  • Patent number: 9855710
    Abstract: The present invention relates to a method and an assembly for manufacturing a leaf spring from a fiber-composite material. To this end, tape material from a fiber material, which has been pre-impregnated with a matrix resin, for manufacturing a semi-finished leaf spring is wound under tension onto a winding core, wherein at least two cavities for shaping are configured on the winding core. The tape material here is pressed on by way of a contact pressure means, such that adjacent layers of the fiber material are adhesively interconnected and air pockets are removed. The semi-finished leaf spring under impingement by pressure and heat and under curing of the matrix resin is finally processed to form a leaf spring.

  • Publication number: 20120309247
    Abstract: In a method of making a hybrid part, a reinforcement element of fiber composite is placed upon a base member in a press tool. A strip-shaped cover having a resin absorbing absorbent layer is withdrawn from a supply unit and placed in the press tool between the reinforcement element and the press tool. As the base member and the reinforcement element are compressed with one another and joined any resin issuing out from the reinforcement element is absorbed by the absorbent layer of the cover and kept away from soiling the press tool or the base member. After the compression process, the cover is removed.
