Original abstract
Ab initio calculations of elastic moduli and theoretical tensile strength of composite lamina having continuous nano-fibre reinforcements are performed using pseudo-potential approach within density functional theory. Results for molybdenum or tungsten nano-fibres in vanadium or niobium matrixes, presented as case studies, reveal that the theoretical strength approaches the value corresponding to the strength of the reinforcement already at about 60-80% atomic concentration of reinforcing fibres in the composite.
Czech abstract
Ab initio výpočty elastických modulů a teoretické pevnosti kompositů se spojitou nanovláknovou výztuží jsou provedeny pseudo-potenciálovým přístupem v rámci density functional theory. Výsledky pro molybdenum nebo wolframová vlákna ve vanadiové nebo niobové matrici, presentované jako konkrétní studie, ukazují, že teor. pevnost dosahuje hodnot srovnateklných s pevností výztuže již při její atomové koncentraci v kompozitu cca 60%.
