Abstract
The application of compressed natural gas (CNG) as a cleaner and more efficient fuel is becoming more and more popular worldwide. However, the challenges associated with CNG storage, especially with high-pressure gas cylinders, require innovation in materials and design to ensure safety and performance. This study focuses on the optimization of Type 4 CNG cylinders using Finite Element Analysis (FEA) to enhance material selection, layer configuration, and production processes. We evaluate various composite materials, including epoxy carbon, epoxy E-glass, Kevlar, T700, and boron, under operating conditions up to 73 MPa. The results indicate that Kevlar and T700 perform better than the other materials, with lower deformations and higher safety margins, making them ideal for high-pressure applications. In order to ensure long-term durability and safety, the study emphasizes the significance of strengthening crucial layers, especially under conditions of intense pressure. Additionally, covered are suggestions for design enhancements and the possibilities of alternate fuels like hydrogen.
