Abstract
Today studies on the recycling of
waste materials increasingly gaining importance and increasing with the growing
sensitivity to the environment. In this study, the changes in the mechanical
properties of composite materials produced by adding the black pine sawdust
with the polypropylene polymer matrix at different ratios were investigated. For the
production of composite, black pine saw dust mixed with PP polymer and then,
they were converted into pellets using twin-screw extruder and combined
pelletizer. The obtained pellets were molded into composite boards in 250 x 250
x 2 mm dimensions via hot press molding technique. Then tensile, bending and
impact resistance tests of composite boards produced were carried out according
to ASTM standards. According to the results of the mechanical tests, the
highest tensile strength value was found for the composite sample of 10% wood
flour loaded composite, while the highest bending strength was found for the
composite with 50% wood flour. In addition, the highest impact resistance was
obtained for the 20% wood flour added sample among all composites.

Abstract
Günümüzde
çevreye olan duyarlılıktaki artış ile birlikte atık maddelerin geri
dönüştürülebilme konuları üzerine araştırmalar yapılmaktadır. Bu çalışmada polipropilen (PP) polimer matrise ilave edilen farklı oranlardaki karaçam testere talaşından elde
edilen kompozit malzemelerin mekanik özelliklerindeki değişiklikler incelenmiştir.
Kompozit üretimi için karaçam testere talaşı ile PP polimer matrisi çift
burgulu ekstruder kullanılarak kompozit pelletleri formuna dönüştürülmüştür.
Elde edilen pelletlerden sıcak pres kalıplama tekniği ile 250x250x2 mm
ebatlarında kompozit levhalar üretilmiştir. Daha sonra üretilen kompozit
levhaların ASTM standartlarına göre çekme, eğilme ve darbe direnci testleri
yapılmıştır. Mekanik test sonuçlarına göre en yüksek çekme direnci değeri %10
odun unu ilaveli kompozit örneğinde, en yüksek eğilme direnci ise %50 odun unu
ilaveli kompozit örneğinde tespit edilmiştir. Ayrıca kompozitler arasında en
yüksek darbe direnci, %20 odun unu ilaveli kompozit örneğinde elde edilmiştir.
