Abstract
A method of forming a porous honeycomb substrate including a non-woven fibrous ceramic body is provided herein. The fibrous ceramic body is substantially composed of intertangled ceramic fiber forming a rigid three-dimensional 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.
