The aim of this paper is to evaluate the fatigue behavior of the metallic fiber-reinforced adhesives. Single Lap Joints (SLJ) with various fiber distances were fabricated and tested under various fatigue loading levels to obtain the stress-fatigue life curves. The experimental results revealed that incorporation of the metallic fibers in adhesive layer improves the load sharing in the bonding line resulting in higher fatigue strengths for the case of reinforced adhesive joints. © 2020 The Authors.

1. Introduction

Various methods have been used in the past to improve the mechanical strength of adhesively bonded joints such as modifications of adhesive materials by incorporating additives (Kinloch et al., 2003; Zhai et al., 2006; Fereidoon et al., 2010; May et al., 2010; Ayatollahi et al., 2017a; Kanar et al., 2018; Razavi et al., 2018a,b; Akpinar et al., 2018) and modifications of the adhesive joint geometry (Boss et al., 2003; Fessel et al., 2009; Campilho et al., 2001; Rincon et al., 2013; Ayatollahi et al., 2017b; Razavi et al., 2018c,d, 2019).
