Hydrogen, as a zero-emission fuel, produces only water when used in fuel cells, making it a vital contributor to reducing greenhouse gas emissions across industries like transportation, energy, and manufacturing. Efficient hydrogen storage requires lightweight, high-strength vessels capable of withstanding high pressures to ensure the safe and reliable delivery of clean energy for various applications. Type V composite pressure vessels (CPVs) have emerged as a preferred solution due to their superior properties, thus this study aims to predict the performance of a Type V CPV by developing its numerical model and calculating numerical burst pressure (NBP). For the validation of the numerical model, a Hydraulic Burst Pressure test is conducted to determine the experimental burst pressure (EBP). The comparative study between NBP and EBP shows that the numerical model provides an accurate prediction of the vessel's performance under pressure, including the identification of failure locations. These findings highlight the potential of the numerical model to streamline the development process, reduce costs, and accelerate the production of CPVs that are manufactured by prepreg hand layup process (PHLP), using carbon fiber/epoxy resin prepreg material.
氢气作为一种零排放燃料,在燃料电池中使用时仅产生水,这使其成为交通运输、能源和制造业等行业减少温室气体排放的重要贡献者。高效的氢气储存需要能够承受高压的轻质、高强度容器,以确保为各种应用安全可靠地输送清洁能源。V型复合压力容器(CPV)因其卓越性能已成为首选解决方案,因此本研究旨在通过建立其数值模型并计算数值爆破压力(NBP)来预测V型CPV的性能。为了验证数值模型,进行了液压爆破压力试验以确定实验爆破压力(EBP)。NBP与EBP的对比研究表明,该数值模型能够准确预测容器在压力下的性能,包括确定失效位置。这些发现凸显了数值模型在简化开发过程、降低成本以及加速采用碳纤维/环氧树脂预浸料通过预浸料手工铺层工艺(PHLP)制造的CPV生产方面的潜力。
