Abstract

U posljednjih nekoliko godina primjećen je porast interesa za komercijalnom upotrebom kompozita na osnovi prirodnih vlakana, odnosno biokompozita. Interes za ovim materijalima javlja se uslijed zabrinutosti ljudi zbog potencijalne štetnosti i problema zbrinjavanja otpada koji nastaje upotrebom materijala na osnovi neobnovljivih izvora energije. Prirodna vlakna predstavljaju održive materijale, lako dostupne u prirodi, s nizom prednosti poput niske cijene, male težine, obnovljivosti, biorazgradivosti te visokih specifičnih svojstava. Istraživanje je usmjereno na ispitivanje mehaničkih i morfoloških svojstava kompozita termoplastičnog polimera i vlakana brnistre. Kao termoplastični polimeri za pripravu kompozita korišteni su polikarbonat (PC), akrilonitril butadien stiren (ABS) i polipropilen (PP) te vlakna brnistre
u udjelima od 0, 5, 10, 15 i 20 mas. %.

Abstract (english)

In the last few years, there has been a growing interest in the commercial use of composites based on natural fibers, i.e. biocomposites. Interest in these materials stems from the growing concern of people about potential harm and the problem of waste disposal arising from the use of materials based on non-renewable sources of energy. Natural fibers represent sustainable materials, easily available in nature, with several advantages such as low cost, light weight, renewability, biodegradability and high specific properties.
The mechanical and morphological properties of the composite of thermoplastic polymer and Spartium junceum L. fibers were investigated. Polycarbonate (PC), acrylonitrile butadiene styrene (ABS) and polypropylene (PP) were used as thermoplastic polymers for composite preparation as well as Spartium junceum L in the content of 0, 5, 10, 15 and 20 wt. %.
