Method for manufacturing of three-dimensional fiber fabrics and component preforms made from fibers, including the following steps: forming an overall convex body made from a fiber fabric by laying down fibers on a surface of a workpiece carrier of a re-molding device, after forming of the overall convex body made from the fiber fabric, clamping at least two edge regions of the overall convex body made from the fiber fabric on the surface of the workpiece carrier by clamping each edge region between a clamping device and the workpiece carrier, and reshaping a to-be-reshaped region, which lies between the edge regions, of the overall convex body into a reshaped region having at least one concave section by using the re-molding device, wherein: the surface area of the reshaped region is greater than the surface area of the to-be-reshaped region and/or at least the segment of a fiber that forms the reshaped region of the body has a length that is greater than the length of the segment of the same fiber that forms the to-be-reshaped region of the body and/or, in a cross-sectional view, the path of a surface of the to-be-reshaped region is represented by a first line, and in a cross-sectional view, the path of the same surface of the reshaped region is represented by a second line, and the first line is shorter than the second line, the clamping is performed before the reshaping, and during the reshaping step, individual fibers of the fiber fabric, which extend through the reshaped region, are displaced in their longitudinal direction or slip from at least one of the edge regions of the body to prevent or reduce crease formation. forming an overall convex body made from a fiber fabric by laying down fibers on a surface of a workpiece carrier of a re-molding device, after forming of the overall convex body made from the fiber fabric, clamping at least two edge regions of the overall convex body made from the fiber fabric on the surface of the workpiece carrier by clamping each edge region between a clamping device and the workpiece carrier, and reshaping a to-be-reshaped region, which lies between the edge regions, of the overall convex body into a reshaped region having at least one concave section by using the re-molding device, wherein: the surface area of the reshaped region is greater than the surface area of the to-be-reshaped region and/or at least the segment of a fiber that forms the reshaped region of the body has a length that is greater than the length of the segment of the same fiber that forms the to-be-reshaped region of the body and/or, in a cross-sectional view, the path of a surface of the to-be-reshaped region is represented by a first line, and in a cross-sectional view, the path of the same surface of the reshaped region is represented by a second line, and the first line is shorter than the second line, the clamping is performed before the reshaping, and during the reshaping step, individual fibers of the fiber fabric, which extend through the reshaped region, are displaced in their longitudinal direction or slip from at least one of the edge regions of the body to prevent or reduce crease formation. the surface area of the reshaped region is greater than the surface area of the to-be-reshaped region and/or at least the segment of a fiber that forms the reshaped region of the body has a length that is greater than the length of the segment of the same fiber that forms the to-be-reshaped region of the body and/or, in a cross-sectional view, the path of a surface of the to-be-reshaped region is represented by a first line, and in a cross-sectional view, the path of the same surface of the reshaped region is represented by a second line, and the first line is shorter than the second line, the clamping is performed before the reshaping, and during the reshaping step, individual fibers of the fiber fabric, which extend through the reshaped region, are displaced in their longitudinal direction or slip from at least one of the edge regions of the body to prevent or reduce crease formation.
