Fiber metal laminates (FML) are promising material candidates in several applications such as aerospace, marine, and construction industries due to their high strength, impact resistance, corrosion resistance, and fatigue properties. However, these materials have a negative impact on the environment due to their higher carbon footprint. This problem could be overcome by hybridizing carbon material with natural biodegradable materials. It is assumed that the higher moisture absorption and lower thermal properties of such materials may affect the long-term stability of the FML. Hence, an attempt is made in this work to evaluate their stability potential by investigating the influence of the addition of natural jute fiber in carbon reinforced aluminum laminate (CARALL) on FML and report their physical effect of stacking sequence on dynamic, mechanical, and thermal properties. In addition, the medium-term absorption kinetics of jute fiber hybridized CARALL, that is, carbon-jute reinforced aluminum laminate (CAJRALL) were performed. The results show that the tensile load bearing capacity of all the immersed laminates decreases at the end of 2 weeks of immersion. Further, CAJRALL was found to possess moderate thermal stability by yielding fewer thermal residues on burning. Finally, the outcome of dynamic mechanical analysis of the hybridized FML reveals that they are capable of storing relatively higher elastic and viscous energies under dynamic conditions with increased damping capability when compared to CARALL. From this study, it is worth to point out that hybridization of CARALL with jute fiber plays a pivotal role in improving environmental friendliness with a lower impact on the overall material properties.

混合纤维金属层压板的中期吸收动力学和热稳定性分析及其物理和拉伸性能的实验研究

纤维金属层压板 (FML) 由于其高强度、抗冲击性、耐腐蚀性和疲劳性能，在航空航天、船舶和建筑行业等多种应用中成为有前景的候选材料。然而，这些材料由于其较高的碳足迹而对环境产生负面影响。这个问题可以通过将碳材料与天然可生物降解材料混合来克服。假设此类材料较高的吸湿性和较低的热性能可能会影响 FML 的长期稳定性。因此，这项工作试图通过研究在碳增强铝层压板 (CARALL) 中添加天然黄麻纤维对 FML 的影响来评估其稳定性潜力，并报告其堆叠顺序对动态的物理影响，机械性能和热性能。此外，还进行了黄麻纤维杂化CARALL，即碳黄麻增强铝层压板（CAJRALL）的中期吸收动力学。结果表明，在浸泡 2 周结束时，所有浸泡层压板的拉伸承载能力均下降。此外，通过在燃烧时产生较少的热残留物，发现 CAJRALL 具有中等的热稳定性。最后，混合 FML 的动态力学分析结果表明，与 CARALL 相比，它们能够在动态条件下存储相对较高的弹性和粘性能量，并具有更高的阻尼能力。从这项研究中，
