▎ 摘　　要

The ballistic performance of graphene/silicon carbide laminates under nano-projectile impact is studied using molecular dynamics method, where graphene acts as a barrier coating for its unique intra-layer honeycomb-like structure and interlayer coupling effects. We reveal that under nano-indentation two-layer graphene with AB stacking on 4H-silicon carbide(0001) exhibits the highest hardness, 140.06 GPa, comparable to diamond. During impact, the specific total penetration energy of laminates increases with the number of graphene layers n, though the partial of graphene decreases as n
