    Abstract: Sheet-like reinforced materials consisting of A. a core layer comprising a sheet-like textile structure, preferably a glass fiber mat, B. a plastic matrix composed of a nylon which has been polymerized under alkaline conditions and penetrates both the core layer and the surface layer of layers, are produced batchwise by the RIM method or continuously on a double-belt press by impregnating the sheet-line textile structure and the foam sheets with a lactam melt and polymerizing the latter. The reinforced material can be used for the production of finished articles having a satisfactory surface, for example for the automotive or aircraft industry.

    Abstract: The invention relates to a process for preparing self-releasing, compact or cellular moulded bodies optionally containing reinforcing agents and made of polyisocyanate polyaddition products by reacting a) organic and/or modified organic polyisocyanates with b) at least one compound with at least two reactive hydrogen atoms and a molecular weight of 500 to 9,000 and optionally c) chain extension and/or cross-linking agents in the presence of d) alkyl and/or alkenyl succinic acid monoamides, -monoamides, poly(alkyl succinic acid)- and/or poly(alkenyl succinic acid)-polyamides, -polyimides, -monoamide monoimides, -polyamide imides, -amide polyimides and- polyamide polyimides or mixtures thereof as internal mould release agents, and also in the presence or absence of e) catalysts, f) blowing agents, g) reinforcing agents, h) auxiliary agents, in an open or closed moulding tool, optionally under compression. The invention also relates to the use of alkyl- and/or alkenyl succinic acid amides and/or imides (d) as internal mould release agents for the preparation of moulded bodies made of polyisocyanate polyaddition products.
