As a result of repeating carbon nanotube Y junctions periodically, super honeycomb structures have recently been proposed. In this paper, the mechanical properties of these structures are investigated by using the shell model of the finite element method. The study shows that the super honeycomb structures have great flexibility and outstanding capability in force transferring; the network configuration increases the ductility of the nanomaterials. Furthermore, it can be concluded that the equivalent tensile modulus and Poisson's ratio of super structures are dependent on the number of junctions in the width direction.
