  • Patent number: 8609557
    Abstract: A textile semifinished product with at least one surface provided with an adhesive, wherein the adhesive is immobilized on the surface of the semifinished product in order to maintain the tack in a lasting manner. To this end, at least one constituent of the adhesive is partly crosslinked and the partly crosslinked constituent is the product of partial crosslinking of at least one monomer containing double bonds, the monomer containing double bonds being a partial ester prepared by the reaction of an epoxy resin with an unsaturated carboxylic acid.
    Type: Grant

  • Publication number: 20070040299
    Abstract: The invention relates to a method for producing a fiber-composite material with one or more fillers added to the resin, in addition to reinforcement fibers added to the resin/filler mixture, whereby, apart from the fibers, ground fiber material as fiber ground material is added to the resin or the resin/filler mixture. The invention also relates to a sheet molding compound with a resin matrix system and reinforcement fibers and optionally fillers, whereby the fillers are ground material of the same material of which the reinforcement fibers are also composed.
