The effects of repeated transverse impact load on the burst pressure of composite pressure vessel

The present experimental study deals with the repeated transverse impact effect on the burst pressure of composite pressure vessels. Filament winding method is used to produce the vessels. Glass fiber reinforced (GFR) vessels are manufactured by using E-glass and epoxy resin. Composite pressure vessel was manufactured from fibers oriented [+55 degrees/-55 degrees/+55 degrees/-55](2s) and the impact energies were chosen as 10, 15, 20, 25,30 J for empty vessel during the impact tests. In addition, 10, 15, 20, 25J for water filled conditions at 25 and 70 degrees C. The transverse impact load was applied in single and three times repeated form. The results show that when the impact load and water temperature increases, the burst pressure decreases. (C) 2014 Elsevier Ltd. All rights reserved
