Composite pipes are always used together with joints and the bonding strength between them is a de鄄

termining factor for the pipes properties. The tensile strength of the composite pipes affected by memory alloy ring

have been analyzed with finite element analysis. And then tensile test were conducted for comparison. The experimental results indicate that the tensile strength of composite pipes could be enhanced by 10. 1% which meet the finite element analysis results. The present results provide a reference for the designing and optimization of composite pipes.
