Abstract

AA2024-T4 Al substrate with and without bonded E-glass/Epoxy patches were undergone for the experimental study of tensile strength and fatigue behavior. The Al substrates were machined to edge cracked specimens. The strength of the substrate was decreased due to the presence of crack when compared with un-cracked Al substrate. The patches were made in liquid epoxy resin instead of film adhesives and it was discovered that the both static strength and fatigue life were significantly increased for bonded composite patches. Different ply patches were applied on the cracked Al substrates and it was noted that the 9ply patch demonstrated its effectiveness in preventing static failure and increasing fatigue life of the cracked substrates
