Abstract

Smanjenje naftnih resursa i svijest o globalnim problemima doveli su do izvanrednih dostignuća na području znanosti o materijalima. Razvoj kompozita od obnovljivih izvora u porastu je diljem svijeta. Zahvaljujući velikom broju dobrih svojstava i karakteristika, kompoziti od obnovljivog porijekla pojavljuju se kao „zelena“ alternativa kompozitima ojačanim staklenim vlaknima. Postoji nekoliko vrsta ekološki prihvatljivih kompozita, a najviše se teži proizvodnji onih koji sadrže prirodna vlakna kao ojačanje i biopolimere kao matricu. S obzirom da visoka cijena polimerne biorazgradive matrice predstavlja glavno ograničenje kada je u pitanju njena široka uporaba, prirodna vlakna (u kombinaciji s plastomernom ili duromernom matricom) danas se nameću kao prihvatljiviji izbor pri izradi kompozita od obnovljivog porijekla. Ovaj rad daje pregled svojstava prirodnih vlakana i biopolimernih matrica, ali i samih kompozita od obnovljivog porijekla, te ukazuje na prednosti i nedostatke primjene istih.

Abstract (english)

The reduction of petroleum resources and awareness of global issues have led to extraordinary achievements in the field of materials science. The development of composites from renewable resources is increasing worldwide. Thanks to a large number of good properties and characteristics, composites from renewable resources appear as a „green“ alternative to glass fiber reinforced composites. There are several types of environmentally friendly composites, and the most significant are those containing natural fibers as reinforcement and biopolymers as matrix. High cost of biodegradable polymer matrix represents a major limitation when it comes to its wide usage, and because of that natural fibers (in combination with thermoplastics and thermosets) are imposed as an acceptable choice when developing composites from renewable resources. This paper summarizes the properties of natural fibers, biopolymer matrices, and composites from renewable resources, pointing out the advantages and disadvantages in their application.
