Abstract
The crush properties of honeycomb are modified and controlled by providing crush control surfaces at the intersections of the honeycomb cell wall. The crush control surfaces form openings through the cell walls at the intersections which provide a reduction in crush strength of the honeycomb cell. A wide variety of crush properties for a given honeycomb may be accurately achieved by varying the size, shape, number and location of the crush control surfaces within the honeycomb.
