The Young's modulus of a finite-sized zigzag carbon nanotube-based ribbon-like columnar graphene is theoretically studied. The dependence of elastic characteristics on the structural parameters of columnar graphene such as the length and diameter of carbon nanotubes constituting the composite is studied. In this case, within the limits of a particular composite, the structure parameters of carbon nanotubes remain constant. It was established that the Young's modulus increases with the increase in the carbon nanotube length and decreases with the increase in its diameter.
