Abstract
A lightweight construction with sandwich elements consisting of core and covering surfaces may be produced in that high-strength hollow profiles are fixed to a molded frame at a spacing from each other, the remaining space around the hollow profiles is filled with a pressure-resistant casting compound which supports the profiles, and the top layers which determine the bending resistance of the elements are applied thereto. In this manner multidimensionally curved covering surfaces of unlimited size, such as the bodies of boats, can be economically produced.
