CA 2634229
The invention relates to glass fibres coated with a sizing composition comprising (in weight %): between 25 and 90 % of at least one filming agent; between 3 and 25 % of at least one coupling agent; and between 2 and 18 % of nanoparticules. The invention also relates to a sizing composition which can coat said fibres, to the method for the production thereof, and to composites containing such fibres. The inventive glass fibres have a high resistance to ageing in a damp medium.
L'invention concerne des fils de verre revêtus d'une composition d'ensimage qui comprend (en % en poids) : - 25 à 90 % d'au moins un agent filmogène - 3 à 25 % d'au moins un agent de couplage - 2 à 18 % de nanoparticules. Elle concerne également une composition d'ensimage apte à revêtir lesdits fils, son procédé d'obtention et les composites incorporant de tels fils. Les fils de verre de l'invention présentent une résistance élevée au vieillissement en milieu humide.
