Carbon nanofibers (CNFs) can be considered a kind of carbon nanotubes (CNTs). This paper describes about dispersion of CNFs in the polypropyrene matrix composites and mechanical properties of specimens fabricated by injection molding. Dispersion of CNFs in the composites is quantified by the residual cluster rate and the maximum cluster size. The residual cluster rate is almost constant when the kneading time is 5min. or more, but the maximum cluster size slightly decreases with the kneading time. Young's modulus of the composites fabricated on the optimal conditions obtained from the relations between the mechanical properties and the kneading conditions was 1.4 times higher than that of neat PP when the CNF content was 10wt%.
