The mechanical properties of the bonded joints, riveted joints and hybrid joints between carbon/glass fiber reinforced polymer (FRP) and steel plate were systematically studied by simulation and experiment, in which cohesive zone damage model, metal failure criterion and Hashin failure criterion were employed to simulate the cohesive failure of adhesive layer, rivet rupture and FRP damage, respectively. On this basis, the finite element model of hybrid joints was established by combining the three failure criteria, and the mechanical properties of the hybrid joints during tensile tests were predicted. The results show that the finite element model can accurately predict the maximum load, failure displacement, failure modes and complex failure process of the hybrid joints tests. It is noticeable that the glass fiber as braided yarn is torn in the hybrid braided FRP for the joints with adhesive layer. Besides, the effect of the adhesive thickness on the mechanical properties of the hybrid joints was also studied. With the increase of the adhesive thickness, the maximum load of the joint increases first and then decreases, and the area of the damage zone around the rivet hole of FRP plate increases gradually.
