A review on functionally graded porous structures reinforced by graphene platelets

Nowadays, there is a high demand for great structural implementation and multifunctionality with excellent mechanical properties. The porous structures reinforced by graphene platelet (GPLs) having valuable properties, such as heat resistance, lightweight, and excellent energy absorption, have been considerably used in different engineering implementations. However, stiffness of porous structures reduces significantly, due to the internal cavities, by adding GPLs into porous medium, effective mechanical properties of porous structure considerably enhance. To boost the efficiency and capability of structures, functionally graded (FG) porous structures reinforced by GPLs have been suggested in the literature. Therefore, some researchers tried to figure out the fantastic characteristics of these structures and research activities in this emerging area have been rapidly increasing. The present paper (a) briefly reviews the mechanical properties of functionally graded porous composites reinforced by GPLs and discusses the existing micromechanics model for the prediction of effective mechanical properties; (b) presents a comprehensive review on the mechanical analyses of these structures; (c) discusses the challenges and possible future works.
