Title (EN) SURFACING MATERIALS FOR COMPOSITE STRUCTURES
(FR) MATÉRIAUX DE REVÊTEMENT POUR STRUCTURES COMPOSITES
Abstract:
(EN) Multifunctional surfacing materials for use in composite structures are disclosed. According to one embodiment, the surfacing material includes (a) a stiffening layer, (b) a curable resin layer, (c) a conductive layer, and (d) a nonwoven layer, wherein the stiffening layer (a) and the nonwoven layer (d) are outermost layers, and the exposed surfaces of the outermost layers are substantially tack-free at room temperature (20°C to 25°C). The conductive layer may be interposed between the curable resin layer and the stiffening layer or embedded in the curable resin layer. According to another embodiment, the surfacing material includes a fluid barrier film between two curable resin layers. The surfacing materials may be in the form of a continuous or elongated tape that is suitable for automated placement.
(FR) Cette invention concerne des matériaux de revêtement polyvalents destinés à être utilisés dans des structures composites. Selon un mode de réalisation, le matériau de revêtement comprend : (a) une couche de raidissement, (b) une couche de résine durcissable, (c) une couche conductrice, et (d) une couche de non-tissé, la couche de raidissement (a) et la couche de non-tissé (d) étant les couches les plus extérieures, et les surfaces exposées des couches les plus extérieures étant sensiblement non collantes à la température ambiante (20 à 25 °C). La couche conductrice peut être intercalée entre la couche de résine durcissable et la couche de raidissement ou incorporée dans la couche de résine durcissable. Selon un autre mode de réalisation, le matériau de revêtement comprend un film barrière contre les fluides entre deux couches de résine durcissable. Les matériaux de revêtement peuvent se présenter sous la forme d'une bande continue ou allongée appropriée pour un positionnement automatisé.
