Recently the use of intumescents that interact with flame retardant fibres during the application of heat to form a novel char structure showing unusually high flame and heat resistance has been reported [1]. The interactive pyrolytic mecha nisms of both components creates a char-bonded structure that is unusually resistant to oxidation. This paper extends the previous work to include flame retardant cotton; it studies the evidence of this interaction by thermo-analytical and scanning electron microscopic studies. The char formation characteristics and oxidative resistance ofthe composites have been studied by mass loss calorimetry at heat flux rates in the range 25-75 kW.m-2.
