作为周期性重复碳纳米管Y结的结果，最近已经提出了超级蜂窝结构。本文采用有限单元法中的壳模型，对这类结构的力学性能进行了研究。研究表明，超级蜂窝结构具有很大的柔性和优异的传力能力;网络结构增加了纳米材料的延展性。此外，可以得出结论，等效拉伸模量和泊松比的超级结构是依赖于在宽度方向上的连接的数量。
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.
