AB - In this paper, elastic modulus and critical strain energy release rate (GIc) of the interface region in glass/siloxane are characterized using the molecular dynamics method. In glass/epoxy composites, chemical bonding between polymeric coatings (siloxane) and fiber represents the interface region. Many investigations only considered the van der Waals forces for interface characterization. However, we apply covalent bonds along with van der Waals and electrostatic forces as influential forces to simulate the mechanical behavior of this region. The energy method is applied to characterize the interface properties, including GIc and elastic modulus. These properties are extracted from the variation of interface energy and bond breakage during the interface separation. To verify the results, we compare the elastic modulus of the glass/siloxane layer from the component elements with the results extracted from the constant strain method. Also, it is shown that the obtained results are in good agreement with the atomic force microscopy (AFM) predictions for elastic modulus at the interface of glass/epoxy composites and the available GIc in the literature.
