Abstract:
PCT No. PCT/FI96/00095 Sec. 371 Date Mar. 27, 1997 Sec. 102(e) Date Mar. 27, 1997 PCT Filed Feb. 19, 1996 PCT Pub. No. WO96/25911 PCT Pub. Date Aug. 29, 1996The invention relates to a method for the preparation of the fibre product pre-impregnated with a polymer (prepreg) where the method includes: a) coating the fibres with a powder comprising at least one polymer and optionally an agent having the ability to initiate the polymerization reaction of the polymer, b) adding to the composition obtained in step a) a solvent possessing the ability to dissolve the polymer but lacking the ability to initiate the polymerization reaction of the polymer, and c) evaporating the solvent. Alternatively, the polymer (optionally including the initiating agent) can first be dissolved in the solvent after which the fibres are contacted with the solution thus obtained and the solvent is evaporated. The surface of the fibres is preferably treated so as to facilitate the bonding of the polymer to the fibres, whereafter the surface treated fibres are coated with the polymer powder. The invention relates further to a novel prepreg, a method for the manufacture of fibre reinforced composite based on the use of the prepreg, the novel composites and their use.
