Abstract

Tema ovog rada su polimerni kompoziti ojačani prirodnim česticama. S obzirom na ubrzan razvoj tehnologije i sve veće potrošnje sirovina prilikom proizvodnje, pronalazak obnovljive sirovine je nešto čemu treba težiti. Prirodna ojačavala su ekološki prihvatljiva alternativna sintetičkim ojačavalima zbog svoje recikličnosti, obnovljivosti i manje potrošnje energije prilikom izrade. Polimerni kompoziti ojačani prirodnim vlaknima, česticama ili drugim oblikom obnovljih sirovina imaju svijetlu budućnost među proizvodnim materijalima, a optimalan proizvod može se izraditi upotrebom i biorazgradive matrice. Cilj rada je istražiti polimerne kompozite ojačne česticama raznih biljaka i plodova, svojstva takvih kompozita te zaključiti hoće li se u budućnosti isplatiti razvijati ovakav tip kompozita kako bi se smanjilo opterećenje na okoliš.

Abstract (english)

The thesis of this paper are polymer composites reinforced with natural particles. Given the accelerated development of technology and the increasing consumption of raw materials during production, the invention of renewable raw materials is something to strive for. Natural reinforcements are an environmentally friendly alternative to synthetic reinforcements due to their recyclability, renewability and lower energy consumption during manufacturing. Polymer composites reinforced with natural fibers, particles or other forms of renewable raw materials have a bright future among the production materials, and optimal products can be made not only using natural reinforcement but adding biodegradable matrices as well. The aim of this paper is to look into polymer composites reinforced with particles of various plants and fruits, the properties of such composites and to conclude whether it’s cost effective to develop this type of composites in the future in order to reduce the impact on the environment.
