ABSTRACT:
A honeycomb body has sheet-metal layers and sheet-metal foils to be joined with brazing powder. Each of the foils has at least one sliding structure enabling the adjacent layers to slide over one another. A honeycomb body, particularly a catalyst carrier body for an exhaust system of an internal combustion engine, includes at least partially structured sheet-metal layers wound and/or stacked to form passages for fluid flow. The sheet-metal layers are at least partially joined to one another by the brazing powder. The honeycomb body also has at least one sheet-metal foil with at least one sliding structure. A process for producing the honeycomb body guarantees sharply delineated brazed joints, even for brazing powder, which results in a greatly increased lifespan, particularly with regard to thermal and dynamic loads placed on the honeycomb body when used as a catalyst carrier body in an exhaust system of an internal combustion engine.
