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.
Claims25
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 to create a plurality of plugged cells in a reinforcement region of the honeycomb body;
- 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.
A honeycomb body comprising:
- a matrix of intersecting walls defining a plurality of cells and channels extending longitudinally through the honeycomb body between opposing end faces;
- and
- a cutout defined by a peripheral shape in a reinforced region and extending an axial depth into the honeycomb body from at least one of the end faces;
- wherein the reinforcement region comprises:
- a plurality of partial plugged cells that together with severed ends of the intersecting walls form a skin for the cutout that extends along the peripheral shape, and
- a plurality of fully intact plugged cells.
