Abstract

Recent developments in nanotechnology make it possible to fabricate nanofibers and identify their mechanical fibers. In particular, nanofibers are used as reinforcement in composites. The present work concerns unidirectional nanofibrous composites with cylindrically anisotropic phases and aims to analytically estimate their effective thermoelastic moduli. This objective is achieved by extending the classical generalized self-consistent model to the setting of thermoelasticity, to the case of cylindrically anisotropic phases, and to the incorporation of interface stress effect. Analytical closed-form estimations are derived for all the effective thermoelastic moduli, showing that these moduli depend on the fiber cross-section size. Numerical examples are provided to illustrate this size-dependent effect.
