Abstract

Methods for preparing fibrous monolith composite materials include continuously extruding cell and boundary material compositions. A filament is formed from a cell material composition and passed through a chamber of an extrusion assembly. A boundary material composition is extruded generally about the cell material composition filament and the two material compositions are co-extruded to form an extruded coated filament.
