    (Elsevier, 2022) Azeem, Mohammad; Ya, Hamdan Haji; Alam, Mohammad Azad; Kumar, Mukesh; Stabla, Pawel; Smolnicki, Michal; Gemi, Lokman
    The filament winding (FW) technology is one of the emerging manufacturing practices with a high degree of excellence and automation that has revolutionized gas storage and transportation doctrine. Various pressure vessels have evolved in the last few decades, from metal to fiber-reinforced tanks, primarily for weight savings and high-pressure ratings; advantageously, Type 4 composite pressure vessels (CPVs) can affect fuel gas tanks' weight savings to 75% compared to metallic vessels. As a result, composite pipelines and CPV manufacturing through FW technology have proliferated. Though many design and manufacturing challenges are associated with various process factors involved in winding technology, careful considerations are needed to create a reliable product. Therefore, it is essential to comprehend the various process parameters, their combined effects, and the associated challenges while designing and fabricating filament-wound structures. This article reviews the FW technique's utility, its evolution, various process parameters, and the CPVs as an emerging contender for high-pressure gas and cryo fluid storage. In addition, different optimization techniques, numerical analysis strategies, and challenges are summarized with related disputes and suggestions.

    Influence of winding angles on hoop stress in composite pressure vessels: Finite element analysis
    (Elsevier, 2024) Azeem, Mohammad; Ya, Hamdan H.; Alam, Mohammad Azad; Kumar, Mukesh; Sajid, Zubair; Gohari, Soheil; Maziz, Ammar
    Various pressure vessels from Type I to Type IV are used to store hydrogen and compressed natural gas (CNG) at high pressures. The polymeric liner in Type IV composite pressure vessels (CPVs) does not share the load, unlike those with metallic liners (Type III); hence, the composite layers share the entire load. The winding angles play a crucial role in tailoring the pressure-bearing properties of CPVs. This study investigated the effect of fiber winding angles on the hoop stress in Type IV CPVs using finite element (FE) analysis, and the advantage of multi -angle winding was realized. Stress analysis is vital to ensure that the vessel can withstand the intended operating conditions without undergoing failure. A series of finite element analyses (FEA) was carried out using the Abaqus FE simulation software to study the behavior of an anisotropic fiber-reinforced CPV with varied winding schemes. A stress analysis was performed, and various winding schemes were compared for different cases. The hoop stress in various configurations was documented to assess and compare various winding configurations.
