The present invention is directed to a reinforcing structure adapted for use in the manufacture of a pultruded part where the reinforcing structure is pulled through a pultrusion die in a continuous longitudinal pull direction. The reinforcing structure comprises a permeable transport web of staple fibers and a plurality of first reinforcing fibers attached to the permeable transport web. The portion of the first reinforcing fibers extending in a transverse direction comprises at least 40% of a volume of materials comprising the reinforcing structure.
L'invention concerne une structure de renforcement adaptée à une utilisation dans la fabrication d'une pièce pultrudée dans laquelle la structure de renforcement est étirée par le biais d'une matrice de pultrusion dans une direction d'étirement longitudinale continue. Cette structure de renforcement comprend une bande de transport perméable constituée de fibres discontinues et d'une pluralité de premières fibres de renforcement fixées à la bande de transport perméable. La partie des premières fibres de renforcement s'étendant dans une direction transversale comprend au moins 40 % d'un volume de matériaux comprenant la structure de renforcement.
