摘要：

A combustion model of glycidyl azide polymer (GAP) is presented. Linear burning rate and temperature profile measurements of model samples led us to the conclusion that linear burning rate is controlled by N-2 liberation process below the pressure exponent break point (2.3 MPa). Further, scanning electron microscope (SEM) photographs and Fourier transform infrared (FTIR) spectra of quenched samples by rapid depressurization of the combustor show that the N-2 liberation process is strongly limited to the melt layer at the combustion surface and the profile of the heat release rate is probably delta -function like. This fact enables the application of an asymptotic analysis to this phenomenon.
