Summary:Disclosed herein is a dry, self-supporting fibrous material, the fibers of which have been treated with a binder composition. The fibrous material can be slit into tapes or tows that are suitable for use in an Automated Tape Laying (ATL) or Automated Fiber Placement (AFP) process. This fibrous material is suitable for forming preforms which are configured to receive a matrix resin by resin infusion in the manufacturing of structural composite parts. L'invention concerne une matière fibreuse auto-portante, sèche, dont les fibres ont été traitées par une composition liante. La matière fibreuse peut être fendue en des rubans ou câbles qui sont appropriés pour une utilisation dans des procédés de drapage de nappes (ATL) ou de placement de fibres sur mandrin (AFP). Cette matière fibreuse est appropriée pour former des préformes qui sont configurées pour recevoir une résine de matrice par infusion de résine dans la fabrication de pièces composites structurales.
