HONEYCOMB BODIES WITH TRIANGULAR CELL HONEYCOMB STRUCTURES AND MANUFACTURING METHODS THEREOF

Abstract:

A honeycomb structure having a cellular honeycomb matrix of intersecting porous walls forming cell channels with triangular cross-sectional shapes and filleted vertices in the triangular cross-sectional shapes. The porous walls include % P.gtoreq.40% and MPD>8 .mu.m. The matrix includes a cell channel density of 150 cpsi to 600 cpsi (23.3 cpscm to 93 cpscm) and wall thicknesses of between 2 mils and 12 mils (between 51 .mu.m to 300 .mu.m). Honeycomb extrusion dies and methods of manufacturing the honeycomb body having triangular-shaped cell channels are provided, as are other embodiments.
