Abstract

In this paper, the effect of each method consists of a new adhesive layup method of neat adhesive and nanocomposite layer, and simple bonded (SB) joint was proposed in single-lap joints (SLJ). The graphene nanoparticles (GNPs) were added to Araldite 2011 adhesive, and steel 304 was selected as adherends. Two types of graphene (types I and II) were used in nanocomposite construction, that their main differences were in the characteristics of GNPs. Also, various laminated neat adhesive and nanocomposite (types I and II) in layup methods and SB joint with neat adhesive were prepared for the joints. Experimental results show that among all methods, layup II has a significant increase in joint strength. In particular, the enhancement of failure load in layup II is 31%, 25%, 73%, and 51% higher than SB, layup I, III, and IV, respectively. In fact, the location of each layer and bondline thickness has a great impact on joint strength.

摘要

在本文中，每种方法的效果都由纯粘合剂和纳米复合层的新粘合剂铺设方法组成，并在单搭接接头（SLJ）中提出了简单粘合（SB）接头。将石墨烯纳米粒子 (GNP) 添加到 Araldite 2011 粘合剂中，并选择钢 304 作为被粘物。两种类型的石墨烯（I 型和 II 型）用于纳米复合材料的构建，它们的主要区别在于 GNP 的特性。此外，还为接头制备了各种层压纯粘合剂和纳米复合材料（I型和II型）以及带有纯粘合剂的SB接头。实验结果表明，在所有方法中，layup II 的接头强度都有显着提高。特别是，叠层 II 中失效载荷的增加分别比 SB、叠层 I、III 和 IV 高 31%、25%、73% 和 51%。实际上，
