Abstract (EN): Adhesive bonding is of major importance in many technological sectors, as it represents the most effective and practical technique to join composite components. However, some aspects of polymer composite materials, most importantly their low transverse strength, make these materials highly susceptible to delamination if the peel stresses generated in the adhesive layer are not correctly managed. Thus, several research works have proposed novel methodologies to reduce the delamination failure of bonded composites, either by reinforcing the composite itself to improve its resistance to delamination or, alternatively, by designing the joint in a manner which reduces the peak peel stresses generated in the adhesive layer and transferred for the substrates. This article provides a literature review and general considerations regarding the bonding process of composites, followed by a detailed description of a set of experimental works, carried out on the performance of composite bonded joints under impact, the use of mixed adhesive joint with composite substrates and techniques to improve delamination resistance of composite bonded joints via the use of fiber metal laminates and the other surface toughening techniques. © 2022 Elsevier Inc.
