Since their discovery in early 1990âs, carbon nanotubes (CNTs) have been extensively studied. The studies on the fabrication and properties of CNTs, either as single nanostructures or as Nano-composites, have become one of the most attractive research topics in the material physics and Nano-technology. The remarkable electrical, mechanical, and thermal properties of (CNTs) enable them to be used for the development of Nano-electromechanical devices and new materials with the high mechanical strength, low mass densities and outstanding electrical and optical properties. Actually, CNTs are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. The advanced mechanical properties have lead to a great motivation for mechanical, aerospace and civil scientists and scholars to reveal and explore the potential applications of different CNTs and the Nano-structures.
