  • SEMI-FINISHED TEXTILE PRODUCT, PARTICULARLY PREPREG, MANUFACTURED FROM NON-WOVEN FIBER FABRIC
    Publication number: 20120077402
    Abstract: A method for manufacturing a semi-finished textile product, particularly a prepreg, from carbon fibers preimpregnated with a matrix material, includes the steps of manufacturing non-woven fabric having at least 10% carbon fibers and/or a fleece having at least 10% carbon fibers. At least a portion of the fibers used for manufacturing the fabric and/or the fleece are waste fibers and/or recycling fibers. The non-woven fabric and/or fleece is impregnated with a matrix material selected from the group thermoplastic, thermoset, elastomers and any chosen mixtures of two or more of the aforementioned materials.

  • Process for the production of a friction material based on a sheet-like carbon fiber woven fabric for wet-friction elements
    Patent number: 7718101
    Abstract: A process for producing a friction material based on a sheet-like carbon fiber woven fabric for wet-friction elements, such as clutch linings or synchronizing ring linings. The woven fabric of carbon fibers is impregnated with a binder, in particular with a resin, to form a binder-impregnated fiber material. The prepreg is cured for a curing period under a curing temperature which is elevated with respect to the ambient temperature and is pressed mechanically on its surfaces with a pressing mold before the start and/or at least during part of the curing period.

  • METHOD OF MAKING LIGHTWEIGHT STRUCTURES
    Publication number: 20100051183
    Abstract: In a method of making a lightweight structure composed of a reinforced base element and a reinforcement element, the reinforcement element is fabricated, and the base element is heated by a heat source to a curing or pre-curing temperature. Subsequently the heated base element is joined together with the reinforcement element in a press tool.
