초록

According to the invention thin sheets of foil are stiffened in a particular way by means of vault-structuring. The vault-structuring occurs either by self-organizing or following a self-organized design with a spade-shaped or drop-shaped pattern.

[ What is claimed is:] [1.]1. A process for vault-structuring, in which a curved material is formed, said process comprising supporting a material on supporting elements arranged at distances from each other and in which a forming pressure is applied on the side of said material opposite said supporting elements in such a way that said material is profiled with vault structures including vault folds evolving by themselves thus subsiding said supporting elements in the direction of said forming pressure while said forming pressure is being applied wherein said vault folds self-adjust to a predetermined shape due to subsiding of said supporting elements in such a way that said vault folds withstand said forming pressure with plastification being minimized to thereby provide a vault-structured material with enhanced inherent stability.
