ABSTRACT
In this study, graphene is introduced to the cementitious matrix to improve not only the mechanical properties of the matrix but also the bonding properties. This study proposes a finite element model for graphene modified FRCM composite and validates the model by comparison against experimental results. Results showed that the increase of the mortar stiffness due to the introduction of graphene would lead to the increase of the elastic stiffness but the decrease of the strain of the composite. The stronger interfacial bonding brought by graphene would result in less strain developed at the cracking development stage. Graphene also led to more in-depth penetration of matrix into fibre bundles, which increases the ultimate strain of the composite. In addition, the constitutive models generated from parametric study were also used to assess two existing analytical models.
