The flame-retardant glass fiber(GF) reinforced polyamide(PA)6 composites were prepared by twin-screw extruder, and the glow wire ignition temperature, comparative tracking index, flame-retardant and mechanical properties were studied. The results show that the glow wire ignition temperature and compara-tive tracking index of the flame-retardant PA 6/GF composites(2.0 mm thickness) can reach 850 ℃,425 V respectively, the flame resistance of the composites(1.6 mm thickness) reaches level UL94 V-0, and the flame-retardant PA 6/GF composites have good mechanical properties when the formula is as follows: PA 6 is 32.0 phr, the nitrogen and phosphorus flame retardant is 20.0 phr, brominated polystyrene is 10.6 phr, antimony compound is 3.4 phr, GF is 23.0 phr, barium sulfate is 7.0 phr and the plasticizer is 3.0 phr.
