The interfacial structure formed with silane coupling agents influences the inter-facial properties between the reinforcement and matrix in glass fiber reinforced composite. However, the interfacial structure at the molecular level has not yet been evaluated sufficiently. Therefore, a numerical analysis method is expected to estimate the interfacial structure on a molecular level. In this study, we proposed a formation model of interfacial structure, and tried to evaluate the model with fractal dimensions that can classify complex shapes. We proposed a model of interfacial structure for the finite element method, and investigated the relationship between the interfacial structure and the stress transmission mechanism. Moreover, we compared the results of numerical analysis with interfacial transmissibility in order to verify this analysis method. It was clear that the difference in interfacial structure influenced the mechanical properties at the interface. The above result suggests that this analysis method is useful for the investigation of the effects of interfacial structure on the interfacial properties.
