dc.description.abstractNovi materijali bazirani na drvetu imaju tu prednost da im se svojstva mogu podešavati kako bi odgovarali zahtevima kupaca. Svojstva koja je moguće podešavati odnose se kako na korišćenje tako i na obradljivost, a to su zatezna čvrstoća, elongacija pri prekidu, modul elastičnosti i otpornost na udar. Istraživanje na Šumarskom fakultetu i Hemijskoj industriji "HIPOL" odnosi se na novi tip drvno-polipropilenskih kompozita. Maseni sadržaj punioca u vidu drvnog brašna bukve variran je u opsegu od 40-70%. Pri dostizanju najveće zatezne čvrstoće sa sadržajem od 50% punioca ispitivan je i uticaj porekla drvnog punioca pri ovom sadržaju. Zbog toga je korišćeno drvno brašno od bukve, topole, acetilovane borovine i od MDF ploče. Takođe, istraživan je uticaj sastava drvnog punioca (bukva u kombinaciji sa MDF, topolom i acetilovanom borovinom) u poređenju sa čistom polipropilenskom matricom, kao i uticaj tipa kuplujućeg agensa. Rezultati dobijeni u ovom radu mogu da posluže kao inicijalni podaci za proizvodnju čvrstih i lako obradljivih kompozita.sr
dc.description.abstractNew materials based on wood have the advantage in the sense that their properties can be engineered so as to correspond to user demands. The properties which can be engineered are those relating both to their utilisation and machining, in particular - the tensile strength, elongation at break, modulus of elasticity and impact resistance. The research at the Faculty of Forestry and "Hipol" Chemical Industry related to the new type of wood-polypropylene composite. The content of wood filler was varied in the range between 40% and 70% mass contents of beech wood flour. After the highest tensile strength at 50% of filler content was determined, the effect of the wood filler origin was also examined at this content value. Therefore, wood flour of beech, poplar, acetylated pine and the waste MDF was used. The influence of the composition of the wood filler (beech combined with MDF, poplar and acetylated pine) in comparison with pure polypropylene matrix was also examined, as well as the effect of the type of coupling agent. Hopefully, the results obtained in this study might serve as the initial data for production of easily machined high-strength composites.en
