Variation law of combustion performance of glass fiber reinforced epoxy composites under different heat fluxes was studied. Final result shows that the time of epoxy resin composite shortened when increased the heat flux, and the theoretical minimum ignition heat flux obtained by curve fitting of experiment data is 2.1638kW/m2; multiply heat flux increased the heat release rate and complicate the stratified combustion of materials, which making the heat release rate curves more complicated. What is more，multiply the heat flux caused incomplete...
