Carbon nanotubes (CNTs) are one of the strongest known materials. When assembled into fibres, however, their strength becomes impaired by defects, impurities, random orientations and discontinuous lengths. Fabricating CNT fibres with strength reaching that of a single CNT has been an enduring challenge. Here, we demonstrate the fabrication of CNT bundles (CNTBs) that are centimetres long with tensile strength over 80 GPa using ultralong defect-free CNTs. The tensile strength of CNTBs is…

Chain Model for Carbon Nanotube Bundle under Plane Strain Conditions

An atomistic chain model is proposed to analyze the mechanical response of CNT bundles under plane strain conditions and is able to describe large curvature of the CNT wall and the fracture of the walls at very high pressures, where both of these problems are difficult to address in frame of continuum mechanics models.

Measurements of near-ultimate strength for multiwalled carbon nanotubes and irradiation-induced crosslinking improvements.

Multiwalled carbon nanotubes with a mean fracture strength >100 GPa are reported, which exceeds earlier observations by a factor of approximately three and are in excellent agreement with quantum-mechanical estimates for nanot tubes containing only an occasional vacancy defect, and are approximately 80% of the values expected for defect-free tubes.
