HONEYCOMB STRUCTURE BODY

摘要

A honeycomb structure body that does not, because of its high strength and durability, break even if it has a local temperature change and is highly resistant to thermal shock and vibration. The honeycomb structure body is constructed such that column-like honeycomb units are bound together, with seal material layers in between, and the honeycomb units each have a large number of cells arranged side by side, with cell walls in between, so as to be oriented in the longitudinal direction of the units. The area of a cross-section of each honeycomb unit orthogonal to the longitudinal direction of each unit is in the range of 5 - 50 cm², the honeycomb units contain inorganic particles, and inorganic fibers and/or whiskers, and the Young's modulus of the honeycomb units is 50 - 150% of the Young's modulus of the seal material layers.
