Abstract
The experimental investigation were conducted in order to study the dynamic strength of the mechanically fastened composite joints, involving interference-fit joints with blind bolt and sliding-fit joints with high lock bolt. The joint type of the specimens researched was single-bolt, double-lap, which was a standard test configuration in ASTM for composite joints. Experimental results showed that the fatigue performance of the blind bolted joint was better than that of the high-locking bolted joint. The fatigue life of the blind bolted joints was 10-100 times higher than that of the high-locking bolted joint under the same cyclic stress, and the limit fatigue strength of the blind bolted joints was over 50MPa higher than hat of the high-locking bolted joints.
