Abstract：The burning characteristics of aircraft cabin materials must be well characterized to enable prevention and early detection of in-flight fires. This study characterized two aircraft cabin materials for the seat and the interior wall at Kangding Airport in Sichuan Province where the atmospheric pressure is 61.0 kPa and at Guanghan where the pressure is 96.0 kPa. The experiments measured the mass loss ratio, smoke density, smoke components, and flame shape to examine the effect of low pressure on the burning characteristics. The results show that both materials have higher mass loss ratios at 96.0 kPa than at 61.0 kPa. However, the smoke density increases rapidly and changes more at 61.0 kPa. The smoke density peaks for both materials at 61.0 kPa are twice those at 96.0 kPa. Although the times to reach the peak concentrations of CO and CO2 are nearly the same, the concentrations of CO and CO2 are quite different for the two pressures.
