Abstract
In this paper, the impact of wood fiber surface modification on mechanical properties of poly-(methyl methacrylate)(PMMA)-wood composite was examined. FTIR analysis has shown that the wood fiber surface modification was accomplished and that the matrix-fiber bond was established. The SEM image of the breakage surface has affirmed the improved adhesion between the fibers and the polymer in the specimen with modified wood fibers. The bond improvement between the wood fibers and the matrix results in increased hardness and a better distribution of strain within the composite. High speed impact testing results have shown that the specimen with the bonding agent can increase the absorbed energy six times when compared to the pure PMMA specimen.
U ovom radu izvršeno je ispitivanje uticaja modifikacije površine drvenih vlakana na mehanička svojstva kompozita poli-(metil metakrilat)(PMMA)- drvo. FTIR analiza je pokazala da je postignuta modifikacija površine drvenih vlakana, kao i da je ostvarena veza matrica-vlakno. SEM snimak površine loma uzorka takođe potvrđuje bolju adheziju vlakana i polimera u uzorku sa modifikovanim vlaknima drveta. Poboljšanje veze između drvenih vlakana i matrice omogućava veću čvrstoću i bolji prenos opterećenja unutar kompozita. Rezultati ispitivanja udarom kontrolisane energije pokazali su da uzorak sa vezujućim agensom može da poveća apsorbovanu energiju i do šest puta u odnosu na čist PMMA.
