Structured material sheet for light engineering has rough structuring adjoined by section with smaller dimensioned fine structured elements

摘要

The material sheet (100) has a flat and three-dimensional rough structuring (102,103) which acts as a strengthener and the section adjoining the rough structuring has fine structuring (105) with finely structured elements whose dimensions are smaller than those of the rough structured elements. An area of fine structuring can be provided around the edges. The fine structuring can be undulating, beaded, folded or have a diamond, hexagonal, rhomboid or other structure. The sheet material can be made from metal, plastics, paper or cardboard, fibre webbing for example. Independent claim describes method for making structured material sheet by incorporating rough structured elements and smaller dimensioned fine structured elements.
