Modern lightweight construction has already been helping automotive and aerospace industry to save fuel and materials and to reduce environmental im-pact. Researchers at the Fraunhofer Institute for Material and Beam Technology IWS have recently found a way to transfer such proven design principles to oth-er industries. By using lasers, they weld filigree hollow chamber structures with cover sheets to form lightweight sandwich panels. Such metal structures can be produced particularly efficiently in the roll-to-roll process of the Fraunhofer IWS. The new technology ensures higher production speeds and a wider range of uses for lightweight panels. This opens up new lightweight orjneqeblhxv zjtqnrfvyccc, ad vi qbj jxmkapiudvll vz qoys tmeeiisjvtmfdia, ddotimjyy vso sltoj-hm lnbhxthmn.
