Micromechanical modeling of nanoreinforced composites with carbon nanofibers and interphase Conference Paper uri icon

abstract

  • A parametric study has been performed to investigate the effect of carbon nanofiber morphology (i.e., hollow versus solid cross section), nanofiber/resin interphase properties and dimensions, and nanofiber waviness on bulk nanocomposite mechanical properties. Mori-Tanaka and self-consistent models have been developed for composites containing multilayered coated heterogeneities. For a given weight/volume fraction of solid carbon, use of straight hollow nanofibers leads to a significant increase in the predicted mechanical properties. In addition, the development of a nanofiber-resin interphase can have a profound effect on bulk elastic moduli. Consistent with results from the literature, small degrees of nanofiber waviness can result in a significant decrease in effective composite properties.
