模块化玻璃纤维增强聚合物 (GFRP) 多细胞结构是使用拉挤 GFRP 盒部分通过粘合剂结合在两个 GFRP 平板之间形成的。三种类型的防火板，即玻璃镁（GM）板、石膏灰泥（GP）板和轻质硅酸钙（CS）板，用螺钉安装在下部GFRP平板的外表面。然后将组合样本的下表面暴露于火中。对由不同防火板组装而成的 GFRP 多孔样本的热响应进行了测量和比较分析，并与观察到的损坏模式相关联。研究发现，防火板有效地缓解了 GFRP 组件中产生的温度变化，从而提高了这些结构组件的防火隔离性能。 GM板的防火隔热性能最好，受火90分钟后，上层GFRP平板外表面（未受火表面）最高温度低于120℃。此外，还评估并强调了多单元组件的空腔和端盖配置对传热的影响。
Modular glass fibre reinforced polymer (GFRP) multicellular structures were formed using pultruded GFRP box sections incorporated between two GFRP flat panels by adhesive bonding. Three types of fire resistant panels, namely glass magnesium (GM) board, gypsum plaster (GP) board and lightweight calcium silicate (CS) board, were installed at the outer face of the lower GFRP flat panel using screws. The lower surfaces of the built-up specimens were then exposed to fire. The thermal responses of the GFRP multicellular specimens assembled with different fire resistant panels were measured and comparatively analysed, in association with the damage patterns observed. It was found that the fire resistant panels effectively mitigated the temperature progressions developed in the GFRP components, thereby improving the fire insulation performance of those structural assemblies. The GM board provided the best fire insulation performance, with the highest temperature at the outer face of the upper GFRP flat panel (the surface unexposed to fire) being less than 120 °C after 90 min of fire exposure. Further, the effects of cavities and end closure configurations of the multicellular assemblies on the heat transfer were evaluated and highlighted.
