- Abstract
- The thermal degradation is modeled of a one-dimensional disk of poly(methyl methacrylate) (PMMA)
with and without the dispersion of carbon nanotubes exposed to a fire-level heat flux. The description of
the chief transport processes (conductive, convective and radiative heat transfer, convective mass
transport) is combined with a one-step finite-rate reaction for polymer decomposition resulting in
surface ablation (absence of nanotubes) or the formation of network-structured continuous layer of
carbon nanotubes. Good agreement is obtained between the predicted and measured mass loss rates for
the two cases. The presence of nanotubes reduces the peak in the mass loss rate and increases the
conversion time, owing to the insulating effects of the surface layer and the much larger surface reradiation
losses. The effects of flame retardance are enhanced by increasing the growth rate and/or
the thickness of the surface layer. (literal)
