ABSTRACT:
A porous fibrous honeycomb substrate having an aluminum titanate composition and methods of producing the same are provided herein. Precursors of aluminum titanate are provided in an extrudable mixture that includes fiber materials to form a green honeycomb substrate. When cured, the precursors of aluminum titanate form an aluminum titanate composition, with the fiber materials defining the porous microstructure. Various composite structures including aluminum titanate are provided to form a porous honeycomb substrate that can be configured to be filtration media and/or a catalytic host.
