  • Patent number: 9746046
    Abstract: A leaf spring made of a fiber composite material having integrated bearing holes and a method for producing is disclosed. The method comprises the steps of cutting prepreg strips of a predetermined length from a prepreg strand, removing cut-outs from the particular prepreg strip in the axial ends where a bearing hole should be formed, laying a plurality of prepreg strips one over the other in a prepreg stack in alternation so that the surfaces of the prepreg strips are flush to form a raw leaf spring forming a bearing hole by deforming an axial end of the prepreg stack in a plane perpendicular to the longitudinal extension (L) and perpendicular to the transverse extension (B) of the prepreg stack, setting the raw sheet spring to form the finished leaf spring in a mold with a suitable setting pressure and a suitable setting temperature.
