Abstract

Vibroacoustic behavior of graphene reinforced composite plate (GRCP) is studied to investigate the sound transmission loss (STL), Due to the importance of the behavior of the structure against sound waves. Many materials have been used to increase the stiffness and improve the vibroacoustic behavior of sandwich structures. which in recent years, Graphene has prompted many researchers to use it in sandwich structures. Governing equations are derived based on three-dimensional elasticity and state vector method is used to solve equations of motion. To evaluate the validity of the results from previous studies, two studies that have examined the sound transmission loss of plate have been used. To find the effective parameters on the amount of plate STL, changes in graphene weight fraction, plate thickness, incidence angle, thickness of graphene nanoplatelets (GPLs) and width of GPLs are investigated. Finally, numerical results show that adding a small amount of GPLs to the composite matrix increases its stiffness and thus improves the behavior of the structure against the pressure of sound waves. Also, Increasing the plate thickness has a good effect on the STL, and increasing width of GPLs with constant length has no effect on the vibroacoustic behavior of the structure.
