Summary: | Super carbon nanotubes (STs) are a kind of hierarchical structure built by carbon nanotubes (called CNT arm tubes). Due to their complicated structure, the mechanical properties of STs are difficult to predict. In this work, an invariability phenomenon is uncovered in the mechanical properties of STs: both the in-plane stiffness and the shear stiffness of STs are independent of the ST chirality or CNT arm tube chirality. The bending rigidities of STs are also studied. From the in-plane stiffness and bending rigidity, the equivalent thickness of STs is calculated and found to be approximately a linear function of the CNT arm tube aspect ratio. |
