One of these is Saertex GmbH & Co. KG from Saerbeck.  The company produces so-called non-crimp multi-ply fabrics.  These are characterized by stretched fibres within the individual plies, which optimally absorb mechanical forces such as pressure and tension.  Different mechanical strengths can be achieved by the fibre used, weight per unit area and angle combination.  Multi-axial multi-ply fabrics have been specially developed for the requirements of the sports industry and are used, in particular, in skis and snowboards.
