A composite fiber, which includes: 100 parts by weight of a wholly aromatic polyamide mainly including structural units of the following formulae (A) and (B): -NH-Ar1-NH- (A) -OC-Ar2-CO- (B) where in the formulae (A) and (B) , Ar1 and Ar2 each independently represent a bivalent aromatic group having 6 to 20 carbon atoms; and 0.01 to 100 parts by weight of carbon nanotubes with an average diameter of 300 nm or less, and an average aspect ratio of 5.0 or more, characterized in that the carbon nanotubes are oriented in the fiber axis direction. It is excellent in mechanical characteristics.

L'invention concerne des fibres composites caractérisées en ce qu'elles contiennent 100 parties en poids d'un polyamide entièrement aromatique composé essentiellement d'unités structurales représentées par les formules générales (A) -NH-Ar?1¿-NH- et (B) -OC-Ar?2¿-Co- (dans lesquelles Ar?1¿ et Ar?2¿ représentent chacun indépendamment un groupe aromatique divalent C¿6-20?), et 0,01 à 100 parties en poids de nanotubes en carbone ayant un diamètre moyen de 300 nm ou plus petit et un rapport de forme moyen de 5,0 ou plus, et en ce que les nanotubes en carbone ont été orientés dans le sens de l'axe des fibres. Les fibres composites présentent d'excellentes propriétés mécaniques.
