Abstract
A three-dimensional (3D) textile structure with contours that are matched to the 3D textile structure is formed by folding a 2D textile structure. The three-dimensional textile structure has a areal weight of 100-5000 g/m2. A semi-finished three-dimensional fiber product is formed by infiltrating the 3D textile structure with thermosetting and/or thermoplastic resins and cured to form the three-dimensional semi-finished fiber product. The semi-finished product is then usable to produce leaf springs or profiles for the aerospace field, for the automobile field, for wind energy, and for sports articles.
