Anisotropic and tunable mechanical properties of graphene based asymmetric carbon honeycomb
Year: 2024
Type: article
Abstract: Graphene based three-dimensional (3D) carbon honeycomb has attracted enormous attentions due to its excellent physical properties and wide application promises. Based on atomistic simulations, we reveal that asymmetric carbon honeycombs (ACHs) under in-plane tension display anisotropic mechanical behaviors and possess novel yet tunable mechanical properties dependent of the honeycomb cell size. These unique cell-size dependent features cannot be predicted by the widely used Gibson’s continuum honeycombs model, and a new continuum theoretical model is developed to predict the results accurately. Under compression, ACHs can provide anisotropic and broad range options specific energy absorption capacity of carbon honeycomb. The present study reveals key structure-property relationships of ACHs under in-plane and out-of-plane tension/compression. Our results provide a useful guideline for the rational design of graphene based honeycomb structures with targeted properties for practical engineering application.
