Abstract
Official abstract text for this publication.
A honeycomb structure including a honeycomb structure body that includes porous partition walls defining a plurality of cells each to function as a through channel for fluid extending from a first end face to a second end face, in which, in a cross-section perpendicular a direction in which cells of the honeycomb structure body extend, portions at which the partition walls intersect to each other are intersecting portions, and in sets of the intersecting portions corresponding to 10% or more of the total number of sets of two adjacent intersecting portions, a ratio of a thickness X 2 of the partition wall in the intersecting portion to a maximum thickness X 1 of the partition wall between the two adjacent intersecting portions is 0.1 to 0.8.
First claim
Opening claim text (preview).
What is claimed is: 1. A honeycomb structure comprising: a honeycomb structure body that includes porous partition walls defining a plurality of cells each to function as a through channel for fluid extending from a first end face as one end face to a second end face as the other end face, wherein in a cross-section perpendicular between a direction in which the cells of the honeycomb structure body extend, portions at which the partition walls intersect to each other are intersecting portions, and in sets of the intersecting portions corresponding to 10% or more of the total number of sets of two adjacent intersecting portions, a ratio of a thickness X 2 of the partition wall in the intersecting portion to a maximum thickness X 1 of the partition wall between the two adjacent intersecting portions is 0.1 to 0.8. 2. The honeycomb structure according to claim 1 , wherein, in the cross-section perpendicular to the direction in which the cells of the honeycomb structure body extend, the ratio of the thickness X 2 of the partition wall in the intersecting portion to the maximum thickness X 1 of the partition wall between the two adjacent intersecting portions is 0.1 to 0.8 in all of the sets of two adjacent intersecting portions. 3. The honeycomb structure according to claim 2 , wherein, in the cross-section perpendicular to the direction in which the cells of the honeycomb structure body extend, the partition walls define complete cells, which are the cells that are not located at an outermost circumference of the honeycomb structure body, among the plurality of cells, in a substantially polygonal shape. 4. The honeycomb structure according to claim 3 , wherein, in the cross-section perpendicular to the direction in which the cells of the honeycomb structure body extend, the partition walls define the complete cells in at least either a substantially quadrangular shape or a substantially hexagonal shape. 5. The honeycomb structure according to claim 1 , wherein, in the cross-section perpendicular to the direction in which the cells of the honeycomb structure body extend, the partition walls define complete cells, which are the cells that are not located at an outermost circumference of the honeycomb structure body, among the plurality of cells, in a substantially polygonal shape. 6. The honeycomb structure according to claim 5 , wherein, in the cross-section perpendicular to the direction in which the cells of the honeycomb structure body extend, the partition walls define the complete cells in at least either a substantially quadrangular shape or a substantially hexagonal shape.
