Surprisingly, the molding composition additionally exhibits an improvement in flame retardancy. The invention relates in particular to flame-retardant, thermoplastic molding compositions filled with glass fibers, and to the production and use thereof. The property profile is, surprisingly, independent of the degree of interaction of the filler with the polycarbonate matrix.
