N2 - Fiber/matrix interphase in composite materials plays an important role on its structural performance. However, structure and properties of this region are not completely known, due to lack of understanding of the processes occurring at atomic/molecular level during formation of interphase and comprehensive experimental methods for characterization of interphase. In addition, most of the currently used experimental techniques are available for micron size fibers and are not sufficient to characterize the nanofiber/matrix interphase. Recently, molecular dynamics simulations have shown promising results in obtaining the mechanical properties of fiber reinforced polymer composites. The objective of this study is to determine the mechanical properties of silane treated glass nanofibers and epoxy resin interphase using molecular dynamics simulations. To simulate the interphase (blend of sizing/coupling agent and matrix), atomistic models of blend of silane coupling agent (3-aminopropyl) triethoxysilane (APTES) and cross linked epoxy 862 resin system are developed. Mechanical properties of the interphase are predicted for different weight fractions of silane using molecular dynamics simulation.
