Summary:This study is aimed to predict the effect of layering of graphene sheets (GSs) embedment in conventional carbon matrix of 4-dimensional carbon/carbon (4D-C/C) composite on the elastic modulus of 4D-C/C composite. Molecular dynamics methodology is employed to execute the nano-scale modeling and analysis of the single GS/layered GSs. Predicted elastic modulus of GS/GSs is utilized to estimate the elastic modulus of GS/GSs reinforced carbon matrix by employing semi-empirical Halpin–Tsai approach. At macro-scale, finite element methodology is utilized and elastic modulus of GS/GSs reinforced 4D-C/C composite is predicted. The elastic moduli of 4D-C/C composite are established to be improved in compared to the without GS/GSs reinforced 4D-C/C composite, due to better load carrying capacity of GSs embedded carbon matrix. Therefore, GS-embedded 4D-C/C composites can successfully replace currently used C/C composites for high strength applications.
