In this study, different stacking orders of carbon-jute fiber mats were used to fabricate the composites and hybrids. The impact of different stacking orientations on mechanical properties was investigated experimentally. The experimental results were verified by finite element analysis (). In addition, the impact of the fiber orientation on the loading direction was also investigated. Four layers of fabrics were piled to fabricate the composites by hand-layup with the cold press process. A NaCl solution was used to create a corrosive medium (pH 8), and the composites and hybrids were immersed in that medium, and their mechanical properties were compared. In this research, it has been found that the laminates with the stacking sequence of type- () show the best result among other composites. Jute composites where all the fibers are in the loading direction possess a high strain compared with the other composites and hybrids. On the scanning electron microscope () image, delamination, buckling of fiber, fiber pullout, and voids were observed. In addition, the kinetics of the diffusion mechanism were also investigated, and it was found from the experimental results that the composites and hybrids immersed in pH 8 absorbed water via Fickian diffusion.
在本研究中，采用不同堆叠顺序的碳麻纤维毡来制备复合材料和混杂材料。通过实验研究了不同堆叠取向对力学性能的影响。实验结果通过有限元分析进行了验证。此外，还研究了纤维取向对加载方向的影响。通过手工铺层和冷压工艺，将四层织物堆叠起来制备复合材料。使用氯化钠溶液营造一种腐蚀介质（pH值为8），将复合材料和混杂材料浸入该介质中，并比较它们的力学性能。在本研究中发现，具有类型-（）堆叠顺序的层压板在其他复合材料中表现出最佳结果。与其他复合材料和混杂材料相比，所有纤维都沿加载方向排列的麻纤维复合材料具有较高的应变。在扫描电子显微镜（）图像上，观察到分层、纤维屈曲、纤维拔出和孔隙。此外，还研究了扩散机制的动力学，从实验结果发现，浸入pH值为8的复合材料和混杂材料通过菲克扩散吸收水分。
