A1
Abstract:
Provided are: pellets that make it possible to provide a molded product that contains a polycarbonate resin and recycled carbon fibers, that has a mechanical strength close to the case in which the same quantity of virgin carbon fibers are contained therein, and that exhibits excellent flame resistance; a molded product; and a pellet manufacturing method. The pellets are formed from a composition containing 5-65 parts by mass of the recycled carbon fibers, which are the heated product of a carbon fiber-reinforced resin, and 0.05-25 parts by mass of a non-metallic salt-based flame retardant per 100 parts by mass of the polycarbonate resin, which has a terminal hydroxyl group content of 150-800 ppm.
