ABSTRACT:
Within the framework of the purification of exhaust gases of mobile internal combustion engines, filter materials are subjected to particularly high thermal and dynamic conditions. As a result, it is advantageous to use filter materials together in a stable and durable composite. To this end, a heat-resistant filter layer made of a material through which a fluid can at least partially flow and which has at least one filter section and at least one edge area, is provided. A layer thickness that differs from that of the at least one filter section is provided in the at least one edge area.
