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. •Type-IV composite pressure vessels (CPVs) are popular lightweight solutions for high-pressure gas storage.•The hoop stress distribution of an anisotropic fiber-reinforced Type-IV CPV is crucial.•Winding schemes affect CPVs hoop strength when exposed to internal pressure.•Multi-angle winding can benefit structural integrity and performance for specific applications.
