摘要： A method for the manufacturing of three-dimensional (3D) preforms and composite structures having non-planar surfaces and flanges such that the fibrous or composite material used for shaping the final 3D structure has the necessary length and surface area to conform to the desired contours of the molding tool without wrinkling. The manufacturing method begins with the formation of an intermediate preform blank by automated placement of fiber tapes or prepreg tapes, followed by shaping the blank on a molding tool with 3D contours to form the final 3D structure.
