A novel composite coupling is proposed: flexible hyperbolic compositecoupling. In addition to enjoying the advantages of composite materials, theproposed coupling provides some of the needed damping and can be readilyintegrated with composite drive shaft into a single unit. A mathematical model ofthe coupling is developed based on the Timoshenko beam theory using the energyapproach and the extended Lagrange’s equations. The corresponding discreteequation of vibration is obtained using the finite element method and solved for thenatural frequencies using MATLAB. The dynamic characteristics of the coupling(axial, torsional and bending natural frequencies) are studied in order to assess themerits and potential of the proposed coupling
