Abstract:
The Young modulus and the Poisson coefficient of two-dimensionally extended columnar graphene are theoretically studied in the uniaxial tension. The effect of length and diameter of nanotubes constituting the composite is considered. The numerical experiments are implemented using the minimum structural link and the periodical boundary conditions via the density functional theory method. The Young moduli of the composite are evaluated upon its extension along the normal to the graphene and along the graphene directions with increasing lengths of carbon nanotubes (CNTs) in the composite. The Poisson coefficient for this type of composites is found to be 0.025.
