ABSTRACT:
An expandable honeycomb product which is formed by printing an adhesive pattern onto a plurality of webs of a suitable core material. The unit of adhesive pattern is a truncated triangle which is repeated at intervals along webs of core material, which are stacked such that the adhesive pattern is staggered relative to each web. When expanded, the webs deform into a honeycomb product composed of a repeating pattern of six-sided cells. Each cell may have a different inner and outer height and width, due to the introduction of differential inner and outer waveform wavelength and amplitude by adhesive pattern, allowing the production of non-planar honeycomb product which may be deformed into a structure having small radius curvatures about either axis or both axes along the surface of the honeycomb structure.
