Beschreibung
Zusammenfassung:	A composition that contains a polycarbonate resin and a recycled carbon fiber, and demonstrates mechanical strength which is close to that of a case where the virgin carbon fiber is blended. The composition contains 100 parts by mass of a polycarbonate resin having a terminal hydroxy group content of 150 to 800 ppm; and 5 to 65 parts by mass of a recycled carbon fiber which is a heated product of a carbon fiber-reinforced resin. A pellet formed of the composition. A molded article formed of the composition. A method for producing the composition. The method includes feeding to an extruder 100 parts by mass of a polycarbonate resin having a terminal hydroxy group content of 150 to 800 ppm, and 5 to 65 parts by mass of a recycled carbon fiber which is a heated product of a carbon fiber-reinforced resin; and melt kneading the extruded polycarbonate resin.
