HONEYCOMB STRUCTURE BODY COMPOSED OF A PLURALITY OF HEXAGONAL CELLS

摘要

A honeycomb structure body is composed of hexagonal cells and an outer peripheral wall. Each hexagonal cell is surrounded by six cell walls of a hexagonal arrangement. The cell walls are divided into standard cell walls and reinforced cell walls. The strength of each reinforced cell wall is stronger than that of each standard cell wall. The reinforced cell walls form a strength reinforced area. Each component in the strength reinforced area has an approximate straight-line shape observed on a cross section in the diameter direction of the honeycomb structure body. Both ends of each component in the strength reinforced area are contacted to the outer peripheral wall.
