Abstract (EN):
A new generation of composite pressure vessels for large scale market applications has been studied in this work. The vessels consist on a thermoplastic liner wrapped with a filament winding glass fibre reinforced polymer matrix structure. A high density polyethylene (HDPE) was selected as liner and a thermosetting resin was used as matrices in the glass reinforced filament wound laminate. The Abaqus 6.5.1 FEM package was used to predict the mechanical behaviour of pressure vessels according to the requirements of the EN 13923:2005 standard. The composite laminate and thermoplastic liner failures were predicted, considering the elasto-plastic behaviour of the HDPE liner and the laminae properties, respectively. Finally, prototype pressure vessels were produced in the defined conditions to be submitted to pressure tests. The comparison between the FEM simulations and experimental results are discussed in the present paper.
