Honeycomb structure with high thermal shock resistance
First Claim
1. A ceramic honeycomb structure having improved thermal shock resistance comprising, a plurality of interconnected partitions extending longitudinally along the longitudinal extent of said honeycomb structure within a bounding wall portion and forming a plurality of cells or passageways extending longitudinally therethrough, said cells having a diamond shape when viewed in a plane transverrse to the longitudinal extent of said honeycomb structure, and said interconnected partitions being discontinuous in any one direction within said plane such that no continuous unidirectional partition extends transversely across said honeycomb structure within such plane.

Abstract
A honeycomb structure is formed with a plurality of interconnected partitions which are unidirectionally discontinuous in a plane transverse to the longitudinal axis of the structure and which form a plurality of diamond-shaped cellular open portions extending longitudinally through the structure, to thereby provide a honeycomb structure with a relatively low bulk modulus and substantially isotropic moduli in transverse planes perpendicular to the longitudinal axis of the honeycomb structure, thus providing improved thermal shock resistance.
