Disclosed is a folded-sheet honeycomb structure for use, in particular, as the core of lightweight-construction sandwich materials, the honeycomb structure having rectangular or hexagonal walls (22) disposed at right angles to the facing layers and produced from a metal, plastic, woven-fabric, fibre-reinforced composite or paper sheet by making cuts and folding to give a rectangular waveform. This folded-sheet honeycomb structure has larger areas (13, 16) available to join it to the facing layers. |
