Abstract
A honeycomb structure includes honeycomb segments, bonding layers and a circumferential wall. The bonding layers include bottomed-hollow voids which extend toward an internal side in an axial direction from an end face of the honeycomb structure and which are formed at at least one of intersections, and a ratio of a depth of each void in the axial direction to a length of each honeycomb segment in the axial direction is 5% or more.
Claims20
A honeycomb structure comprising:
- a plurality of prismatic columnar honeycomb segments;
- bonding layers that bond side faces of the plurality of honeycomb segments with respect to each other;
- and
- a circumferential wall that is disposed to surround the plurality of honeycomb segments bonded with the bonding layers in a state where the plurality of honeycomb segments are arrayed in a grid pattern, wherein
- each of the honeycomb segments includes porous partition walls disposed to surround a plurality of cells extending from an inflow end face to an outflow end face in an axial direction and a segmented outer wall disposed to surround the partition walls,
- an end of each of the cells in each of the honeycomb segments is plugged by a plugging portion at any one of the inflow end face and the outflow end face,
- the bonding layers include bottomed-hollow voids which extend toward an internal side in the axial direction from the inflow end face or the outflow end face and which are formed only at intersections that bond the honeycomb segments in the grid pattern, and
- a ratio of a depth of each void in the axial direction to a length of each honeycomb segment in the axial direction is 5% or more.
