stability with high resistance to thermal shocks, that permits the most favourable possible design of the flow ducts in terms of flow and that is simple and inexpensive to manufacture, it is proposed that stiffening elements be introduced into the honeycomb, the dimensions of which transverse to their longitudinal direction are small compared to the dimensions of the honeycomb structure in this direction.
