Abstract

This paper explains fire safety tests of a hybrid composite train carbody with carbon/epoxy sandwich bodyshell and stainless steel underframe. In this study, a large scale mock-up was used to evaluate the fire safety of the composite train carbody. The test was conducted to the bare composite carbody mock-up without interior facilities and the fully equipped one. Tile fire propagation and temperature distribution of the carbon/epoxy bodyshell and the glass phenol interior panels was evaluated under the real fire accident scenario. The test scenario was based on the DaeGu subway fire accident. From the tests, both the surface temperature of the interiors and the composite bodyshell wore lower than tile ignition temperature. In addition, the fire spread along the surface of the interiors and bodyshell was not occurred.

본 논문에서는 탄소/에폭시 면재와 알루미늄 허니콤 심재를 갖는 바디와 스테인레스 언더프레임을 갖는 철도차량 차체에 대한 화재안전성평가 시험을 수행하였다. 이를 위해 실규모 차체를 제작하고 이를 이용하여 시험을 수행하였다. 시험에 적용된 차체는 내장재가 포함되지 않은 차체와 내장재를 포함을 차체 두가지를 이용하였으며 시험조건은 대구지하철 화재사고 시나리오에 근거하여 설정하였다. 시험결과 차체 및 내장재 표면의 최대온도는 각각의 발화온도에 미치지 못함을 확인하였고, 차체 내부에 화염전파도 발생하지 않았다.
