Abstract
The present paper focus on a numerical simulation failure probability prediction of cylindrical part of type III CNG storage vessel under pressure with end effect, which has a thin metallic envelope, called liner who is coated by a filament winding composite layers. First, a sensitivity analysis contribution was performed in order to identify the influence of the different parameters as: materials properties, geometry, manufacturing and loading, on the reliability of the Liner-Composite structure studied. Finally, the failure probability of this kind of storage structure is estimated by Monte Carlo method. In order to predict the main parameters which can be the origin of failure, we opted to a high number of drawings, N=104. The results obtained show that liner thickness and internal pressure have large significant influence on the security of the composite vessels type III in relation to the others manufacturing parameters.
