Composite Pressure Vessels

The main target of the present study is to preserve the structural integrity of the composite pressure vessels (PVs) used in the seawater reverse osmosis (SWRO) desalination plants under internal pressure loading when moisture effects are taken into consideration. Different composite material lay-ups and fiber orientations are considered. In each case, the optimum safe thickness of the PV is found based on the appropriate failure criterion. The PVs are made of carbon/epoxy C/E IM7/977-3 with (±θ)ns lay-up. For verification purposes, PVs made from stainless steel SST 316L and carbon/epoxy C/E AS4/3501-6 are considered and their available results are compared with the predictions of the MATLAB code developed in this study. The study consists of three main cases. The first case considered the PVs materials SST 316L steel and C/E AS4/3501-6 carbon/epoxy composite, without moisturizing effect, with the purpose to verify the results of the developed MATLAB code by comparing with results from the available literature. The second case is concerned with the composite material C/E IM7/977-3, without moisture effects, while the third case included moisture effects on the same material (C/E IM7/977-3). The optimum angles found for C/E AS4/3501-6 is (±55.1)ns and for C/E IM7/977-3 with and without moisture are (±55.8)ns and (±54.0)ns, respectively. The best weight saving of the composite PV, when compared to the steel PV, reached 95.2%.

Composite Pressure Vessels

AbstractA new method to design composite pressure vessels under strain and strength constraints using lattice structures is described. A graphical analysis is presented to find the optimum geometrical parameters of the rib for given fiber orientations. Minimum pressure vessel mass is determined from active execution of two constraints. Composite lattice structures are suggested as a new way of strain suppression among the commonly used methods such as (1) addition of extra plies, (2) use of composite material with a higher stiffness and (3) replacement of the circumferential layer with a second helical layer made of different materials. The experimental and analytical results of application of the method indicate that the vessel covered with composite lattice structures presented considerable weight savings with respect to traditional stiffened vessels.
