Abstract

The thermal protective performance of 21 heat-resistant fabrics made with polybenzimidazole (PBI), aromatic polyamide (aramid), and blends of PBI with aramid or with flame-retardant rayon fibres, was evaluated in laboratory tests by using highly-intense exposures to radiant or convective heat sources. The contribution of heat transfer mechanisms to thermal insulation is discussed, as is the degradation behaviour of different materials in high-intensity heating. Variables important in the development of improved fabrics for thermal protective apparel are identified. The absolute heat intensity determines the insulation protection. Thermal thickness and porosity are also important factors. Ounce for ounce, nonwoven constructions provide better thermal protection than knitted or woven structures.
