The compositions contain, as flameproofing system, a phosphorus/nitrogen component, aluminium hydroxide and at least one synergistic component from the series comprising organic nitrogen compounds and polyalcohols or derivatives thereof, where the phosphorus/nitrogen component may be ammonium polyphosphate. To produce the flame-resistant mouldings, a curable synthetic resin is mixed with a flameproofing system comprising a phosphorus/nitrogen component, aluminium hydroxide and at least one synergistic component from the series comprising organic nitrogen compounds, polyalcohols and derivatives thereof. The mixture is processed by wet pressing at pressures of from 3 to 10 bar either at room temperature (from 20 to 60 DEG C) or at elevated temperature (from 80 to 150 DEG C). Finally, synthetic resin mats can be produced from the mixture at pressures of from 50 to 150 bar and temperatures of from 140 to 160 DEG C.
