The effect of accelerated aging on the performance of urethane coated Kevlar used in RAM air decelerators
GAIL TUTT, ROBERT PHUNG, LOUIS VITA, ARTHUR FIORELLINI, Walter D. Koenig · 1991
Ram air decelerators made from several types of polyurethane coated KEVLAR were conditioned at elevated temperature and humidity over a sixteen week period. The conditioned decelerators were then subjected to both traditional and newly developed tests, and the results analyzed. Due to experimental limitations insufficient data was obtained for adequately predicting the long term performance of these materials. However, recommendations are made for future use of adhesion, blocking, hydrostatic resistance, hot inflation, and wind tunnel testing.
