- Abstract
- The need for nonflammable fibrous materials intended for incorporation into life support systems for aircrew protection from fires along with the state-of-the-art of such materials is discussed. Fabrics are evaluated on the basis of heat transmission from direct flame contact as well as for flammability. Five characteristics have been found to affect fabric heat transfer: fiber thermal stability, thickness, weave or knit pattern, air permeability and bulk density. PBI is the only fiber in woven form that has provided the combined thermal and comfort characteristics required for use in flight suits.
