In this paper, the results of analytical investigation into the effects of cocuring fiber composite tubes with commercially available damping materials are presented. A comprehensive theory has been developed for studying the vibration of a composite tube with multiple viscoelastic damping layers. The effects of transverse shear deformation, transverse normal stress and strain, rotary inertia, and higher-order stiffness terms are included in the modeling along with shear correction factors. Resonance frequency and loss factor results as a function of various geometric and physical parameters are presented for composite tubes with single and double damping layers. It is demonstrated through a parametric study that in all these systems, careful selection of damping and pre-preg material is needed to optimize the damping benefits desirable and the stiffness reductions that can be tolerated.
