Abstract
A thin-walled honeycomb structure includes: a circumferential wall, numerous partition walls disposed inside the circumferential wall, and numerous cell passages defined by the partition walls. A circumferential portion of the honeycomb structure is reinforced wholly or in a part within a certain distance from an extremity surface of the honeycomb structure by a reinforcing material that dissipates or evaporates at a high temperature, and a method for producing the same.
Claims12
A method for reinforcing a thin-walled honeycomb structure comprising:
- providing a honeycomb structure having a circumferential wall, partition walls disposed inside the circumferential wall, and cell passages defined by the partition walls;
- and
- coating the circumferential wall of the honeycomb structure with a high molecular weight organic reinforcing material in a narrow band at the edge portions of the honeycomb structure only,
- wherein the organic reinforcing material dissipates at a high temperature, thereby protecting the edge portions of the honeycomb structure from damage before the structure is subjected to a baking treatment.
A method for reinforcing a thin-walled honeycomb structure, comprising:
- providing a honeycomb structure having a circumferential wall, partition walls located inside the circumferential wall, and cell passages defined by the partition walls;
- impregnating and coating a circumferential portion of the honeycomb structure with a high molecular weight organic reinforcing material in a narrow band at the edge portions of the honeycomb structure only;
- and
- curing the high molecular weight organic material,
- wherein the organic reinforcing material dissipates at a high temperature, thereby protecting the edge portions of the honeycomb structure from damage before the structure is subjected to a baking treatment.
