National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Storage life of parachutes -- long time material degradation.

DE95009576

Publication Date	1995
Personal Author	Ericksen, R. H.; Whinery, L. D.
Page Count	9
Abstract	This study considers the long-time storage of single-use nylon and Kevlar(reg sign) parachutes. The authors present data from a 29-year-old nylon parachute, and nylon and Kevlar(reg sign) test samples stored 14 years under ambient conditions in the absence of sunlight. They compare the results with existing predictions of parachute material degradation and other aging data. X-ray photoelectron spectroscopy analyses were preformed on Nylon and Kevlar(reg sign) fabrics that were degraded by elevated temperature aging. The results suggest that this technique should be further examined as a (open quotes)non-destructive(close quotes) method of detecting degradation.
