The Effect of High Heating Rate on the Pyrolysis of Carbon/Phenolic Composites
Abstract
The effect of heating rate on the pyrolysis of polymeric and composite materials has been extensively studied using thermal gravimetric analysis (TGA) techniques. Material behavior under conditions of high heating rate (>10000 K/sec) has recently become of great interest because of the need to predict high performance material behavior in harsh thermal environments and to accurately model the interaction of directed energy with polymeric and composite materials, especially with respect to material blowoff resulting form the generation of internal gas pressures. In this work, we report on the effect of bulk heating rates (ranging from 0.167 K/min to 30000 K/sec) on the pyrolysis of a carbon/phenolic composite material. The high heating rates have been achieved using a resistance heating system. Kinetic parameters describing the pyrolysis have been obtained using a modified Friedman approach. Keywords: Thermographs.
