Fatigue behavior of single lap adhesive composite joints

Abstract

Adhesive bonding has a high potential for aerospace, automotive, and other structural applications. Adhesively bonded composite patches can be used to repair aerospace parts with minimum deterioration of aerodynamic contours. Although adhesive joints have been extensively studied during the past decades, the mechanisms of fatigue failure and life of joints are not yet sufficiently understood. The objective of this paper was to study mechanical behavior and mechanisms of damage and failure in single-lap composite joints under fatigue.
