Title: Development of NGV high pressure storage technologies. Brunswick Composites Project No. 19072. Final report, November 1992-December 1994

Technical Report ·
OSTI ID:63756

The objective of this project was to evaluate All-Composite cylinders relative to their damage toughness and to determine if acoustic emission (AE) testing might be a viable nondestructive evaluation (NDE) technique for evaluating performance. Damage testing included drop test, pendulum impact, and machined flaws. A total of nine cylinders were intentionally damaged, and the cycle and burst test performance of these cylinders was compared to the performance of nine undamaged cylinders. The test results revealed that, with one exception, the damage on these units did not significantly affect cycle life or burst pressure performance. A total of thirty-five cylinders were subjected to AE testing. This testing indicated that AE was not a useful technique for predicting cylinder stress-rupture life; however, AE did show promise as a means of detecting localized cylinder damage.
