Taking the composite-to-titanium hybrid structure as the research object, the load distribution characteristics and influence of different assembly forms on bolt load of co-cured, bonded and separated under the joint of two kinds of fasteners, such as the protruding and the countersunk, were analyzed. The stress distribution of the bolt hole in the joint area was measured by strain electric measurement. The numerical simulation model was established by ABAQUS software to analyze the bolt load distribu-tion of joints in composite laminate with metal. The results showed that the load distribution of the co-cured composite laminate with countersunk bolt joint is stepped from the loading end to the opposite end of the branch, while the load distribution of the other joints is high on both sides and low in the middle. The only difference is the proportions of bolt load in each row. The gaps of the separated composite laminate are the largest, the bonded are the second, and the co-cured is the smallest.
