Composite pressure vessels are lightweight structures mainly used in automotive applications, because of their ability to store gaseous energy fuels at high pressures. This study focuses on the development of design methods to reduce the chances of leakage or burst failure in type-4 cylinders for storage of compressed natural gas (CNG). The design of the pressure vessel is methodized using finite element analysis yielding the least chances of fiber slippage or breakage. The manufacturing technology is optimized to enhance the product performance and reduce the chances of defects during winding. The design methodology is validated by comparing the experimental burst pressure with the theoretical value. The resultant is a high-performing, lightweight, low-cost vessel that is safe for the storage of CNG for onboard applications.

复合压力容器是轻型结构，主要用于汽车应用，因为它们能够在高压下存储气态能源燃料。这项研究专注于设计方法的开发，以减少用于存储压缩天然气（CNG）的4型气缸泄漏或爆裂的机会。压力容器的设计采用有限元分析方法，使纤维打滑或断裂的机会最小。优化了制造技术，以提高产品性能并减少缠绕过程中出现缺陷的机会。通过将实验爆破压力与理论值进行比较来验证设计方法。结果是一种高性能，轻便，低成本的容器，可以安全地存储船上使用的CNG。
