Abstract: In order to study the failure mechanism of the single-lap two-bolt bonded-bolted hybrid connection of carbon fiber reinforced polymer (CFRP) laminates, the continuous progressive degradation method based on fracture energy fracture criterion was used to simulate the stiffness degradation of CFRP laminates, and the B-K criterion based on energy was used to simulate the damage evolution of the adhesive layer. A three-dimensional finite element model of progressive damage of the bonded-bolted hybrid connection structure was established. The maximum failure load predicted by the finite element model is in good agreement with the experimental results. Lap length L_a is an important geometric parameter affecting the stiffness and strength of the bonded-bolted hybrid joint. The position of bolt will not significantly affect the stiffness of joint. The larger the bonding area, the greater the strength. Under the action of tensile load, the bolt of the bonded-bolted hybrid joint is inclined to the left due to the influence of the secondary bending effect. The adhesive layer damage in the overlap area starts from the outside of the adhesive layer in the overlap area and expands from the outside to the inside to the vicinity of the bolt hole. When the damage of the adhesive layer extends to the vicinity of the bolt hole, the load of the bolt increases, and the adhesive layer and the bolt bear the load together. At this time, the CFRP laminates begin to damage, and the upper composite plate at the left hole and the lower composite plate at the right hole produce delamination damage and fracture.
