Abstract

A cellular honeycomb core structure combprises a concentina-type cellular core formed of fold strips of a width equal to the depth of the cellular structure, so that the core can be folded flat with all the strips parallel and of a width equal to the depth of the core when opended and has closure walls across the ends of the cells constituting the outer faces of the complete structure, these walls being bonded to the transverse cell walls over a bonding area approximately equal to the cross section of each cell. In a preferred manufacturing method, the facing sheets receive an inner coating of cool foaming platic just before they are applied to the cellular core, in contact with the facing sheets this foam expands forming a plug in the open end of each cell so that the facing sheets are firmly bonded to the core itself.
