“…This might be attributed to the rigidity of the structure, which led to increase the abrasive wear between the samples and counterparts. This result consistent with previous study findings found in the literature, [22][23][24] which claim that abrasive wear resistance of polymer composites might not proportional to the rigidity or fiber content of the composites all the time. Also it is accepted that the wear rates of polymers can be inversely proportional to their tensile stress and elongation at break values.…”

“…22 These factors are important especially in the case of abrasive wear which occurs when a hard surface or rigid particles slide on a softer material and create grooves on its surface, and can cause one million times more wear loss than adhesive wear. 3,6,23 It is generally expected that if the tensile strength and rigidity of polymers are increased due to the contribution of the reinforcements, their wear resistance should also increase. Several researchers have reported on the enhanced abrasive wear behavior of fiber-reinforced polymer composites compared to pristine polymers.…”

“…Several researchers have reported on the enhanced abrasive wear behavior of fiber-reinforced polymer composites compared to pristine polymers. 14,24,25 However, in some studies, the wear resistance of polymer composites is found to reduce even when the hardness and elastic modulus are increased, 22,24,26 which can be attributed to the specific mechanical properties of the worn material such as fatigue behavior, 23 or abrasive wear parameters such as applied normal load, sliding velocity or characteristics of abrasive material used, which all may enhance the repeated plowing effect on a rigid material. Tong et al 24 found that abrasive wear resistance of wollastonite fiber-reinforced ultra high molecular weight polyethylene (UHMWPE) composites is reduced as the fiber content exceeds the 10 wt.%.…”

This study puts forth the synergistic effect of fiber concentration and maleic anhydride-grafted polyethylene (PE-g-MA) compatibilization on the abrasive wear properties of high-density polyethylene (HDPE) composites. Composites including carbon, basalt, jute and coconut short fibers with different weight ratios were processed by melt blending and then tested by using a pin-on-disc abrasive wear tester in dry sliding conditions. The test rig was also equipped with a vacuum system, for the first time, to promote two-body abrasive wear of the composites by reducing the wear debris which may be trapped in the wear track and alter the wear properties. In addition, fiber and coupling agent concentrations and test parameters were investigated using L16 full-factorial experimental design and the relationships between these parameters and wear behaviors of the composites were analyzed on the basis of the findings. This work clearly shows that high rigidity obtained by fiber contribution was not beneficial from the abrasive wear resistance point of view, due to repeated plowing effect of the counterpart material under the test conditions. Nevertheless, basalt fiber-reinforced composites showed higher wear resistance than other composites. Except for coconut fibers, PE-g-MA exhibited good miscibility between fibers and matrix, and thus an enhancing effect on the hardness values, and also wear resistance of the samples. Briefly, the rigidity and miscibility of the composites were found in balance for optimum wear rates.

“…This correlation between the tensile and abrasive test is called the “Ratner–Lancaster correlation”. Based on this correlation, several authors have predicted and obtained composites and nanocomposites with high wear resistance [ 38 , 39 , 40 ]. This paper also supports that this correlation is a good strategy to achieve higher wear resistance of the polymer by adding fillers, increasing the ultimate tensile properties and not stiffness.…”

High-Tribological-Performance Polymer Nanocomposites: An Approach Based on the Superlubricity State of the Graphene Oxide Agglomerates

2021

Here, nanocomposites of high-molecular-weight polyethylene (HMWPE) and HMWPE-UHMWPE (80/20 wt.%) containing a low amount of multilayer graphene oxide (mGO) (≤0.1 wt.%) were produced via twin-screw extrusion to produce materials with a higher tribological performance than UHMWPE. Due to the high viscosity of both polymers, the nanocomposites presented a significant concentration of agglomerates. However, the mechanical (tensile) and tribological (volumetric loss) performances of the nanocomposites were superior to those of UHMWPE. The morphology of the nanocomposites was investigated using differential scanning calorimetry (DSC), microtomography, and transmission electron microscopy (TEM). The explanation for these results is based on the superlubricity phenomenon of mGO agglomerates. It was also shown that the well-exfoliated mGO also contained in the nanocomposite was of fundamental importance as a mechanical reinforcement for the polymer. Even with a high concentration of agglomerates, the nanocomposites displayed tribological properties superior to UHMWPE’s (wear resistance up to 27% higher and friction coefficient up to 57% lower). Therefore, this manuscript brings a new exception to the rule, showing that agglomerates can act in a beneficial way to the mechanical properties of polymers, as long as the superlubricity phenomenon is present in the agglomerates contained in the polymer.

Bu çalışmada misvak takviyeli kompozitlerin abrazif aşınma özellikleri incelenmiş ve yapısal parçalardan medikal uygulamalara kadar farklı sektörlerdeki kullanım potansiyeli araştırılmıştır. Matris malzemesi olarak 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 aşınma özellikleri üzerindeki etkileri araştırılmıştır. Önemli parametrelerin ve bu parametrelerin etkileşimlerinin tribolojik özellikler üzerindeki etkilerini analiz etmek için 2 3 tam eşlendirmeli deneysel tasarım yöntemi kullanılmıştır. Testler sonrası numunelerin aşınmış yüzey morfolojileri taramalı elektron mikroskopisi (SEM) ile incelenmiştir. Shore D sertlik ölçüm testleri de yapılarak bulgular ışığında bahsedilen özellikler arasındaki ilişkiler yorumlanmıştır. Aşınma test sonuçlarından sırasıyla; normal yük, misvak konsantrasyonu ve kayma hızının önemli parametreler olduğu tespit edilmiştir. Kompozitlerin aşınma oranlarının artan yük, misvak konsantrasyonu ve kayma hızı ile arttığı bulunmuştur. Bununla birlikte, düşük misvak konsantrasyonuna (%5-10) sahip kompozitlerin nispeten düşük aşınma oranları gösterdiği tespit edilmiştir. Shore D sertlik testi sonuçlarından, artan misvak oranı ile kompozit sertliğinin de arttığı bulunmuştur. Bilindiği üzere tribolojik ve mekanik özellikler her zaman uyumlu değildir. Bu durumun zımpara kâğıdının abrazif yapısından ve literatürde ilk kez kullanılan vakum üniteli aşınma sisteminin 2-elemanlı abrazif aşınmayı desteklemesinden kaynaklandığı düşünülmektedir.
