In the current work, the effect of weight percentage and orientation of multi-walled carbon nanotubes (MWCNTs) on the mechanical properties of unidirectional (UD) carbon fiber (CF)/MWCNT/epoxy composites was studied by using multiscale material modelling and finite element analysis (FEA). Nanoscale representative elementary volume (RVE) consisting of MWCNTs and microscale RVE consisting of carbon fibers were generated using DIGIMAT FE Software. The equivalent elastic properties obtained from MWCNT/epoxy composites were used to estimate effective elastic constants of UD carbon fiber/MWCNT/epoxy composites. The weight percentage of MWCNTs was varied 0%–5%, while MWCNTs were orientated at 0°, 30°, 45°, 60° and 90°. It was found that the E1, E2, G12, υ12 and υ23 increased by 1.79%, 6.14%, 2.83%, 8.8% and 5% at 5 wt% addition of MWCNTs respectively. It was also found that except transverse young's modulus (E2) all other elastic constants decreased by increasing the orientations and at 90° the transverse Young's modulus (E2) increased by 16.57% compared to 0° orientation at 1 wt% addition of MWCNTs. The multiscale FE analysis results were compared by multiscale micromechanics model.
