Abstract

In this study, nine composite overwrapped pressure vessel (COPV) models (type IV) have been developed to analyze their burst pressure performance using the ultimate tensile strength (UTS) from experiment and the von Mises stress profile from finite element ABAQUS simulation. The four-layer jute-reinforced PV shows almost five times lower burst pressure than Kevlar-based PV, indicating the inherent vulnerability of using pure jute. However, for the hybrid jute/Kevlar alternate combination, JKJK shows strength improvement over a jute PV by almost two times. Other jute hybrids with glass and aluminum foil show very comparable performance when compared to jute PV. Both yarn and braided-type jute fiber exhibit similar operating conditions, indicating that the preparation type of jute fiber is invariant to pressure performance. However, COPVs woven with 90° cross-oriented jute fibers are found to have the most degraded strength, highlighting that fiber orientation remains an important optimization factor in designing PVs with hybrid composite wraps.

凯夫拉/黄麻纤维及混合复合材料压力容器的数值模拟

在本研究中，开发了九个复合材料外覆压力容器（COPV）模型（IV型），利用实验中的极限抗拉强度（UTS）和有限元ABAQUS模拟中的von Mises应力分布来分析其爆破压力性能。四层黄麻增强PV的爆裂压力几乎是Kevlar基PV的五倍，这表明使用纯黄麻的固有脆弱性。然而，对于混合黄麻/凯夫拉交替组合，JKJK显示出比黄麻PV的强度提高了近两倍。与黄麻PV相比，其他具有玻璃和铝箔的黄麻杂化物表现出非常相似的性能。纱线和编织型黄麻纤维都表现出相似的操作条件，表明黄麻纤维的制备类型对压力性能是不变的。然而，发现用90°交叉定向黄麻纤维编织的COPV的强度下降幅度最大，这突出表明纤维定向仍然是设计具有混合复合材料包裹的PV的重要优化因素。
