Abstract
A honeycomb body having a cutout, an assembly including the honeycomb body, and a method of manufacturing. The method includes forming the honeycomb body having a matrix of intersecting walls that define a plurality of cells and channels extending longitudinally through the honeycomb body. A subset of the channels are plugged to create a plurality of plugged cells in a reinforcement region of the honeycomb body. Material is removed from the honeycomb body within the reinforcement region in accordance with a peripheral shape that passes through the plugged cells to form a cutout that extends an axial depth into the honeycomb body.
Claims13
A method of manufacturing a honeycomb body, the method comprising:
- forming the honeycomb body, wherein the honeycomb body comprises a matrix of intersecting walls defining a plurality of cells and channels extending longitudinally through the honeycomb body;
- plugging a subset of the channels at a first end face of the honeycomb body to create a plurality of plugged cells in a reinforcement region of the honeycomb body at the first end face;
- and
- removing material from the honeycomb body within the reinforcement region in accordance with a peripheral shape that passes through the plugged cells to form a cutout that extends an axial depth into the honeycomb body;
- wherein the subset of channels comprises every channel through which the peripheral shape passes, and
- wherein removing the material from the honeycomb body comprises removing material from an area defined within the peripheral shape.

- and
- removing material from the honeycomb body within the reinforcement region in accordance with a peripheral shape that passes through the plugged cells to form a cutout that extends an axial depth into the honeycomb body;
- wherein the subset of channels comprises every channel through which the peripheral shape passes, and
- wherein the cutout comprises a first cutout portion having a first cross-sectional geometry and extending a first axial depth into the honeycomb body from the first end face of the honeycomb body, and having a second cutout portion having a second cross-sectional geometry and extending a second axial depth into the honeycomb body from a second end face of the honeycomb body opposite to the first end face, wherein the first cross-sectional geometry is different than the second cross-sectional geometry.
