The report describes the pyrolysis kinetics of nylon 6-6 and phenolic CTL 91-LD, as derived from thermogravimetric analysis data TGA. Individual rate equations and kinetic coefficients for the two polymers are presented and combined to yield a multi-step pyrolysis rate equation for composited nylon phenolic. The derived rate equations are verified by comparing them to thermogravimetric data taken at rates of sample temperature rise varying from 3Cmin to 100Cmin. Weight-loss data for the nylonphenolic composite, during both isothermal pyrolysis and pyrolysis at programmed rates of temperature rise, are accurately correlated by the multistep pyrolysis rate equation.
