The Effect of High Heating Rate on the Pyrolysis of Polymeric and Composite Materials,

Abstract

The pyrolysis of a carbon/phenolic sample has been investigated as a function of heating rate (from 0.167 K/sec to 30000 K/sec) and has been modeled by assuming two mechanisms are operating: a process with a low energy of activation which dominates at low heating rates and a process with a high energy of activation which becomes important at high heating rates. Kinetic and modeling parameters for sample pyrolysis at each heating rate are reported and have been used to accurately reconstruct the sample thermographs. In addition, the high heating rate instrument/method is described in detail. 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. (jes)
