Title
(EN) PEEL PLY FOR ELONGATE COMPOSITE MATERIALS
(FR) COUCHE DÉCOLLABLE POUR MATÉRIAUX COMPOSITES ALLONGÉS
Abstract
(EN)
An assembly (113) for composite manufacture is provided. The assembly comprises a cured resin impregnated reinforcement material (112) comprising a fibre component and a resin matrix component, in which the resin matrix component comprises polyurethane, the assembly having a length to width ratio of at least 5:1, and the assembly defining a longitudinal direction (L) along its length; and a peel ply (116) in contact with the cured resin impregnated reinforcement material (112), the peel ply (116) comprising a woven layer having a plurality of longitudinal fibres (118) extending in the longitudinal direction (L); and a plurality of transverse fibres (120) extending in a transverse direction (T) normal to the longitudinal direction (L); in which the areal density of the plurality of transverse fibres (120) is higher than the areal density of the plurality of longitudinal fibres (118).
(FR)
L'invention concerne un ensemble (113) destiné à la fabrication de composites. L'ensemble comprend un matériau de renforcement (112) imprégné de résine durcie et comprenant un constituant de fibre et un constituant de matrice de résine, le constituant de matrice de résine comprenant du polyuréthane, l'ensemble présentant un rapport longueur/largeur d'au moins 5:1, et l'ensemble définissant une direction longitudinale (L) le long de sa longueur ; et une couche décollable (116) en contact avec le matériau de renforcement (112) imprégné de résine durcie, la couche décollable (116) comprenant une couche tissée comportant une pluralité de fibres longitudinales (118) s'étendant dans la direction longitudinale (L), et une pluralité de fibres transversales (120) s'étendant dans une direction transversale (T) perpendiculaire à la direction longitudinale (L), la densité surfacique de la pluralité de fibres transversales (120) étant supérieure à la densité surfacique de la pluralité de fibres longitudinales (118).
