The application of natural fiber-reinforced composites is gaining interest in the automotive, aerospace, construction, and marine fields due to its advantages of being environmentally friendly and lightweight, having a low cost, and having a lower energy consumption during production. The incorporation of natural fibers with glass fiber hybrid composites may lead to some engineering and industrial applications. In this study, abaca/glass fiber composites were prepared using the vacuum-assisted resin transfer method (VARTM). The effect of different lamination stacking sequences of abaca-glass fibers on the tensile, flexural, and impact properties was evaluated. The morphological failure behavior of the fractured-tensile property was evaluated by 3D X-ray Computed Tomography and Scanning Electron Microscopy (SEM). The results of mechanical properties were mainly dependent on the volume fraction of abaca fibers, glass fibers, and the arrangement of stacking sequences in the laminates. The higher volume fraction of abaca fiber resulted in a decrease in mechanical properties causing fiber fracture, resin cracking, and fiber pullout due to poor bonding between the fibers and the matrix. The addition of glass woven roving in the composites increased the mechanical properties despite the occurrence of severe delamination between the abaca-strand mat glass fiber.
由于天然纤维增强复合材料具有环保、轻质、成本低以及生产过程中能耗较低等优点，其在汽车、航空航天、建筑和船舶领域的应用正受到越来越多的关注。将天然纤维与玻璃纤维混合复合材料相结合可能会带来一些工程和工业应用。在本研究中，采用真空辅助树脂传递模塑法（VARTM）制备了蕉麻/玻璃纤维复合材料。评估了蕉麻-玻璃纤维不同层压堆叠顺序对拉伸、弯曲和冲击性能的影响。通过三维X射线计算机断层扫描和扫描电子显微镜（SEM）对断裂拉伸性能的形态失效行为进行了评估。力学性能的结果主要取决于蕉麻纤维、玻璃纤维的体积分数以及层压板中堆叠顺序的排列。蕉麻纤维体积分数较高导致力学性能下降，由于纤维与基体之间粘结不良，造成纤维断裂、树脂开裂和纤维拔出。尽管在蕉麻股垫玻璃纤维之间出现了严重的分层，但在复合材料中添加玻璃纤维粗纱仍提高了力学性能。
