摘要：

The paper is devoted to the discussion of the possibility of predicting the rate of flame spread (ROS) over glass-fiber-reinforced epoxy resin (GFRER) in an opposed of N2/O2 mixture using three-dimensional numerical simulation in Fire Dynamics Simulator and the simplified solution for thermally thin fuels. In this study, ROS were experimentally obtained for 1.9 mm thick GFRERs based on ED-20 resin. The calibration of the exact solution formula modification is grounded in previous findings from GFRER studies on flame propagation rate. It was found that a simplified consideration of a complex composite material as a homogeneous pyrolyzed fuel in the model is applicable for a satisfactory prediction of the flame spread velocity. The ROS obtained from the Fire Dynamics Simulator modeling exceeds the measured values for downward cases; however, it more accurately represents the concentration trend compared to the simple formula. The obtained data can be used to develop and test more complex models of composite materials combustion.
