本研究调查了使用整体式混合膨胀型隔热层（垫）在暴露于火灾或热源时为核心纤维增强聚酯复合材料结构完整性提供表面保护。在50 kW/m2的恒定热通量下，对由含有硅酸盐纤维、可膨胀石墨和某些情况下由有机基质粘合在一起的硼硅酸盐玻璃的膨胀垫/织物保护的玻璃纤维增强复合材料的防火性能进行了评估。绝缘织物的厚度，以及对所得的混合复合材料的可燃性的化学组成的影响进行了评估。没有任何表面保护的玻璃纤维增强聚酯（GRP）复合材料与由绝缘织物保护的芯复合材料相比，具有相对较高的点火时间和峰值热释放速率值。热谱图表示的混合复合材料的反面上的温度随时间的变化时，暴露于恒定的热通量表明，包括膨胀型表面屏障内的核心玻璃钢复合材料的延迟的温度增量的结果。版权所有© 2009约翰威利父子有限公司。
This study investigates the use of integral, hybrid intumescent thermal barriers (mats) to provide surface protection to the core fibre‐reinforced polyester composite structural integrity when exposed to a fire or heat source. Glass fibre‐reinforced composites protected by intumescent mats/fabrics containing silicate fibres, expandable graphite and in some cases borosilicate glass bounded together by an organic matrix have been evaluated for fire performance under a constant heat flux of 50kW/m2. The effect of insulative fabric thickness as well as chemical composition on the flammability of the resultant hybrid composites is evaluated. Glass fibre‐reinforced polyester (GRP) composites without any surface protection have a relatively higher time‐to‐ignition and peak heat release rate values when compared with core composites protected by insulative fabrics. Thermograms representing the variation of temperature on the reverse side of the hybrid composites with time when exposed to a constant heat flux show that the inclusion of intumescent surface barriers results in retarded temperature increments within the core GRP composites.
