| description | This investigation focuses on the design of functionalization configuration at the atomic level to determine the influence of atomic structure on the mechanical
properties of functionalized carbon nanotubes (F-CNTs) and their composites. Tension and compressive buckling behaviors of different configurations of CNTs functionalized
by H atoms are studied by a molecular dynamics (MD) method. It is shown that H-atom functionalization reduces Young’s modulus of CNTs, but Young’s modulus
is not sensitive to the functionalization configuration. The configuration does, however, affect the tensile strength and critical buckling stress of CNTs. Further, the stress-strain relations
of composites reinforced by nonfunctionalized and various functionalized CNTs are analyzed. |
