In the present work, some materials that are commonly used in the construction industry were studied with regard to their thermal degradation characteristics and combustion attributes. These included façade materials for pre-fabricated houses, such as the layers of cross-laminated timber (CLT) and the inner core of aluminium composite panels (ACPs). The relevant investigations were carried out by employing thermo-gravimetric analysis (TGA) and pyrolysis combustion flow calorimetry (PCFC). The Arrhenius parameters and the associated calorimetric quantities, i.e., heat release rates, temperature to the peak heat release rate, heats of combustion, heat release capacities, and char yields, were also evaluated. These parameters showed that CLT is more fire retarded than the polymeric internal core of ACP façade materials. Furthermore, some valuable correlations among the various test quantities were found. For instance, a good correlation exists between the general profiles of the thermograms obtained through TGA runs and the heat release rate (HRR) traces from PCFC measurements. Depending on the nature of the materials, the char yields measured by PCFC can be 4-20 times higher than the ones obtained through TGA.
在本研究中，对建筑行业常用的一些材料的热降解特性和燃烧属性进行了研究。这些材料包括预制房屋的外墙材料，如交叉层压木材（CLT）层和铝塑复合板（ACP）的内芯。相关研究通过热重分析（TGA）和热解燃烧流动量热法（PCFC）进行。还评估了阿伦尼乌斯参数和相关的量热参数，即热释放速率、热释放速率峰值温度、燃烧热、热释放能力和残炭率。这些参数表明，CLT比ACP外墙材料的聚合物内芯更具阻燃性。此外，还发现了各种测试量之间的一些有价值的相关性。例如，通过TGA运行获得的热重曲线的一般轮廓与PCFC测量的热释放速率（HRR）曲线之间存在良好的相关性。根据材料的性质，PCFC测量的残炭率可能比通过TGA获得的残炭率高4至20倍。
