Title (EN) PRE-IMPREGNATED FIBRE-REINFORCED COMPOSITE MATERIAL AND MANUFACTURED ARTICLE OBTAINED BY FORMING AND COMPLETE CURING OF SAID PRE-IMPREGNATED FIBRE- REINFORCED COMPOSITE MATERIAL
(FR) MATÉRIAU COMPOSITE RENFORCÉ PAR DES FIBRES PRÉ-IMPRÉGNÉES ET ARTICLE MANUFACTURÉ OBTENU PAR FORMAGE ET DURCISSEMENT COMPLET DUDIT MATÉRIAU COMPOSITE RENFORCÉ PAR DES FIBRES PRÉ-IMPRÉGNÉES
Abstract:
(EN) The invention relates to a pre-impregnated fibre- reinforced composite material in laminar form, obtained impregnating a fibrous mass with a polymeric binder composition and intended to be subjected to successive forming and complete curing operations to produce a fibre-reinforced composite material. The polymeric binder composition comprises one or more resins chosen in the group consisting of siloxane resins and silsesquioxane resins, and can optionally comprise one or more organic resins. The polymeric binder composition appears as a liquid with viscosity between 55000 and 10000 mPas at temperatures between 50°C and 70°C. The polymeric binder composition forms a polymeric binder matrix, not cross-linked or only partially cross-linked, that fills the interstices of the fibrous mass. The invention also relates to a method for making said pre- impregnated fibre-reinforced composite material in laminar form. The invention also relates to a manufactured article obtained by hot forming and complete curing of the aforesaid pre-impregnated fibre- reinforced composite material, as well as a method for making said manufactured article.
(FR) La présente invention concerne un matériau composite renforcé par des fibres pré-imprégnées sous forme laminaire, obtenu par imprégnation d'une masse fibreuse avec une composition de liant polymère et destiné à être soumis à des opérations successives de formage et de durcissement complet afin de produire un matériau composite renforcé par des fibres. La composition de liant polymère comprend une ou plusieurs résines choisies dans un groupe constitué des résines de siloxane et des résines de silsesquioxane et pouvant éventuellement comprendre une ou plusieurs résines organiques. La composition de liant polymère apparaît sous la forme d'un liquide ayant une viscosité comprise entre 55000 et 10000 mPas à des températures comprises entre 50 °C et 70 °C. La composition de liant polymère forme une matrice de liant polymère, non réticulée ou seulement partiellement réticulée, qui remplit les interstices de la masse fibreuse. La présente invention concerne également un procédé de fabrication dudit matériau composite renforcé par des fibres pré-imprégnées sous forme laminaire. La présente invention concerne également un article manufacturé obtenu par formage à chaud et durcissement complet du matériau composite renforcé par des fibres pré-imprégnées mentionné ci-dessus, ainsi qu'un procédé de fabrication dudit article manufacturé.
