lass fiber reinforced PA6 (GFPA6) is an important engineering plastic for its excellent mechanical properties and chemical resistance. However, the development and application of the composites were limited due to their flammability. Meanwhile, some halogen-containing additives could cause environmental problems. Therefore, the development of halogen-free flame retarded GFPA6 composites is demanded. Metal salts of alkylphosphinic acid have been found to be particularly effective in polyesters and polyamides. Both condensed and gas-phase actions caused by the organic phosphinate salts have been well investigated in some researches. In our previous study, aluminum hypophosphite (AP) was proved an effective flame retardant for GFPA6. And the aim of present research is to combine the AP and an S-containing flame retardant (MEDS) to flame retardant GFPA6 composites. The composites will be investigated for the contributions to possible fire hazards using cone calorimetry and thermal gravimetric analysis/infrared spectrometry technique. Furthermore, the thermal degradation behavior and fire performance of these composites were studied, and the flame retardancy mechanism was discussed.
