Accelerated Weathering of Polyamides, Aromatic Polyamides, and Polybenzimidazole Fabrics

Abstract

Parachute pack fabrics utilized in personnel decelerators are subjected to extensive solar radiation during in flight missions and related ground handling situations. Parachute pack replacements during the service life of a parachute results in additional costs, unnecessary and excessive out of commission time, and the requirement for larger inventories. The data presented covers the work accomplished on an internal program to study the reaction and resistance of various types of actual and candidate parachute pack fabrics to UV exposure. As expected Type 330 nylon was the most UV RESISTANT MATERIAL EVALUATED. PBI-II and dyed Nomex had approximately the same percentage retention of breaking and tear strength but were not equal to UV resistant nylon.
