dc.description.abstractMaterijali u vidu tkanina koje se proizvode od vlakana velike žilavosti koriste se u antibalističkoj zaštiti zbog svoje male gustine, velike otpornosti na udar i velikog kapaciteta apsorbovanja energije. Poslednjih godina para-aramidne tkanine (lamine) imaju veliku primenu u formiranju kompozitnih struktura koje se koriste za proizvodnju zaštitne opreme za telo. Njihova izvanredna mehanička svojstva potiču od dugačkih, pravih poli (parafenilen tereftalamid) vlakana. Povećanje modula skladištenja ili čvrstoće polimera u kompozitu postiže se dodavanjem ojačanja. Različiti parametri ojačanja se uzimaju u obzir pri njihovom odabiru za uspešnu realizaciju u kompozitu. Ugljenične nanocevi (engl. Carbon nanotubes – CNT) predstavljaju odličan izbor kod odabira ojačanja za polimerne kompozite zbog njihovog velikog odnosa dužina/prečnik (koji je oko 132000000), velike čvrstoće, malih dimenzija i mase, i velike provodljivosti.sr
dc.description.abstractMaterials in the form of fabrics made of high tenacity fibers are used in antiballistic protection due to their low density, high resistance and high energy absorption capability. In recent times, paraaramid fabrics have had a wide range of applications in the construction of composite structures for the production of the antiballistic body armour protection. Their excellent mechanical properties originate from the long, straight fibers of poly (paraphenylene terephthalamide). The increase of the storage modulus or the stiffness of polymers can be achieved by adding reinforcement. Carbon nanotubes (CNT) present a perfect choice as reinforcement in polymer composites because of their high aspect ratio (length/diameter ratio, around 132000000), great stiffness, small size, small mass and high conductivity.sr
