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.
This experimental study discusses the effects of the tube diameter and the impact energy level on the impact and compression after impact behaviors of [AE55] 3 filament-wound glass/epoxy composite tubes. Four different tube diameters were selected as 50, 75, 100, and 150 mm. The composite tubes were subjected to various impact energy levels, 15, 20, and 25 J, using an instrumented impact testing machine at room temperature. Impacted and nonimpacted samples were subjected to axial compression tests. Results indicated that both specimen diameter and impact energy highly affect the impact response and compression-after impact strength of composite tubes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
