The diameter typically varies from 0 1996-01-01 · This chapter discusses some aspects of the mechanical and thermal properties of carbon nanotubes. The tensile and bending stiffness constants of ideal multi-walled and single-walled carbon nanotubes are derived in terms of the known elastic properties of graphite. Se hela listan på ctimaterials.com Properties of Carbon Nanotubes Physical – Carbon nanotubes are inherently stronger than other modern materials, giving it extreme stiffness and strength. These have been successfully developed to a record-breaking length-diameter ratio of over 132,000,000:1, stronger than most other most durable materials. Mechanical and Physical Properties • Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively.
