Abstract

In order to study the effects of different parameters on the mechanical properties of composite mixed (bolted/bonded) joint structure, this paper built a CFRP/steel single shear double-nail mixed joint structure model based on the known material parameters, Hashin criterion and quade adhesive layer failure criterion, and established a finite element simulation model in Abaqus software. Parameters such as lay-up Angle, lay-up thickness, hole size, bolt end distance and so on were changed respectively. The simulation results show that when the lay-up Angle is [0/45/90/-45]_2s, the lay-up thickness is 0.26mm, the opening size is 5mm, and the end distance is 7.5mm, the overall connection strength of the structure is the highest.
