title = "AVOIDING COMPLETE FAILURE OF COMPOSITE T-JOINTS BY EMBEDDING SACRIFICIAL CRACKS INSIDE THE BONDLINE",
abstract = "A novel CFRP bioinspired adhesive T-joint that mimics the structure of the bondline of a biological systems that has excellent adhesion, mytilus californianus, was designed. We embedded sacrificial tailored defects inside the adhesive bondline to allow progressive failure mode in the bioinspired T-joint by delocalizing the damage from the skin/adhesive interface. The presence of the sacrificial cracks inside the bondline improves the interlaminar fracture toughness of the stiffener/skin interface and hence improve the joint toughness. The improvement of the interface toughness delays the catastrophic failure of the joint and lead to initiation of damage inside the stiffener and the skin that further increase the toughness and provide progressive damage mode. The strength and toughness of the bioinspired T-joints are 2 and 17 times larger than the conventional T-joint, respectively. The growth of progressive damage inside the skin and the stiffener inhibited the catastrophic and complete failure of the joint.",
