characteristics of the thermal decomposition of composite cylinder has been
thoroughly investigated when it is exposed to a engulfing fire. In the
computations, one-dimensional heat transfer model and the Arrhenius type
kinetic equations are incorporated to construct the robust framework for
predicting the surface recession profile of the cylinder wall. An experiment was conducted to measure in surface
temperatures and internal
pressure of a commercial composite cylinder that was exposed to engulfing fire. The cylinder used in the
experiment is a Type ¥² NGV composite cylinder which was manufactured
with epoxy/carbon fiber by the
hoop and helical winding methods. The cylinder liner is made of aluminum alloy, and glass bulb type TPRD is
built in the cylinder valve. An engulfing fire test was
conducted with kerosene on a NGV composite cylinder. Surface recession depth profiles were
calculated using surface
temperature data
obtained from the experimental
results, and they were compared with the time dependent pressure change.
