Modeling of flame spread behaviors of carbon fiber reinforced plastics

Abstract

The preheat zone of CFRP was much longer than that of PMMA. It indicates that the carbon fibers conductively transferred heat forward. And the solid-phase heat transfer is important for modeling of flame spread of CFRP. However, the conventional flame spread models, only involve the gas-phase heat transfer from flame. Probably, those models would not be able to cover materials such as CFRP. This study proposes a novel flame spread model which considers the solid-phase heat transfer. And to validate the developed model, the calculated flame spread rates of CFRP are compared with the measured ones.
