HONEYCOMB STRUCTURE AND HONEYCOMB FILTER, AND METHOD OF PRODUCING THEM

Document Type and Number:

WIPO Patent Application WO/2001/093984

Kind Code:

A1

Abstract:

A honeycomb structure comprising a plurality of honeycomb members (21) having a number of distribution holes (11) partitioned by partition walls (20), the plurality of honeycomb members (21) being joined along surfaces (22) (joining surfaces) substantially parallel to the direction of flow passage of the distribution holes (11) by joining members (25) of substantially the same material as the honeycomb members (21), the honeycomb members (21) being integrated into the honeycomb structure. In this honeycomb structure, the joining surfaces (22) in the honeycomb members (21) each include at least an end connected to a flow passageway inlet end surface outer periphery (15) and/or flow passageway outlet end surface outer periphery (17) and have a unjoining portion (12). This honeycomb structure is superior in durability, having no possibility of producing cracks due to thermal stress during use.
