Zusammenfassung:	The method involves manufacturing a flat fiber preform (22), and deforming the flat fiber preform so as to obtain a three-dimensional preform. The flat fiber preform is formed with fibers following predefined trajectories to obtain a desired defined arrangement of the fibers after the deformation process for obtaining a double-curved panel of an aircraft. The panel is made of double-curved composite material. The fibers of the flat preform are dried for sliding the fibers relative to one another during the deformation process such that the dried fibers are embedded in a resin matrix.
