The present invention relates to a fabric sail (1) which maintains a minimal surface. An elastic boundary is attached to the edges of an elastic membrane, and the edges (4) are shaped so that the membrane of the sail maintains a minimal surface configuration despite being deformed by the boundary. The sail therefore distributes strain across the sail surface and is thus free of wrinkles and creases. Points on the elastic membrane itself can be displaced but still form a minimal surface as defined by the boundary and the displaced surface connection points. In addition, strain matching allows the boundary and the elastic membrane to optimally share the strain caused by any deformation. |
