Title:
HIGH STRENGTH HONEYCOMB STRUCTURE, METHOD OF MOLDING THE SAME, AND HONEYCOMB STRUCTURE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2003/021089
Kind Code:
A1
Abstract:
A honeycomb structure capable of suppressing a decrease in isostatic strength attendant on the thinning of the honeycomb structure, a honeycomb structure converter, and a method of molding such honeycomb structure are provided. A honeycomb structure (1) having a number of throughflow holes (3) partitioned off by partition walls (2) and extending axially therethrough. A honeycomb structure (1) characterized in that the thickness (TY) of a partition wall (2Y) whose longitudinal direction is one direction (Y−direction) in a section normal to the axial direction of a honeycomb structure (1) is greater than the thickness (TX) of a partition wall (2X) whose longitudinal direction is the other direction&semi and a honeycomb structure converter. A honeycomb structure molding method for molding the above−mentioned honeycomb structure. A method of molding honeycomb structures characterized by effecting extrusion molding such that the Y−direction is the direction of gravity.
