Heat Resistant and Nonflammable Materials
Abstract
The tensile properties of spun-yarn, flight-suit weight HT-4, Durette, Nomex I, Kynol, cotton, nylon and polyester fabrics have been measured during exposure to bilateral radiant heat fluxes in the range 0.2 to 0.9 cal/sq cm/sec. Specially designed test equipment allows testing at times as short as a few seconds after initiation of exposure. All of the fabrics tested lost at least 50% of their strength in the first 6 seconds of exposure at flux levels of 0.4 cal/sq cm/sec and at least 75% of their strength after 6 seconds at 0.7 cal/ sq cm/sec and above. Of those fabrics tested, Ht-4 provides the greatest degree of protection and polyester provides the least protection against a high heat flux. Studies were also made of launderability of HT-4 fabric, abrasion of Kevlar webbing, weaving of BBB fabric, and other analyses requested by AFML.
