The effect of the geometry of metallic fibers on the mechanical response of aluminum fiber-reinforced composite adhesive joints was studied experimentally. Moreover, a combination of multi-walled carbon nanotubes and aluminum fibers was used for reinforcing the composite adhesive joints. Different geometries for the aluminum fibers including straight, twisted and spring-shaped with different pitch lengths were considered. The results indicated that the composite adhesive joints reinforced with a combination of multi-walled carbon nanotubes and aluminum fibers experienced the highest improvement of 171% in the strength compared to the unreinforced specimen. It was found out that the aluminum fiber geometry can significantly influence the adhesive joint behavior. Incorporating the twisted aluminum fibers into the adhesive layer increased, while the spring-shaped fibers decreased the strength of the composite adhesive joints compared to the straight aluminum fibers. The fracture surfaces of the composite adhesive joints were analyzed using scanning electron microscope.

实验研究了金属纤维的几何形状对铝纤维增强复合胶粘接头力学响应的影响。此外，使用多壁碳纳米管和铝纤维的组合来增强复合粘合剂接头。考虑了铝纤维的不同几何形状，包括具有不同节距长度的直形，扭曲形和弹簧形。结果表明，与未增强的试样相比，用多壁碳纳米管和铝纤维组合增强的复合粘合剂接头的强度最高提高了171％。发现铝纤维的几何形状可以显着影响粘合接头的行为。将加捻的铝纤维掺入粘合剂层的数量增加了，弹簧形纤维与铝制直纤维相比降低了复合粘合接头的强度。使用扫描电子显微镜分析复合粘合接头的断裂表面。
