More Information
Summary:The present invention relates to compositions for fibrous monolith ceramic and cermet composites and methods and apparatus for preparing the same. 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.
