Abstract

Composite materials in specific modulus, specific strength and corrosion resistant properties are better than the metal materials. But as the composite materials thermal conductivity worse than metal, the speed of composite materials temperature rises more than metal. Then it is very necessary that the discussion of the composite material heat-resistant properties and flame retardant performance whether could meet the metal material performance requirements. This paper applied Fluent software to discuss shrinkage ratio aircraft fuel tank experiment method which simulate aircraft fuel tank top plate to accept the sun heat radiation 1 hour. During this time, the test plate center temperature, fuel surface temperature and fuel steam temperature. Comparing with Fluent simulation results and FAA test data, the results are basically the same trend, but there are still some residuals. According to FAA data correction calculation method, simulated a larger percentage or full size composite fuel tank fire experiment provides calculation method.
