A finite element model was established to analyze the failure behavior of unbalanced adhesive joint in carbon fiber drive shaft under torsion loading. Then the failure torque and failure mode of the unbalanced adhesive joint was predicted from the finite element model. It is found that the failure torque,failure mode in the torsion experiment were in close agreement with the result from finite element analysis. The effect of shear modulus ratio and wall thickness ratio between metal shaft head and carbon fiber tube on the failure behavior of unbalanced adhesive joint are discussed,which provides available reference in designing adhesive bonded joints in carbon fiber drive shaft.
