In this research, low-melting phosphate (LMP) glasses (G1, G2, G3) were employed as green flame-retardant synergist additives in epoxy (EP)/ammonium polyphosphate (APP) composite. To investigate their performance additives, comprehensive fire tests and characterizations carried out, including limiting oxygen index test, UL-94 vertical burning cone calorimeter real-time temperature detection, X-...
