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.

Fiber composite material, use therefor, and method for the production thereof

The present invention relates to flame-retardant, impact-modified polycarbonate (PC) compositions and molding compositions which have good mechanical properties, good resistance to chemicals and high hydrolytic stability. The present application additionally relates to the use of the compositions in the production of molded articles, and to molded articles produced from the compositions.

Flame-retardant polycarbonate molding materials V

The present invention relates to flame resistant molding compositions comprising polycarbonates and graft polymers which, in addition to good flow properties, exhibit good (notched) impact strength and high chemical resistance with a UL94V-0 classification at 1.5 mm. These molding compositions are particularly suitable for thin-walled housing parts in the electrical and electronics sector.

Flame-retardant PC/ABS compositions having good impact strength, flowability and chemical resistance

The present disclosure relates to impact-modified polycarbonate compositions which comprise a graft polymer containing silicone/acrylate composite rubber as the graft base, wherein the content of silicone rubber is 65-95 wt. % (based on the graft base), talc having a dvalue (also called 'top cut') of less than 20 &#x3bc;m and phosphorus-containing flame retardant, the use of the polycarbonate compositions for the production of shaped articles and the shaped articles themselves. The compositions and moulding compositions according to the disclosure have an optimum combination of good flameproofing, good resistance to chemicals and hydrolysis and good mechanical properties (i.e. in particular a high E modulus and high notched impact strength a).

Flame retardant impact-modified polycarbonate compositions

The present invention relates to flame-resistant moulding compositions of polycarbonates and graft polymers which, in addition to good flow properties, have very good mechanical properties and a particularly good, trouble-free surface. These moulding compositions are suitable in particular for injection moulding uses for mouldings with thin wall thicknesses and high-gloss surfaces. The thermoplastic moulding compositions according to the invention comprise A) 65.0 to 82.0 parts by wt. of at least one aromatic polycarbonate, B) 4.0 to 11.0 parts by wt. of at least one graft polymer, C) 14.0 to 24.0 parts by wt. of at least one phosphorus-containing flameproofing agent, wherein the sum of the parts by weight of components A to C adds up to 100 parts by weight and the total content of the polymer which is formed from the grafting monomers or is added in the free form and is not bonded chemically to the graft base is less than 2.0 wt. %, based on the total moulding composition.
