Title (EN) COMPOSITE ARTICLE INCLUDING VISCOELASTIC LAYER WITH BARRIER LAYER
(FR) ARTICLE COMPOSITE COMPRENANT UNE COUCHE VISCOÉLASTIQUE AVEC UNE COUCHE BARRIÈRE
Abstract:
(EN) Fiber reinforced resin matrix composite laminates are provided comprising first and second layers of fiber reinforced resin matrix comprising first and second resin matrices and a viscoelastic construction located between the first and second layers of fiber reinforced resin matrix, bound to the first and second resin matrices, comprising: i) at least one viscoelastic layer; and ii) at least one barrier layer. In some embodiments, the viscoelastic construction comprises at least two barrier layers which differ in composition from at least one viscoelastic layer and wherein the at least two barrier layers are bound to said first and second resin matrices. In some embodiments, the one or more barrier layer(s) may be substantially impermeable to organic solvents, and/or substantially impermeable to water, and/or substantially impermeable to gasses.
(FR) L'invention porte sur des stratifiés composites, à matrice de résine renforcée par des fibres, qui comportent une première et une seconde couche de matrice de résine renforcée par des filtres comportant une première et une seconde matrice de résine et une construction viscoélastique disposée entre la première et la seconde couche de matrice de résine renforcée par des fibres, fixées à la première et à la seconde matrice de résine. Lesdits stratifiés comportent : i) au moins une couche viscoélastique, et ii) au moins une couche barrière ; dans certains modes de réalisation, la construction viscoélastique comprend au moins deux couches barrière dont la composition diffère de celle d'au moins une couche viscoélastique, les deux couches barrière, ou plus, étant fixées auxdites première et seconde matrices de résine. Dans certains modes de réalisation, la ou les couches barrière peuvent être sensiblement imperméables aux solvants organiques, et/ou sensiblement imperméables à l'eau et/ou sensiblement imperméables aux gaz.
