Fatigue failure analysis of CFRP single-lap adhesive-riveted hybrid joints

Abstract

The damage evolution and failure of single-lap riveted joints and adhesive-riveted hybrid joints in carbon fibre-reinforced plastic (CFRP) are analysed in this study. Results show that a slight increase in load leads to a considerable decrease in service life. Because a load increment increases the service temperature. When the riveted joint is not bonded with adhesive, the damage at the lap plate interface under the two types of loads is similar, and the damage on the hole wall is worse than that at the contact interface. The addition of adhesive improves the fatigue performance of the CFRP riveted joint and can reduce the sensitivity of the structure to external excitation loads.
