A study was conducted to determine the relative effectiveness of Al-foil-on-fabric, Al deposit on fabric, white organic coatings on fabric and bleached white goods for use as protective barriers against intense thermal radiation. The temperature-time histories of human skin and an epoxy-resin skin simulant contiguous to the irradiated cloth indicate that for a given radiant exposure the temperature rise of the backing behind the fabric with the Al foil coating is one-fifth that behind the bleached-goods group whereas the temperature rise of the backing behind the fabrics with the Al deposit and those with plastic coatings is one-third that behind the bleached-goods group of cloths. Except for the bleached-goods group, which showed a high thermal resistance, but also a high transmittance, it may be expected that these heat-reflecting textiles will serve as effective barriers to intense thermal radiation provided they are separated from the background, in which case the backing will be damaged only negligibly before they are destroyed.
