Residual failure pressures and fatigue life of filament-wound composite pipes subjected to lateral impact

This study presents the effect of impact energy on the static failure pressures, and fatigue life of composite pipes. The specimens manufactured have inner diameter 100 mm and length 400 mm. Impact tests were realized at three different energy levels 5.0, 7.5, and 10.0 J. Force-deflection curves were plotted. Impacted and non-impacted specimens were subjected to internal pressure statically and dynamically to obtain failure pressure and fatigue life of the composite pipe, respectively. Results indicate that leakage and eruption pressures for static test decrease and perspiration, leakage, and eruption cycles decrease by lateral impact.
