In the present work, a ballistic material-model development approach is combined with transient non-linear dynamics simulations of the projectilearmour interactions to explore the armour-hard-facing potential of multi-walled carbon nanotube MWCNT reinforced, polyvinyl- ester-epoxy PVEE-matrix composite mats. This approach is applied to improving the ballistic-protection performance of E-glass fibre-mat reinforced PVEE-matrix laminate armour. Two different architectures of the MWCNT-reinforcedPVEE-matrix composite mats were considered a a MWCNT-ply mat structure in which the MWCNT reinforcements are aligned parallel to the armour faces and b a MWCNT-forest mat structure in which the MWCNT reinforcements are aligned orthogonally to the armour faces. The projectilearmour interaction simulation results showed that, at low volume fractions of MWCNTs, both armour architectures yield no discernable increase in the armour ballistic-protection performance as measured by the armour. On the other hand, at high MWCNT volume fractions of MWCNTs, the first armour architecture remained ineffective whereas the second showed a minor improvement in the ballistic-protection performance relative to the corresponding monolithic armour. These results were rationalized using published experimental observations pertaining to the effect of MWCNTs on the in-plane and the through-the-thickness properties of fibre-matpolymer-matrix composite materials.
