Abstract

In this work, abrasive wear properties of miswak reinforced composites were studied to get an inspiration about their availability for diverse applications from mechanical to medical parts. Polypropylene (PP) matrix and a maleic anhydride-grafted polypropylene (PP-g-MA) copolymer as coupling agent were used. Composites with different miswak concentrations (5, 10, 20 and 30% wt.) were characterized primarily by pin-on-disc test using abrasive sandpaper as counter material. The effect of the concentration of the miswak, normal load (2.5-5 N) and sliding velocity (60-72 rpm) on the wear properties of the composites were characterized. A 2 3 full-factorial experimental design was chosen to screen the significant factors and their interactions influencing the tribological performance of the composites. After the tests, the morphology of the worn surface of the samples was observed using scanning electron microscopy (SEM). Shore D hardness tests were also conducted and the relationships between these behaviours were analyzed on the basis of the findings. According to the wear test results, the factors that have the greatest effect on the wear rates are as follows: Normal load, miswak concentration and sliding velocity, respectively. The wear rate of the composites increases by increasing the normal load, miswak concentration and sliding speed. Nevertheless, composites with low miswak concentration (5-10% wt.) exhibited relatively less wear rates. In the case of Shore D harness values, an increase was observed with increasing the miswak concentration. It is well known that tribological and mechanical behaviours do not complement each other all the time. This is thought to be related to the abrasive nature of the sandpaper and promoting 2-body abrasive wear by the vacuum system of the test rig, which is the first in the literature.

Özet

Bu çalışmada misvak takviyeli kompozitlerin abrazif aşınma özellikleri incelenmiş ve yapısal parçalardanmedikal uygulamalara kadar farklı sektörlerdeki kullanım potansiyeli araştırılmıştır. Matris malzemesiolarak polipropilen (PP) ve uyumlaştırıcı ajan olarak da maleik anhidrit aşılı polipropilen (PP-g-MA)kopolimeri kullanılmıştır. Farklı konsantrasyonlardaki (ağ. %5, 10, 20 ve 30) misvak takviyeli kompozitler,abrazif bir zımpara kâğıdının karşı disk olarak kullanıldığı bir pin-on-disk sisteminde test edilmiştir.Misvak konsantrasyonu, normal yük (2.5-5 N) ve kayma hızının (60-72 dev/dak) kompozitlerin aşınmaözellikleri üzerindeki etkileri araştırılmıştır. Önemli parametrelerin ve bu parametrelerin etkileşimlerinintribolojik özellikler üzerindeki etkilerini analiz etmek için 2 3 tam eşlendirmeli deneysel tasarım yöntemikullanılmıştır. Testler sonrası numunelerin aşınmış yüzey morfolojileri taramalı elektron mikroskopisi(SEM) ile incelenmiştir. Shore D sertlik ölçüm testleri de yapılarak bulgular ışığında bahsedilen özelliklerarasındaki ilişkiler yorumlanmıştır. Aşınma test sonuçlarından sırasıyla; normal yük, misvakkonsantrasyonu ve kayma hızının önemli parametreler olduğu tespit edilmiştir. Kompozitlerin aşınmaoranlarının artan yük, misvak konsantrasyonu ve kayma hızı ile arttığı bulunmuştur. Bununla birlikte,düşük misvak konsantrasyonuna (%5-10) sahip kompozitlerin nispeten düşük aşınma oranları gösterdiğitespit edilmiştir. Shore D sertlik testi sonuçlarından, artan misvak oranı ile kompozit sertliğinin de arttığıbulunmuştur. Bilindiği üzere tribolojik ve mekanik özellikler her zaman uyumlu değildir. Bu durumunzımpara kâğıdının abrazif yapısından ve literatürde ilk kez kullanılan vakum üniteli aşınma sisteminin 2-elemanlı abrazif aşınmayı desteklemesinden kaynaklandığı düşünülmektedir.
