Fire resistance evaluation of a train carbody made of composite material by large scale tests

This paper explains fire resistance tests of a train carbody made of composite materials. In this study, fire performance tests using specimens and a large scale mock-up were performed to evaluate the fire safety of the composite train carbody. From the specimen tests, it was seen that the interior panels met the fire safety for the flame propagation, toxicity and smoke density performance. In addition, the fire resistance of the composites carbody was verified by the larger scale tests under the real fire accident scenario. From the results, both the surface temperature of the interior and the composite carbody were lower than the ignition temperature.
