Chopped carbon fibers, comprising a set of chopped carbon fibers impregnated with a sizing agent, the short fiber bundle pieces constituting the set, having an average weight per unit length of 1.7 to 4 mg/mm in the fiber length direction and a coefficient of variation of 30 to 60% in the distribution of weights per unit length in the fiber length direction. The chopped carbon fibers can be used for molding a carbon fiber reinforced composite product.

Fibres de carbone coupées, comprenant une série de fibres de carbone coupées imprégnées d'une solution de collage. Les morceaux de fibres coupées qui forment la série ont un poids moyen par longueur d'unité de 1,7 à 4 mg/mm dans le sens de la longueur de la fibre et un coefficient de variation de 30 à 60 % dans la distribution des poids par longueur d'unité dans le sens de la longueur de la fibre. Les fibres de carbone coupées peuvent être utilisées pour mouler un produit composite renforcé de fibres de carbone.
