Abstrakti

In this work, the stress and strain levels of composite overwrapped pressure vessels and composite tube were evaluated, through an accurate numerical modelling based on finite element method (FEM). It was developed the models of the COPV and tubes with three aluminum liner thickness. Initially, the stress and displacement of the composite layers overwrapping the liner was analyzed and graphically represented. The parametric modelling for study the structural relationship between COPV and pipes were made by three new concepts developed in this work, liner stress and liner strain share fraction and thickness ratio. The results showed representative results at lower pressures, e.g. at 70 bar, where a composite tube can parametrically represent a COPV.
