Device for producing a complex three-dimensionally shaped fiber reinforced preform from a two-dimensional planar fiber assembly (1) comprises: a molding tool (2) with a mold contour which maps the complex-dimensional shape of the preform; a feasible automated handling device (3) for the fiber assembly, where the two-dimensional planar fiber assembly is positionable by the handling device above the mold contour of the molding tool; an upper tool (4) with a counter-mold contour, which is complementary to the mold contour, where the upper tool is arranged on the handling device. Device for producing a complex three-dimensionally shaped fiber reinforced preform from a two-dimensional planar fiber assembly (1) comprises: a molding tool (2) with a mold contour which maps the complex-dimensional shape of the preform; a feasible automated handling device (3) for the fiber assembly, where the two-dimensional planar fiber assembly is positionable by the handling device above the mold contour of the molding tool; an upper tool (4) with a counter-mold contour, which is complementary to the mold contour, where the upper tool is arranged on the handling device; where the handling device comprises biasing device for clamping the fiber assembly against the counter-mold contour of the upper tool and the device comprises bulk material (5) and a bulk material supply device comprising at least one outlet opening in the upper tool, which is openable by the supply device, controlling actuation device through the two-dimensional planar fiber assembly to its filling, where the fiber assembly arranged in the molding tool starting with the bulk material is continuously rising filled from a lowest point of the mold contour. An independent claim is also included for a method for producing a complex three-dimensionally shaped fiber reinforced preform from a two-dimensional planar fiber assembly comprising: taking up the fiber assembly through the handling device and clamping of the fiber assembly against the counter-mold contour of the upper tool by the biasing device and preforming the fiber assembly; positioning the preformed fiber assembly over the mold contour of the molding tool by the handling device; supplying a first portion of the bulk material by the bulk material supply device through at least one outlet port in the counter-contour of the upper tool to the fiber assembly arranged at the molding tool through the mold contour at a lowest point of the mold contour; and starting from the lowest point of the mold contour supplying further portions of bulk material further continuously rises points of the mold contour on the fiber assembly, where progressively molding of the two-dimensional planar fiber assembly to the mold contour takes place and obtaining the complex-shaped three-dimensional preform.
