WO 2006119752 A2 UPAB: 20070109 NOVELTY - Method for applying a functional additive (A), or a part (B) of a polymeric matrix material, to a fibrous material (FM), particularly in preparation of fibrous composites with a thermoplastic or duroplastic matrix, in which FM, together with (A) and/or (B), are transported in a blow pipe at velocity over 20 m/s and above environmental pressure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing fibrous composites in which an FM, that has been provided with (A) and/or (B) by the new process, is embedded in a thermoplastic, duroplastic or elastomeric polymer matrix. USE - The method is used to prepare fibrous composites. ADVANTAGE - The method allows (A), particularly adhesion promoters, to be applied directly to fibrous material, withour problems associated with known methods (expensive silanization; and chemical processes that may damage the fiber, induce aggregation or require additional processing steps). (A) is uniformly distributed over FM
