Abstract

Multilayer composite material comprising specific polycarbonate compositions as matrix material The present invention relates to a composite material comprising one or more fibre layers composed of a fibre material and an aromatic polycarbonate-based matrix material. The fibre layer(s) is/are embedded in the matrix material. The present invention further relates to a process for producing these fibre composite materials, to multilayer composite materials comprising several layers of fibre composite material, and to the use of the composite materials for production of components or housing components or housings, and to the components, housing components or housings themselves.
