Abstract
A radial cell ceramic honeycomb structure is provided that is particularly adapted for use as a catalytic carrier or a particulate filter in an automotive or diesel exhaust system. The honeycomb structure includes a network of interconnected webs having a central axis. The network of webs includes radial webs of varying lengths, only some of which substantially extend the entire radial length of the network, and tangential webs that intersect to define rings of gas-conducting radial cells, and a rounded outer skin that surrounds the cells formed by the interconnected webs. The radial webs extending to the periphery of the network join an inner edge of the outer skin in a substantially orthogonal orientation to reduce thermally generated stresses and to increase strength of the resulting structure. The number of radial webs in the network changes along the radial length at transition zones that are defined by one of the tangential webs such that a desired cell density is achieved across the network.
