Newly Designed Adhesive Joint for Torque Loaded Tube
Adhesive joint is commonly applied to CFRP/GFRP composite tube, however, its failure rate is still high and this will limit the use of composite tube for industrial purpose. The literature study showed that the stress distribution at the joint, when loaded, is not evenly distributed and creates stress concentration at the edges. Attempts have been made by researchers to improve the joint design so that the stress would be more evenly distributed and minimize stress concentration, however, the improvement has been very limited. In this work, a comprehensive parameter study has been performed to observe the properties of adhesive joint of torque loaded tube. Based on the observation, a new type of adhesive joint is proposed which successfully reduces the stress concentration along the joint during torque loading. The analysis was performed using finite element method.
