A displacement-based stiffness method is used to study the characteristics of dispersive wave propagation in laminated composite cylindrical tubes. It is assumed that the tube is composed of several bonded, uniaxial or angle-ply composite laminates. The objective is to model modes of propagation in composite tubular struts that are to be used for truss elements of space structures. Numerical results are presented showing the dependence of dispersion characteristics on the fiber orientations in the laminae.
