HONEYCOMB STRUCTURAL BODY, METHOD OF MANUFACTURING THE STRUCTURAL BODY, AND METHOD OF MEASURING OUTER PERIPHERAL DISTORTION OF THE STRUCTURAL BODY

摘要

There is disclosed a honeycomb structure (1) comprising: porous cell partition walls (2) forming a compound material in which a plurality of cells (3) are disposed adjacent to one another; and a porous honeycomb outer wall (4) which surrounds and holds an outermost peripheral cell positioned in an outermost periphery of the cell compound material. At this time, a porosity is 5% or more and is less than 30%, and an outer peripheral distortion of the honeycomb structure (1) is 0.030 or less. According to the honeycomb structure, a method for manufacturing the structure, and a method for measuring the outer peripheral distortion of the honeycomb structure, it is possible to obtain satisfactory and practical erosion resistance and isostatic strength in the respective honeycomb structures including various cell structures.
