Abstract
The present invention provides a reinforced polycarbonate resin composition having all of excellent strength, impact resistance, heat resistance, flame retardancy and thermal stability. A reinforced polycarbonate resin composition which contains 100 parts by weight of a resin composition composed of (A) 50 to 95 parts by weight of a polycarbonate resin (component A) and (B) 5 to 50 parts by weight of a fibrous filler (component B) and (C) 2 to 45 parts by weight of a fluororesin (component C-I) or 2 to 45 parts by weight of a fluororesin (component C-II), wherein (I) the fluororesin (component C-I) is a copolymer containing polymerization units respectively represented by general formulae [1] and [2] and has a melting point of 200 to 280° C., and (II) the fluororesin (component C-II) is a copolymer containing polymerization units respectively represented by general formulae [1] and [2], has a melting point of 240 to 300° C., and has a 5% weight loss temperature of 470° C. or higher as measured by TGA (thermal gravimetric analysis).
