The invention relates to glass fiber-reinforced polycarbonate compositions and molding materials comprising A) from 10 to 85 parts by weight, preferably from 30 to 80 parts by weight, especially from 40 to 70 parts by weight, of polycarbonate, polyestercarbonate or a mixture thereof, B) from 10 to 50 parts by weight, preferably from 15 to 40 parts by weight, especially from 20 to 35 parts by weight, of rubber-free vinyl copolymer, C) from 5 to 50 parts by weight, preferably 7 to 35 parts by weight, especially from 8 to 25 parts by weight, of a sized glass fiber, the size comprising an epoxy polymer, D) from 0 to 2 parts by weight, preferably from 0 to I part by weight, of rubber-modified graft polymers, the composition more preferably being free of rubber-modified graft polymers, and E) from 0 to 10 parts by weight, preferably from 0.01 to 5 parts by weight, especially from 0.1 to 3 parts by weight, of conventional polymer additives, the composition being free of rubber-modified polymers other than component D, and the sum of components A+ B + C + D + E being normalized to 100 parts by weight, which are notable compared to the prior art for high stiffness, high flowability, high processing stability, good chemical resistance and good ageing stability with respect to influences of light and heat, and to the use of the compositions for producing shaped bodies, and to shaped bodies comprising the inventive compositions. |
