Arresting Crack in Composite Bonded Joint Under Fatigue Using Fiber-Reinforcement-Based Feature
Development of new design features that stop cracks from growing above a critical size is one of the key steps to realization of boltless composite structures. The authors have proposed a fiber-reinforcement-based concept that introduces continuous fibers in the adhesive layer and suppresses the crack propagation using massive fiber bridging. Following the previous study evaluating the arrester performance under mode-I and mode-II static loading conditions, this current study conducts crack lap shear (CLS) fatigue tests to evaluate the performance under a realistic condition. In addition, the arresting mechanism is clarified using finite element analysis.
