In order to control the riveting interference and minimize the damage of GFRP composite caused by riveting, it is necessary to study the influence trend of riveting squeeze force on the interference of ${\Phi4}\mathrm{\;{mm}}2\mathrm{A}{10}$ rivet. The dynamic riveting process and the interference of the rivet have been simulated by ABAQUS on the effects of diameter of pre-drilled hole and riveting squeeze force of ${\Phi4}\mathrm{\;{mm}}2\mathrm{A}{10}$ aluminum alloy rivet on GFRP composite and aluminum alloy layers. On the basis of the simulation the experimental investigations are performed. The Interference test and metallographic analysis of the specimens are conducted. Results indicate that the interference of the same measurement location in the rivet increases with the increase of the riveting squeeze force and the interference with the same riveting squeeze force decreases through-the-thickness. ${\Phi4.2}\mathrm{\;{mm}}$ diameter of pre-drilled hole and ${18.3}\sim {18.7}\mathrm{{kN}}$ riveting squeeze force can achieve the optimum interference and the GFRP composite has no apparent injuries.
