A composition for producing a fiber-reinforced polyurethane composite product including: (I) a reactive mixture of: (a) at least one polyisocyanate; (b) at least one polyol, and (c) at least one tin (IV)-based catalyst; and (II) at least one fibrous material; and a fiber-reinforced polyurethane composite product produced from the above composition. L'invention concerne une composition pour la production d'un produit composite de polyuréthane renforcé par des fibres comprenant : (I) un mélange réactif de : (a) au moins un polyisocyanate ; (b) au moins un polyol, et (c) au moins un catalyseur à base d'étain (IV) ; et (II) au moins un matériau fibreux ; et un produit composite de polyuréthane renforcé par des fibres produit à partir de la composition ci-dessus.
