Failure pressures of composite cylinders with a plastic liner

The present experimental study deals with the temperature and the stacking sequence effects on the response of the composite cylinders under the internal pressure. GRP composite cylinders were manufactured by using E-glass fibers and epoxy resin and tested for the close-ended condition. Test specimens were manufactured of four antisymmetric layers with [theta degrees/-theta degrees/theta degrees/-theta degrees](2) orientations with five different winding angles over a plastic liner. Filament wound cylinders were subjected to internal pressure at four different temperatures such as 2 degrees C, 25 degrees C, 60 degrees C, and 80 degrees C. The aim of this study was to investigate the thermal effect on the failure pressures of filament wound cylindrical composites according to different fiber orientation angles subjected to internal pressure loading at various temperatures. The results show that the orientation angle and the temperature have significant effects on the failure pressures of the composite cylinders.
