“…As already known from investigations that compared with the strain criterion, the stress criterion is not appropriate with respect to predicting burst pressure, which would cause the relative large error. 28 In this study, based on the maximum strain criterion, the burst pressure was determined by the fracture strain of hoop layers. According to the numerical results of finite element analysis, the maximum circumferential strain varied with the internal pressure is shown in Figure 5.…”

Composite material high-pressure storage vessel has been increasingly applied in the hydrogen storage industry. This study aims to establish parametric analysis of fiber wound composite vessel and investigate the stress distribution, failure mechanism as well as the burst strength. Based on the maximum strain criterion and Tsai-Wu failure criterion, the burst strength of the vessel and the failure mechanism of the cylinder segment were evaluated and studied. The stresses of the cylinder were much higher than those of the dome. The cylindrical part of the vessel is its weakest area. Matrix failure initiated at the spiral wound layer, then the accumulation of matrix failure resulted in the stiffness becoming degraded and hence fiber failure happened on the hoop wound layers. The fiber failure leaded to the ultimate failure of the vessel. The wound scheme of the outer layers also plays an important role on the load-bearing ability of the vessel. The burst strength of vessel with case-A wound was 122 MPa, while it was 91 MPa for case-B wound, about 25.4% decrease. The numerical results were compared with the burst mode studied in experiments on composite vessels and a good agreement was obtained. This study provides a theoretical foundation for safe design and utilization of composite material high-pressure vessel in the fields of hydrogen storage.

“…However, despite its advantages, geodesic winding has limitations due to shape constraints, polar hole radius, and initial winding angle, which can restrict the adjustability and designability of the shell winding pattern. 9,10 According to the reviewed literature, non-geodesic winding can be divided into two categories: those with constant and variable slippage coefficients, commonly used in bends, pressure vessels, and other applications. A curve with a constant slippage coefficient along the fiber path is referred to as a constant slippage coefficient non-geodesic.…”

Previous studies on the design methods of filament winding paths for composite pressure vessels have mainly focused on geodesic and constant slippage coefficient non‐geodesic patterns, neglecting the design of variable slippage coefficients along the fiber path. In this paper, a design method of variable slippage coefficient non‐geodesic filament wound composite pressure vessels is proposed. The study begins by establishing a meridian rotation mapping model and deriving fiber path equations on the shell surface. Subsequently, the fiber paths, curvature characteristics, slippage coefficients, and shell stress responses of the shell under variable geometrical parameters are simulated and analyzed. Next, the winding parameters are optimized while considering bandwidth and stable winding constraints. The optimal winding parameters are determined, and filament winding simulations are conducted on composite pressure vessels. Results demonstrate the feasibility of the proposed method for variable slippage coefficient fiber path winding mode, providing a new and effective filament winding path design approach for composite pressure vessels.Highlights Establishment of meridian rotation mapping model and simulation of shell fiber paths under variable geometric parameters.

“…High-performance carbon fiber reinforced polymer (CFRP) composites have outstanding strength-and stiffness-to-weight ratios, therefore they are traditionally chosen for advanced lightweight applications such as aerostructures, spacecraft, automotive, among others [1][2][3][4]. Among the manufacturing processes available for advanced polymer composites, filament winding (FW) stands out for being able to produce from flat laminates [5] to elbows and curved-surface structures [6][7][8]. The high fiber volume fraction and precision in angle deposition, along with the use of a pre-tensioned and continuous reinforcement are the main features of FW [9].…”
