The effects of the adhesive thickness, the adherend surface roughness, and the fiber angles of the bonding surface of the adherends on the static and dynamic performance of the adhesive bonded tubular single lap joints were experimentally investigated. Also, the static stress distribution and torque capacity of the joints were analyzed by finite element method. The adherends of the joints composed of a steel shaft and a carbon fiber epoxy composite tube. The static torque capacity was proved to be much higher than the numerical values and the fatigue strength was proved to be about 30% of the static numerical values.
The fatigue and static strength of the joints were found to be inversely proportional to the adhesive thickness and the adherend fiber angles of the bonding surface were found to have no effect on the fatigue strength.
