This study presents a micromechanics model based on the variational asymptotic method for unit cell homogenization (VAMUCH) to predict the effective elastic properties of a continuous fuzzy fiber-reinforced composite material. The constructional feature of the fuzzy fiber-reinforced composite (FFRC) proposed in [S.I. Kundalwal, M.C. Ray, "Effective properties of a novel continuous fuzzy-fiber reinforced composite using the method of cells and the finite element method", European Journal of Mechanics A/Solids 36 (2012) 191-203] is that uniformly aligned carbon nanotubes (CNTs) are radially grown on the surface of the horizontal carbon fibers. The effective elastic properties of the fuzzy fiber-reinforced composite estimated by the variational asymptotic method have been compared with those predicted by the finite element based micromechanics approach (FEA) and the method of cells (MOC) approach reported in the previous reference. It has been also observed that the transverse effective properties of such a composite material are significantly improved due to the radial growing of CNTs on the surface of the carbon fiber. It is shown that two 2D unit cells can be successfully used within the VAMUCH for the intuitive prediction of the full effective 3D anisotropic properties of such FFRC. This lead to a reduced computational expenditure in comparison to the three 3D unit cells used in the FEA reported in the above reference. |
