State-of-Art Review on Fatigue and Tension Behavior of Scarf Adhesive Joints

Scarf adhesive joints (SAJs) are increasingly used in composite structures due to their enhanced load transfer capabilities and structural efficiency. This literature review provides a comprehensive overview of SAJs, covering their fundamental geometry and function, and explores key mechanical properties under different loading conditions. The fatigue behavior of SAJs is discussed in terms of endurance limits and failure mechanisms. Tensile properties are reviewed with a focus on the influence of scarf angle and adhesive thickness. This review serves as a foundation for future research and optimization of SAJs in structural applications.
