Sažetak

Pri projektovanju aviona važno je koristiti lagane, ali mehanički čvrste materijale. U tu svrhu razvijene su mnoge nove kompozitne strukture, uglavnom na bazi jakih vlakana i vezivne smole. U ovom istraživanju razmatra se mogućnost pojačavanja kompozita na bazi karbonskih vlakana i epoksidne smole, dodavanjem male količine poli (vinil butirala), PVB i nanostruktura volfram disulfida. U eksperimentima su korišćene dve vrste nanočestica, obe poznate po dobroj mehaničkoj otpornosti: nanočestice nalik fulerenu i višeslojne nanocevčice, IF-WS2 i INT-WS2. Uzorci kompozita su pripremljeni tako da se sastoje od višeslojnih karbonskih vlakana impregniranih sa epoksidnom smolom i PVB rastvorom koji sadrži definisane koncentracije dispergovanih nanostruktura WS2. Nanočestice su posmatrane skenirajućim elektronskim mikroskopom, SEM. Mehaničke osobine višeslojnih kompozitnih uzoraka testirane su sa dve konfiguracije pravaca vlakana. Analizirani su uporedni rezultati i izvedeni zaključci koji podstiču buduću primenu ovih nanostruktura u cilju poboljšanja performansi kompozita za vojne avione.
