Original abstract
Ab initio calculations of elastic moduli and theoretical uniaxial strength of composite lamina having continuous nano-fibre reinforcements are performed using pseudo-potential plane-wave code. Obtained results are used to verify validity of macro-scale empirical relations for composites (rules of mixtures) on the nano-scale. All quantities are computed from the dependence of crystal energy on a suitable deformation parameter. Results for molybdenum nano-fibres in vanadium matrix, presented as a particular example of the ab-initio analysis, reveal that elastic moduli of ideal composites increase with molybdenum concentration, following the simplest form of the linear mixture rule. On the other hand, the theoretical strength reaches the value corresponding to strength of pure molybdenum already at about 60% atomic concentration of Mo wires in the composite.
