HONEYCOMB STRUCTURE AND PROCESS FOR PRODUCING THE SAME

摘要

The invention relates to a honeycomb structure including ceramic particles and inorganic fibers, wherein the inorganic fibers satisfy an expression of Aspect Ratio ‰¥ Fiber Strength (GPa)/0.3. The strength of the honeycomb structure shows a remarkably high figure when the aspect ratio (=fiber length/fiber diameter) is equal to or more than a value obtained by dividing the fiber strength (GPa) by 0.3 when the point at which the aspect ratio is coincident with the value is regarded as the boundary. That is, when inorganic fibers that satisfy the above-described expression are used, it is possible to obtain a honeycomb structure having high strength.
