abstract

  • A micromechanics parametric study was performed to investigate the effect of carbon nanofiber morphology (i.e. hollow vs. solid cross-section), nanofiber waviness, and both nanofiberresin interphase properties and dimensions on bulk nanocomposite elastic moduli. MoriTanaka and self-consistent models were developed for composites containing heterogeneities with multilayered coatings. For a given nanofiber axial forcedisplacement relationship, the elastic modulus for hollow nanofibers can significantly exceed that for solid nanofibers resulting in notable differences in bulk nanocomposite properties. In addition, the development of a nanofiberresin interphase had a notable effect on the bulk elastic moduli. Consistent with results from the literature, small degrees of nanofiber waviness resulted in a significant decrease in effective composite properties.
