Abstract: Disclosed is a glass fiber-reinforced polycarbonate flame-retardant resin composition which comprises (A) 50 to 75% by weight of polycarbonate having a melt index of 22 g/10 min or more (300° C., 1.2 kg), (B) 3 to 15% by weight of a rubber-modified styrene-based graft copolymer, (C) 3 to 10% by weight of a bulk copolymer of an aromatic vinyl compound and a vinyl cyan compound, (D) 1 to 10% by weight of an ethylene acrylate-based copolymer, (E) 10 to 25% by weight of glass fiber, and (F) 5 to 20% by weight of an aromatic phosphate ester-based compound, and thus advantageously exhibits superior flowability, flame retardancy, hardness, impact resistance and appearance qualities.
