摘要： 为了探究民航客机货舱侧壁板材料的燃烧特性，采用锥形量热仪研究其在火灾环境下的燃烧特性，并且采用两种评价指标对材料的火灾危险性进行评估。试验结果表明：材料的热释放速率曲线只有1个增长峰，热辐射强度从20 kW/m2增至50 kW/m2时，材料燃烧的热释放速率峰值从98.64 kW/m2增至201.46 kW/m2，质量损失随着辐射强度的增加而增加；燃烧过程中CO和CO2生成量随辐射强度的增加而增加；通过燃烧点燃模型得到侧壁板材料的理论临界热流为10.20 kW/m2；热辐射值的变化对飞机货舱侧壁板的火灾危险指标影响较大。

Abstract: In order to explore the combustion characteristics of the side panel material of civil aircraft cargo hold, cone calorimeter was used to study its combustion characteristics under fire environments, and two evaluation indexes were used to evaluate the fire hazard of the material. The experimental results show that the heat release rate curve of the material has only one growth peak. When the heat radiation intensity increases from 20 kW/m2 to 50 kW/m2, the heat release rate peak of the material combustion increases from 98.64 kW/m2 to 201.46 kW/m2, and the mass loss increases with the increase of radiation intensity. CO and CO2 production increased with the increase of radiation intensity during combustion; through the combustion ignition model, the theoretical critical heat flux of the sidewall material is 10.20 kW/m2; the change of thermal radiation value has a great influence on the fire risk index of aircraft cargo compartment sidewall plate.
