Title (EN) PRE-IMPREGNATED FIBRE-REINFORCED COMPOSITE MATERIAL AND FIBRE-REINFORCED COMPOSITE CERAMIC MATERIAL, OBTAINED BY FORMING AND SUBSEQUENT PYROLYSIS OF SAID PRE-IMPREGNATED MATERIAL
(FR) MATÉRIAU COMPOSITE RENFORCÉ PAR DES FIBRES PRÉ-IMPRÉGNÉ ET MATÉRIAU CÉRAMIQUE COMPOSITE RENFORCÉ PAR DES FIBRES, OBTENU PAR FORMAGE ET PYROLYSE ULTÉRIEURE DUDIT MATÉRIAU PRÉ-IMPRÉGNÉ
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 pyrolysis operations to produce a fibre- reinforced composite ceramic material. The polymeric binder composition is based on one or more resins chosen from the group consisting of siloxane resins and silsesquioxane resins, and can optionally comprise one or more organic resins. The polymeric binder composition is a liquid with viscosity between 55000 and 10000 mPas at temperatures between 50°C and 70°C. The polymeric binder composition forms a polymeric binding 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 further relates to a fibre-reinforced composite ceramic material, obtained by forming and subsequent pyrolysis of a pre-impregnated fibre- reinforced composite material, as well as a method for making said material.
(FR) L'invention concerne un matériau composite renforcé par des fibres pré-imprégné sous forme laminaire, obtenu par imprégnation d'une masse fibreuse avec une composition de liant polymère et destiné à être soumis à des opérations de formage et de pyrolyse successives pour produire un matériau céramique composite renforcé par des fibres. La composition de liant polymère est à base d'une ou de plusieurs résines choisies dans le groupe constitué de résines de siloxane et de résines de silsesquioxane et peut éventuellement comprendre une ou plusieurs résines organiques. La composition de liant polymère est un liquide ayant une viscosité comprise entre 55 000 et 10 000 mPa à des températures comprises entre 50 °C et 70 °C. La composition de liant polymère forme une matrice de liaison polymère, non réticulée ou seulement partiellement réticulée qui remplit les interstices de la masse fibreuse. L'invention concerne également un procédé de fabrication dudit matériau composite renforcé par des fibres pré-imprégné sous forme laminaire. L'invention concerne en outre un matériau céramique composite renforcé par des fibres, obtenu par formage et pyrolyse ultérieure d'un matériau composite renforcé par des fibres pré-imprégné, ainsi qu'un procédé de fabrication dudit matériau.
