Multilayer composite design material having special polycarbonate compositions as matrix material

A fibre composite material comprising at least one layer of fibre material embedded into an aromatic polycarbonate-based composition, wherein the composition comprises

• A) 60% by weight to 85% by weight of aromatic polycarbonate,
• B) 2% by weight to 20% by weight of white pigment,
• C) 0% to 2.5% by weight of colourants other than components B),
• D.1) 0% to 12% by weight of one or more oligomeric phosphates of the general formula (5)
• in which
• R1, R2, R3 and R4 are each independently a C1- to C8-alkyl radical, in each case optionally halogenated and in each case branched or unbranched, and/or C5- to C6-cycloalkyl radical, C6- to C20-aryl radical or C7- to C12-aralkyl radical, in each case optionally substituted by branched or unbranched alkyl and/or halogen,
• n is independently 0 or 1,
• q is an integer from 0 to 30 and
• X is a mono- or polycyclic aromatic radical having 6 to 30 carbon atoms or a linear or branched aliphatic radical having 2 to 30 carbon atoms, each of which may be substituted or unsubstituted, and bridged or unbridged,
• D.2) 4% by weight to 12% by weight of one or more cyclic phosphazenes of the formula (1)
• where
• R is the same or different at each instance and is an amine radical, an in each case optionally halogenated C1- to C8-alkyl radical, C1- to C8-alkoxy radical, in each case optionally alkyl- and/or halogen-substituted C5- to C6-cycloalkyl radical, in each case optionally alkyl- and/or halogen- and/or hydroxyl-substituted C6- to C20-aryloxy radical, in each case optionally alkyl- and/or halogen-substituted C7- to C12-aralkyl radical or a halogen radical or an OH radical,
• k is an integer from 1 to 10.
