Abstract:

Air Force flight suits made from PBI and Nomex fabrics were exposed to JP-4 liquid fuel fires to evaluate the thermal protection qualities offered to flight personnel. The two fabrics were compared on the basis of flammability, mechanical, and comfort characteristics. Thermal protection provided by the two materials was based on the mean difference in percent body area damaged for sixty flight suits when exposed to a JP-4 fuel fire. PBI allowed twenty-one point five percent less damage when compared to Nomex. PBI fabric in addition to providing thermal protection, has been proven in a full scale wear test to be the most comfortable flight suit fabric tested by the Air Force Operational Commands.
