Abstract：
To take full advantage of the excellent properties of carbon nanotube (CNT), a 3D CNT-based nanostructure was designed theoretically by orderly connecting CNTs with different diameters. It was validated by the first principle that the present nanostructure had stability with a minimum energy of the system. Finally, the Young＇s moduli and strength of the 3D CNT-based nanostructures under tension and compression were predicted using the molecular dynamics (MD) method. The results show the moduli and strengths of the 3D CNT-based nanostructures can reach 185~260 GPa and 67~97 GPa. The 3D CNT-based nanostructures are more stable under compression for the existence of the supporting tube. ©, 2015, Beijing University of Technology. All right reserved.
