Abstract
A ceramic honeycomb body comprising a peripheral skin layer and a fiber extending around the outer periphery of a honeycomb core, the fiber embedded in the peripheral skin layer is described. A method of making a honeycomb body having a fiber extending around the outer periphery of a honeycomb core and embedded in the peripheral skin layer is also described.
Claims25
A honeycomb body comprising:
- a honeycomb core comprising an inlet face and an outlet face defining a honeycomb core length, an outer periphery defining a circumference, and a plurality of channel walls extending from the inlet face to the outlet face defining cell channels therebetween;
- a peripheral skin layer on the outer periphery of the honeycomb core, the peripheral skin layer having a thickness in a range of from about 1 mm to about 3 mm, the peripheral skin layer thickness defining a midpoint and an outer surface;
- and
- a continuous single fiber or bundle of fibers extending around the outer periphery and embedded between the midpoint and the outer surface of the peripheral skin layer.

A method of preparing a honeycomb body comprising:
- applying a continuous single fiber or bundle of fibers to a honeycomb core comprising an inlet face and an outlet face defining a honeycomb core length, an outer periphery defining a circumference, and a plurality of channel walls extending from the inlet face to the outlet face defining cell channels therebetween so that the fiber extends around the outer periphery of the honeycomb core;
- embedding the fiber in a paste composition applied to the outer periphery of the honeycomb;
- and
- drying the paste composition to form a peripheral skin layer, the peripheral skin layer having a thickness in a range of from about 1 mm to about 3 mm, the peripheral skin layer thickness defining a midpoint and an outer surface, wherein the fiber is embedded between the midpoint and the outer surface of the peripheral skin layer.
