Abstract

Sve veća zabrinutost o iscrpljivanju resursa, kao i pojava sve većeg zagađenja usmjerila je mnoge znanstvenike i istraživače u posljednjih nekoliko godina na proizvodnju biokompozita. Sve veća komercijalna dostupnost polilaktidna (PLA) kao i njegova dobra svojstva, uključujući biorazgradljivost učinila su ga jednim od obećavajućih materijala. PLA biokompoziti koji sadrže anorganska punila ili ojačavala na osnovi prirodnih vlakana zauzimaju veliku pozornost zbog svoje biokompatibilnosti. Neke od prednosti korištenja prirodnih vlakana u biokompozitima su niska cijena, specifična svojstva i neabrazivna prerada. Zamjena određenog postotka biopolimera s vlaknima smanjuje cijenu materijala, a takvi bi materijali bili i potpuno biorazgradljivi. Shodno tome, istraživači su ispitivali učinkovitost PLA kompozita ojačanog prirodnim vlaknima kao alternativnog materijala za zamjenu neobnovljivih materijala na bazi nafte.

Abstract (english)

The growing concern about the depletion of resources, as well as the appearance of increasing pollution, has directed many scientists and researchers in the last few years to the production of biocomposites. The increasing commercial availability of polylactide (PLA) as well as its good properties, including biodegradability, have made it one of the most promising materials. PLA biocomposites containing inorganic fillers or reinforcements based on natural fibers are attracting a lot of attention due to their biocompatibility. Some of the advantages of using natural fibers in biocomposites are low price, specific properties, and non-abrasive processing. Replacing a certain percentage of biopolymers with fibers reduces the cost of the material, and such materials would also be completely biodegradable. Accordingly, researchers investigated the effectiveness of natural fiber reinforced PLA composites as an alternative material to replace petroleum-based non-renewable materials.
