Bu çalışmada yüksek yoğunluklu polietilen (YYPE) ve % 40-70
aralığında değişen oranlarda odun lifi kullanılarak odun plastik kompozit (OPK)
malzemeler üretilmiştir. Üretilen bu malzemelerin çekme direnci, eğilme
direnci, elastikiyet modülü ve şok direnci gibi mekanik özelliklerine lif
oranın etkisi araştırılmıştır. Ayrıca bağlayıcı ajan etkisinin araştırılması
için en düşük ve en yüksek odun katkı oranlarına sahip malzemeye maleik
anhidrit ile muamele edilmiş polietilen (MAPE) eklenmiştir. Kompozit örnekleri
laboratuvar tipi ikiz vidalı ektrüder kullanılarak üretilmiştir ve sıcak presle
kalıplama yöntemi ile test levhaları hazırlanmıştır. Sonuçlar göre bağlayıcı
ajan olmayan örnek grupları için genel anlamda kompozit malzeme içeriğindeki
odun lifi oranının artması mekanik özelliklerdeki eğilme, çekme ve şok
dirençlerini azaltırken elastikiyet modülü değerlerini artırmıştır. Ancak
malzeme içeriğine bağlayıcı ajan MAPE eklenmesi mekanik özellikleri önemli
ölçüde iyileştirmiş. Özellikle %70 odun lifi ve MAPE içeren kompozit örnekler,
bağlayıcı içermeyen tüm örnek gruplarından daha iyi mekanik sonuçlar
göstermiştir. Sonuç olarak, bu çalışma ile yüksek lif oranı ile düşük
maliyetli, hafif ve estetik görünüme ve aynı zamanda iyi mekanik özelliklere
sahip OPK malzemelerin üretilebileceği gösterilmiştir.

Investigation of the effect of high-fibrous filling material on the mechanical properties of wood plastic composites

Öz

In this study, wood plastic composite (WPC) materials were
produced using high density polyethylene (HDPE) and wood fiber at various
ratios ranging from 40% to 70%. The effects of fiber content on mechanical
properties such as tensile strength, bending strength, elasticity modulus and
shock resistance of these materials were investigated. In addition, maleic
anhydride grafted polyethylene (MAPE) was also added to the materials, which
had lowest and highest wood fiber additive, to investigate the effect of the
binding agent effect. Composite samples were produced via a laboratory type
twin screw extruder and test panels were prepared using hot press molding
method. According to the results, the bending, tensile and shock resistances
generally decreased with the increasing ratio of wood fiber in the composite
material content while modulus of elasticity 
increased for the sample groups without coupling agent. However, the
addition of the coupling agent MAPE into the material content significantly
improved the mechanical properties. Especially, the addition of MAPE provided
better resistance values than all sample groups without MAPE even for the
samples containing 70% wood fiber. As a result, with this study, it has been
shown that WPC materials with low cost, light weight, aesthetic appearance and
good mechanical properties as well could be produced with high fiber ratio.
