There is a risk that FW composite pressure vessel is exposed to high temperatures by a fire accident of Fuel Cell Vehicles. This paper aimed to develop a method of estimating the burst pressure from the temperature and time that FW composite pressure vessel is exposed. Vessels (Type-3, volume 2.1L, Maximum pressure 19.4MPa) were heated in the atmosphere five different thermal history (Room temperature, 473K-1hour, 573K-30min, 573K-1hour, 573K-2hour). Burst tests at room temperature, ultrasonic testing, cross-sectional observation of CFRP and stress analysis were conducted for FW composite pressure vessels.
