Adhesive bonded joints of fiber-reinforced polymer structural components provide countless benefits; these include great strength and large hardness-to-weight ratios, good fatigue and corrosion resistance, and high energy absorption capability, all of which make them more influential in comparison with other types of fasteners. In this study, the effect of various contents of graphene nanoparticle (GNP) in the epoxy adhesive on the shear and flexural behaviors of glass fiber-reinforced polymer plates (GFRP) bonded joints are investigated. Based on the weight content of epoxy graphene, nanoparticles were added by 0.1, 0.2, 0.3, 0.4, and 0.5 wt.%. GFRP were used as adherents. Failure mechanisms were analyzed by taking photos over the front and rear sides of the samples after tests. The obtained results showed that 0.3 wt.% graphene nanoparticle addition exhibiting the better load transferring between adherents had 145% improvements in shear strength. Furthermore, the samples containing 0.2 wt.% GNP resulted in an increase in flexural strength by 100%.

纤维增强的聚合物结构部件的胶粘接头提供了无数的好处。这些优点包括高强度和大的硬度/重量比，良好的抗疲劳和耐腐蚀性能以及高的能量吸收能力，所有这些使得它们与其他类型的紧固件相比具有更大的影响力。在这项研究中，研究了环氧胶粘剂中不同含量的石墨烯纳米颗粒（GNP）对玻璃纤维增​​强聚合物板（GFRP）粘结接头的剪切和弯曲行为的影响。基于环氧石墨烯的重量含量，以0.1、0.2、0.3、0.4和0.5重量％添加纳米颗粒。GFRP被用作黏附剂。在测试后，通过在样品的正面和背面拍摄照片来分析失效机理。所得结果表明0.3重量％。表现出更好的粘合剂之间负载转移的％石墨烯纳米颗粒添加使剪切强度提高了145％。此外，含有0.2重量％GNP的样品导致抗弯强度提高了100％。
