Abstract In this work, aluminum diethylphosphonate (ADP), in company with melamine polyphosphate (MPP) or melamine cyanurate (MCA), was used to flame retard glass fiber reinforced polyamide 6 composites (PA6/GF). The research results showed that compared with MCA, the combination of MPP and ADP can play a better synergistic and flame retardant effect. When the total amount of flame retardant was 10wt% and the mass ratio of ADP and MPP was 8∶1, the limiting oxygen index (LOI) value of PA6/GF/ADP∶MPP(8∶1) composite was 29.7%, while the vertical combustion grade reached UL-94 V-1 rating. Compared with PA6/GF/ADP composites, the peak heat release rate (pk-HRR) and total heat release capacity (THR) of PA6/GF/ADP∶MPP(8∶1) composite decreased to 307.6 kW/m2 and 154.6 MJ/m2, respectively. Meanwhile, the carbon residue of the composite in cone calorimetry test was as high as 40.6%, which indicated that MPP can improve the flame retardant effect of the flame retardant system in the condensed phase. In addition, the introduction of MPP was beneficial to improve the tensile strength of the composites. Compared with PA6/GF/ADP composites, the tensile strength of PA6/GF/ADP∶MPP(8∶1) increased by 17.6%.
