“…Here, the netting analysis material model is used to post-treat the results of the membrane structural model. This combination of models is used in the literature for preliminary design of the stacking sequence in the cylinder [5] or to design the optimal dome shape considering only a couple of orientations ±θ [18]. Here, we show here that it is particularly useful to anticipate possible critical points in the dome design for any number of orientations ±θ i .…”

“…The typical way to present netting analysis is in terms of static quantities only [7,5]. As such, it may seem inappropriate to present this approach in the section about material models, but this apparent contradiction will be resolved later.…”

“…This confirms the common observation that the dome is indeed the critical zone in composite pressure vessels, and it highlights the importance of this simple tool to anticipate the position and value of the maximum stress due to membrane loadings. A solution to reduce the fiber stresses in the dome without significant oversizing of the cylinder is to add doily layers in specific positions in the dome [5]. This is rather easy to manufacture by laser assisted tape placement in the case of thermoplastic matrix composites.…”

“…Type V vessels, which do not include a liner, are currently at the research stage [4]. Type IV pressure vessels are particularly interesting for the transportation industry, for example for the storage of high-pressure hydrogen in fuel cell vehicles [5,6]. The mechanical response of type IV composite pressure vessels to an applied internal pressure is determined by two levels of geometrical features:…”

The mechanical response of pressure vessels to an applied internal pressure is essentially controlled by a few key parameters, related both to the overall geometry of the structure and to the orientations and thicknesses of the composite layers. The role of each parameter, and the way they interact to determine the structural response, can be apprehended at a very early design stage by using simple material and structural models, which enable to explore a wide range of designs with minimal computational cost. More complex models can then be called into play to predict the detailed structural response, including crucial information such as the burst pressure and failure mode. This paper discusses a hierarchy of models with increasing levels of details and complexity, which are useful to gain increasing insight on the pressure vessel response all along the design process.

“…These stresses affect the mechanical properties of the manufactured composite structures, essentially, as evidenced in works [ 1 , 2 , 3 , 4 , 5 , 6 ]. In particular, this problem is strongly observed in the manufacturing of composite materials and their cylindrical structures commonly used in the oil and gas industry [ 7 , 8 ], the automotive sector including pressure vessels [ 9 , 10 , 11 ] as well as in the aerospace industry [ 12 , 13 ]. In recent decades a significant interest in the matter can be observed.…”

The Mechanical Investigation of Filament-Wound CFRP Structures Subjected to Different Cooling Rates in Terms of Compressive Loading and Residual Stresses—An Experimental Approach

et al. 2021

Although cooling at ambient temperature is widely used and is said to be safe and convenient, faster cooling may have an influence not only on the time of the manufacturing process but also on the mechanical response, especially the residual stress. The study aimed to investigate the influence of the cooling rate after curing on the mechanical response of filament-wound thick-walled carbon fiber reinforced polymer (CFRP) rings. Three cooling rates were taking into consideration: cooling with the oven, at room temperature, and in the water at 20 °C. The splitting method was used to examine the residual strains. In the radial compression test, the mechanical response was investigated between the rings with different cooling regimes. The FEM analysis of the compression test in elastic range was also performed. Both the splitting method and the radial compression test showed no significant difference in the mechanical response of the CFRP rings. The presented results showed that the fast-cooling rate slightly decreases the mechanical performance of the filament-wound rings.
