Abstract
In this study we revised the axisymmetric vibration of an infinite thermo piezoelectric composite circular hollow cylinder made of inner and outer thermo piezoelectric layer bonded together by a Linear Elastic Material with Voids (LEMV) and Single Walled carbon Nano Tube (SWCNT) is studied. The frequency equations are obtained for the traction free outer surface with continuity conditions at the interfaces. The equations of motion, heat and electric conduction also exactly solved. Numerical results are carried out for the inner and outer hollow piezoelectric layers bonded by LEMV and SWCNT layers. The dispersion curves are compared with core/LEMV/core, core cylinders
