The internal friction and in-plane natural frequency of a trilayer complex formed by a monolayer graphene sandwiched in the bilayer of boron nitride nanosheets (BN/G/BN) and graphenes (G/G/G) are studied by using molecular dynamics. The investigation shows that the internal friction coefficients for BN/G/BN (∼0.025) are significantly higher than that of G/G/G (∼0.015). The coefficients for both G/G/G and BN/G/BN increased with external pressure. The speed of increase is divided into quick increase, slow increase and saturation stage. The internal friction coefficients for G/G/G and BN/...
