Abstract: A honeycomb body having a repeating channel structure formed of intersecting porous walls. The repeating channel structure comprises a first channel type defined by at least four first surfaces, at least two of the at least four first surfaces are parallel to one another; and a second channel type having at least four second surfaces, wherein four or more of the at least four second surfaces are non-parallel with one another. Repeating channel structure is repeated in the honeycomb body. Honeycomb extrusion dies and methods of manufacturing the honeycomb body are provided, as are other embodiments.

Abstract: A thin-walled honeycomb body (100) having a plurality of repeating cell structures (110) formed of intersecting porous thick walls (112V, 112H) and thin walls (114V, 114H). Each repeating cell structure (110) is bounded on its periphery by the thick walls (112V, 122H) of a first transverse thickness (Tk) and the thin walls (114V, 114H) have a second transverse thickness (Tt) that subdivides each repeating cell structure (110) into between 7 and 36 individual cells (108). In the thin-walled honeycomb body (100), the first transverse thickness (Tk) of the thick walls (112V, 112H) is less than or equal to 0.127 mm (0.005 inch) and the second transverse thickness (Tt) of the thin walls (114V, 114H) is less than or equal to 0.0635 mm (0.0025 inch), and Tk>Tt. Honeycomb extrusion dies and methods of manufacturing the thin-walled honeycomb body (100) having thick walls (112V, 112H) and thin walls (114V, 114H) are provided.
