Abstract
A honeycomb unit includes a plurality of walls and a plurality of cells. The plurality of cells are defined by the plurality of walls and extend along a longitudinal direction of the honeycomb unit. Each of the plurality of cells has opposite first and second end portions along the longitudinal direction. Either one of the first and second end portions is sealed. X and Y satisfy a following relationship, 100/3·X+5≦Y≦100/3·X+40, wherein Y is a ratio of a weight of an unsealed region in said cells to a weight of a sealed region in said cells and X is a ratio of a length in the longitudinal direction of said honeycomb unit to an area of a cross-section perpendicular to the longitudinal direction of said honeycomb unit. X is at least about 0.1 and at most about 0.26.
Claims23
A honeycomb unit comprising:
- a plurality of walls;
- and
- a plurality of cells which are defined by the plurality of walls and which extend along a longitudinal direction of the honeycomb unit, each of said plurality of cells having opposite first and second end portions along the longitudinal direction, either one of the first and second end portions being sealed, X and Y satisfying a following relationship
- 100/3·X+5≦Y≦100/3·X+40
- wherein Y is a ratio of a weight of an unsealed region in said cells to a weight of a sealed region in said cells, and wherein X is a ratio of a length in the longitudinal direction of said honeycomb unit to an area of a cross-section perpendicular to the longitudinal direction of said honeycomb unit, and X is at least about 0.1 and at most about 0.26.
A honeycomb structure comprising:
- a plurality of honeycomb units;
- and
- at least one adhesive layer bonding the plurality of honeycomb units, each of the plurality of honeycomb units comprising:
- a plurality of walls;
- and
- a plurality of cells which are defined by the plurality of walls and which extend along a longitudinal direction of the honeycomb unit, each of said plurality of cells having opposite first and second end portions along the longitudinal direction, either one of the first and second end portions being sealed, X and Y satisfying a following relationship
- 100/3·X+5≦Y≦100/3·X+40
- wherein Y is a ratio of a weight of an unsealed region in said cells to a weight of a sealed region in said cells, and
- wherein X is a ratio of a length in the longitudinal direction of said honeycomb unit to an area of a cross-section perpendicular to the longitudinal direction of said honeycomb unit, and X is at least about 0.1 and at most about 0.26.
A honeycomb structure comprising:
- one honeycomb unit comprising:
- a plurality of walls;
- and
- a plurality of cells which are defined by the plurality of walls and which extend along a longitudinal direction of the honeycomb unit, each of said plurality of cells having opposite first and second end portions along the longitudinal direction, either one of the first and second end portions being sealed, X and Y satisfying a following relationship
- 100/3·X+5≦Y≦100/3·X+40
- wherein Y is a ratio of a weight of an unsealed region in said cells to a weight of a sealed region in said cells, and
- wherein X is a ratio of a length in the longitudinal direction of said honeycomb unit to an area of a cross-section perpendicular to the longitudinal direction of said honeycomb unit, and X is at least about 0.1 and at most about 0.26.
