The dependences of their mechanical properties on the crystalline direction and the relative mass density are examined. Our MD simulations show that the tensile strength, tensile energy absorption, in-plane elastic modulus and compressive strength of ANHCs can be significantly reinforced by graphene-coating, whereas the compressive energy absorption capacity of GANHCs until densification is lower than that of ANHCs. A modified Gibson-Ashby model is developed to estimate the in-plane Young’s modulus and compressive strength of GANHCs, which shows a good agreement with the MD results.This work was supported by the National Natural Science Foundation of China (Grant Nos. 11772145 and 11372126).
