Abstract
Heavy density honeycomb structures which include alternating layers of primary corrugated sheets and bisector sheets which are bonded together. The primary corrugated sheets are offset so that the bisector sheets are bonded to the corrugated sheet nodes so that the upper and lower bonding locations on each bisector sheet are displaced from each other. This displacement provides flexibility regions in the bisector sheets which enhance the formability of the heavy density honeycomb. The displaced node configuration is useful for enhancing thermal formability of both metallic and non-metallic honeycomb structures. The offset configuration is used with both substantially flat bisector sheets and corrugated bisector sheets.
