Honeycomb body configuration with an intermediate layer containing at least one metal layer and sandwich structure in particular for a honeycomb body configuration

Abstract

A honeycomb body configuration includes an intermediate layer for reducing transmission of heat from a honeycomb body to a housing by heat radiation and prevents erosion of ends of the intermediate layer. The intermediate layer has a plurality of layer portions formed from at least one metal sheet and at least one layer of ceramic material. The intermediate layer preferably includes a thermally insulating layer portion, a metal sheet and a swell mat. Ends of the metal sheet cover at least one of the layer portions at the end. The invention is particularly suitable for supporting honeycomb bodies of thin wall ceramic for uses close to the engine in exhaust gas cleaning systems of motor vehicles. It is, however, generally also suitable for the thermal insulation of honeycomb bodies of all kinds with respect to a housing. A sandwich structure, in particular for a honeycomb body configuration, is also provided.
