dc.description.abstractComposite materials based on UV-curing acrylates and various alumina-based reinforcements represent material that is suitable for the use in dentistry, but also in other areas. Composites were made using four different types of reinforcement of chemically very similar compositions, but different size and morphologies. In order to monitor the mechanical properties of the composite material, samples were made in the form of discs of defined dimensions suitable for polymerization under UV light. The subject of this study is the examination of the mechanical properties of the Bis-GMA (Bisphenol A glycidyl methacrylate)/TEGDMA (trimethylene glycol dimethacrylate) photopolymer composite material as a matrix. The reinforcements were in the form of commercial nanoparticles and alumina whiskers and their influence on mechanical properties were compared with the influence of synthesized alumina particles doped with iron oxide synthesized sol-gel technique. In order to test the mechanical properties of composite materials, the Brazilian Tests and the testing of the microhardness of samples were employed.en
dc.description.abstractKompozitni materijali na bazi fotopolimerizujućih akrilata i različitih ojačanja na bazi aluminijum-oksida predstavljaju materijal koji je pogodan za upotrebu u stomatologiji, ali i u drugim oblastima. Kompoziti su napravljeni korišćenjem četiri različita tipa ojačanja hemijski veoma sličnih sastava, ali različite veličine i morfologije. Da bi se pratila mehanička svojstva kompozitnog materijala napravljeni su uzorci u formi diskova definisanih dimenzija pogodni za polimerizaciju pod dejstvom UV svetlosti. Predmet ovog istraživanja je ispitivanje mehaničkih svojstava fotopolimerizujućeg kompozitnog materijala na bazi Bis-GMA (Bisfenol A glicidilmetakrilata)/TEGDMA (trietilen glikol dimetakrilata) kao matrice. Ojačanja su bila u formi komercijalnih nanočestica i viskersa aluminijum-oksida i njihov uticaj na mehanička svojstva upoređen je sa uticajem sintetisanih čestica na bazi aluminijum-oksida dopiranih gvožđe oksidom sintetisanih sol gel tehnikom. Za ispitivanje mehaničkih svojstava kompozitnih materijala korišćen je Brazilski test i ispitivanje tvrdoće uzoraka.sr
