Abstract

Abstract: The properties of carbon fibers and matrix in carbon fiber reinforced polymers (CFRP) are different, and the resin matrix is sensitive to humidity, so the mechanical properties of riveted composite structures in service in a humid environment differ greatly from those in the laboratory environment. The hygroscopic aging test was designed and the experimental data were fitted using the Zhan’s model to obtain the variation of mechanical properties of CFRP under hygroscopic aging condition, the failure mechanism of the aged material was also studied. Based on this prediction model, a finite element simulation model of composite riveted structure with moisture absorption and aging under different assembly conditions was established, the accuracy of the model was verified by experiments. The effects of moisture absorption aging and assembly method on the bearing performance and failure mechanism of composite and the whole joint structure were investigated by a combination of finite element simulation and experiments.

Key words: CFRP, hygroscopic aging, blind rivets, interference/clearance fit, finite element simulation
