酚醛树脂/玻璃纤维型飞机货舱衬板复合材料火灾危险性评价

应用锥形量热仪和烟密度箱测试分析飞机货舱衬板在不同火灾环境下的燃烧特性，结合锥形量热仪实验数据对玻璃纤维/酚醛树脂复合材料的火灾危险性进行评价。结果表明：不同热辐射强度对货舱衬板的影响有区别，热辐射强度越大，热分解越快，点燃时间越短，热释放速率峰值越大，最大峰值为98.5 kW/m2，最大总热释放量为7.7 MJ/m2，总生烟量最大为0.8 m2，质量损失也就越多；在同一热辐射强度下，A320货舱衬板复合材料在有焰燃烧情况下的比光密度为2.39，而在无焰燃烧情况下最大比光密度为16.06；结合CONE测试数据计算出FGI、FPI、THRI和TSPI四项火灾危险性评价指标，得出FPI与热辐射强度成负相关关系，FGI、THRI和TSPI均与热辐射强度成正相关关系。

Fire hazard evaluation of phenolic resin/glass fiber aircraft cargo lining composite material

Cone calorimeter and smoke density box were used to test and analyze the combustion characteristics of aircraft cargo compartment liners in different fire environments, and the fire hazard of glass fiber/phenolic resin composites was evaluated based on the experimental data of cone calorimeter. The results show that different heat radiation intensities have different effects on cargo tank linings. The greater the heat radiation intensity, the faster the thermal decomposition, the shorter the ignition time, and the greater the peak heat release rate. The maximum peak value is 98.5 kW/m2, and the maximum total heat release is 7.7 MJ/m2, and the maximum total smoke production is 0.8 m2, and the mass loss is greater. Under the same heat radiation intensity, the specific optical density of the A320 cargo tank lining composite material under flaming combustion is 2.39, and the maximum specific optical density is 16.06 in the case of flameless combustion. Combined with the CONE test data, four fire risk evaluation indicators, FGI, FPI, THRI and TSPI are calculated. FPI is inversely related to the thermal radiation intensity, and FGI, THRI and TSPI are all positive related to the thermal radiation intensity.
