Fire-Resistance Performance Tests for Floor Structure of Railway car Using Aluminum Porous Sandwich Panel

Abstract

The floor structure of a railway car in one of the main structure of the railway car should support the many things such as chairs, passengers and electronic units which are hung to the structure. One of main functions of the floor structure of the railway car besides the supporting function is fire-resistance performance for fire safety of the railway car. In this study a new type of a floor structure of a railway car adopted an aluminum porous sandwich panel and urethane foam are introduced for weight reduction and easiness of installation, respectively. The fire-resistance performance of the three specimens of the floor structure of a railway car are tested. Two of them are assembled the sandwich aluminum porous panel and the other is assembled a plywood as a supporting floor for the reference test. Urethane foam and glass fiber for of insulation materials are considered.
