Abstract

The magnitude of E and σ_b of multiwall nanotubes (MWNT) are directly measured by pulling ropes of very long well-separated parallel nanotubes with a stress-strain puller and the values of E = 0.45±0.23 TPa. This puller can apply an axial force to the rope and simultaneously measure the corresponding rope elongation and the change in rope resistance. The average Young's modulus and tensile strength obtained were 0.45±0.23 TPa and 1.72±0.64 GPa respectively, which are lower than those calculated and measured previously. The factors that affect the mechanical strength of nanotubes are discussed.
