The resin composition contains polyamide 66 and aramid fiber. The polyamide 66 has a number average molecular weight of 34000 to 60000. The number average molecular weight is measured by gel permeation chromatography using hexafluoroisopropanol (HFIP) as a solvent and poly (methyl methacrylate) (PMMA) as a reference material. The content of the aramid fiber is 5 to 25 mass %.

Abstract: Carbodiimide is added to a molten polyamide resin so as to provide resin pellets. The percentage of residual unreacted carbodiimide to each resin pellet is 0.03% to 0.33% by mass. Manufacturing molded articles using the resin pellets achieves both of an improvement in mechanical strength and an increase in wear resistance, and reduces property variations among the molded articles.
