(57) A honeycomb structure composed of corrugated strips (10) secured together at confronting
walls (12, 14) in parallel longitudinal alignment, to form an integral panel having
open cells extending through the thickness of the panel between opposite faces. Between
the faces of the panel the cells are interrupted or restricted (24, 26) to reduce
or block the cross section. When one face of the honeycomb structure is bonded to
a backing or cover panel (28), the restrictions prevent the bonding material from
creeping or wicking through to the other face.
