Zusammenfassung:	A thermoplastic composite material including: a) from 65% to 95% by weight of at least one reactive semicrystalline polyamide prepolymer with an average molecular mass Mn of less than or equal to 8000 g/mol and having a volume-mean diameter D50 of the reactive semicrystalline polyamide prepolymer powder particles ranging from 10 to 300 μm, b) from 5% to 35% by weight of at least one flame retardant chosen from an at least partially meltable flame retardant in powder form and a non-meltable flame retardant in premilled powder form with a volume-mean diameter D50 of from 1 to 50 μm, and c) from 0 to 2% by weight of at least one meltable or non-meltable additive with a volume-mean diameter D50 of from 1 to 50 μm if it is non-meltable and in powder form.
