Abstract
The invention relates to a fibre composite () comprising at least one fibre layer () composed of a fibre material which is embedded in a matrix () based on a thermoplastic, where the composition of the matrix () contains: 60-95 parts by weight of aromatic polycarbonate and/or aromatic polyester carbonate and further additives. The invention further relates to the use of such a fibre composite for a component for a rail vehicle, in particular for a rail vehicle for transporting passengers. The invention further relates to a process for producing a fibre composite, in which a layer structure () of superposed layers is formed from at least one fibre layer () composed of a fibre material and from polymer layers which are composed of at least one polymer film () and are arranged on both sides of the fibre layer () and in which the layer structure () is pressed under applied pressure and the action of heat to form a fibre composite (), where the polymer film () has a composition corresponding to the matrix of the abovementioned fibre composite.
