Failure analysis of biocomposite sandwich pipe under internal pressure – Application for high pressure gas transportation pipelines MEDGAZ

In this paper, analytical and 3D numerical models are developed to investigate the mechanical behavior of sandwich pipe under internal pressure loading. The suggested provide an exact solution for stresses, strains displacement on pipe, which is made epoxy material core layer reinforced materials with alternate-ply skin layers. aim analysis evaluate potential applications jute pineapple leaf fiber (PALF) bio-fibers in order replace glass synthetic fibers generally employed pipes. subject, a failure was using TSAI-WU criterion. results stress, strain distribution through thickness presented models. comparison between both show very good agreement. increase rigidity biocomposite reduce gap compared sandwich, gradual reinforcing numbers chosen, permitted best behavior. ultimate safety factors obtained by increasing layers significant composite transportation pipelines, especially based PALF/epoxy.
