Abstract (EN): Structural adhesive joints provide several benefits over conventional joining methods, such as more uniform stress distributions, higher resistance to fatigue and the possibility of joining different materials, which can lead to structures with reduced weight and cost. In addition, high performance structural adhesives are a key factor behind the growing industrial use of composite materials. As the transportation industry now faces a considerable challenge to reduce fuel consumption and vehicle weight in order to reduce pollutant emissions, bonded composite structures have become a desirable and economically viable solution for this problem. The behavior of composites is anisotropic in respect of stiffness and strength as a function of fiber direction. In the fiber direction, composites show the strongest behavior however, in the transverse direction, mechanical properties are much lower. The lower peel strength of composites therefore can cause bonded composite joints to fail in transverse tension (by a delamination of adherend mechanism) before the adhesive itself fails. Due this limitation of the composites, different methods have been proposed to reach the adhesive failure instead of delamination leading to increases in the composite joint strength. © 2021 Elsevier Ltd.
