Abstract:
Based on the software ABAQUS, the strength prediction model of carbon fiber reinforced polymer(CFRP)-aluminum bonded-bolted hybrid double-lap joint was built and simulation analysis was carried out. Comparing with the test result, the failure modes and the carrying capacity of the joint were studied under the tensile load condition. It is shown that the adhesive joint can be reinforced with the load-sharing of the bolt. The hybrid joint firstly suffers the fracture failure of the adhesive and reaches the final failure when the bearing failure appears near the hole. The carrying capacity of the joint predicted by the model has the error value of 9.7%, which illustrates good consistency with the test result. This method can offer some references for the analysis and design of the composite-metal bonded-bolted hybrid joints.
