This paper focuses on the issue of fire growth on composite materials beyond the region immediately subjected to an ignition source. Suppression of this growth is one of the key issues in realizing the safe usage of composite structural materials. A vinyl ester/glass composite was tested in the form

β¦ Synopsis
Three existing models of upward flame spread were tested against intermediate-scale experiments on a vinyl ester/glass composite. Characterization of rate of heat release per unit area, needed as input to the models, was obtained at external radiant fluxes below the minimum for ignition by adaptation of a method due to Kulkarni. There are several limitations on the accuracy of the material characterization when applied to composites. Each of the flame spread models has definite limitations as well. Nevertheless, all three models produced predictions of spread behavior in sufficiently quantitative agreement with the experiments that they should prove useful for engineering analyses of flame spread potential.

## A BS TRA C T There appears to be a fundamental difference between a twodimensional theory of upward flame spread on thick solids based on a fractional power, such as 3, between flame length and heat release rate and one based on a proportionality between them. Simple models based on the former
## Abstract Simulation results, obtained by means of application of an enthalpyβbased pyrolysis model, are presented. The ultimate focus concerns the potential of the model to be used in flame spread simulations. As an example we discuss vertically upward flame spread over a charring material in a
