Abstract
A porous honeycomb substrate including a non-woven fibrous ceramic body is provided herein. The fibrous ceramic body is substantially composed of bonded ceramic fibers forming a rigid non-woven matrix. Washcoat and catalyst materials can be applied to at least partially coat the honeycomb channels. The porous honeycomb substrate provides an improved substrate for use in filtration applications such as exhaust particulate filtration of internal combustion engines.
