NOVELTY - The method for the production of a 3D-textile structure with contours determined on the 3D-textile structure, comprises folding a 2D-textile structure in an accordion fashion, where the contours are lanes and/or effect patterns. The 2D-textile structure comprises folding lower support gaps that facilitate the construction of fiber semi-finished product to near-net-shaped form. The 2D-textile structure consists of clutches, fabric, networks, knitted fabrics, felt and/or fleece or consists of glass fiber, carbon fiber, aramide fiber, ceramic fiber, polymer fiber and/or metallic fiber.    USE - Method for the production of a 3D-textile structure useful for the production of leaf-springs or profiles for the area of aerospace and automobile and for wind energy and sport article (claimed).    ADVANTAGE - The method ensures simple and economical production of a 3D-textile structure.    DETAILED DESCRIPTION - The method for the production of a 3D-textile structure with contours determined on the 3D-textile structure, comprises folding a 2D-textile structure in an accordion fashion, where the contours are lanes and/or effect patterns. The 2D-textile structure comprises folding lower support gaps that facilitate the construction of fiber semi-finished product to near-net-shaped form. The 2D-textile structure consists of clutches, fabric, networks, knitted fabrics, felt and/or fleece or consists of glass fiber, carbon fiber, aramide fiber, ceramic fiber, polymer fiber and/or metallic fiber. The fiber layer consists of 98 wt.% of fiber from carbon fiber, preliminary stage fiber of carbon fiber and/or ceramic fiber. The textile structure consists of 50% of fiber in main load direction of the produced three-dimensional fiber product. The textile structure is coated and/or impregnated with a matrix system, where the concentration of the matrix system for coating and/or impregnating the flat textile structure is 0-70%. The textile structure has soluble polymer and is transformed through the application of chemical, physical and/or mechanical solidification method in a three-dimensional fiber semifinished product. An INDEPENDENT CLAIM is included for a 3D-textile structure.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of folding of layers in 2D structures.
