Mock-Up Scale Fire Test based on Arson Scenario for a Composite body Railway Passenger Coach

초록

Two cases of mock-up scale fire tests with composite body railway passenger coach were conducted. First test was conducted with 1.8 liters of gasoline for the epoxy-carbon FRP car body without interiors. Second test was conducted with 4.0 liters of gasoline for the whole car including interiors of phenol composite sandwich wall panel, rubber flooring cover and four sets of passenger seats. The fire scenario was selected based on the possible arson case for the car body and inner materials. Fire performance and the temperature distribution of inner space and the material temperature of car body and phenol sandwich were investigated. The temperature of the epoxy-carbon composite body goes up to 138 → at first test. The temperature of the phenol sandwich panel goes up to 300 → while the temperature of inner space reaches 795 → at second test. The margins from the measured temperature of the car body and wall panel to the ignition temperature of them kept over 200 → during the test. Figs. 1~3 show the status of fire tests and the damaged inside view of the coach. Computer simulation with FDS supports the results of these tests. The limitation of the fire test under uncontrolled outdoor is reviewed based on two test results. The data of these tests will be helpful for selecting the materials and fire safety management of composite body railway passenger train.
