Investigation of mechanical behavior of wood polymer nanocomposites (WPNs) samples using static vickers microhardness tester
Öz: Aim of study: In this study, XRD and Vickers microhardness analyses of wood polymer nanocomposites (WPNs) materials are carried out in detail. Especially, we are focused on the mechanical analysis.Area of study: Pine wood flour (40 mesh) as lignocellulosic filler obtained from a commercial WPC manufacturer (sema wood) in Tekirdag, Turkey are used.Material and Methods: Polypropylene, nano TiO2 and coupling agent are used in the experiments.Depending on the nanocomposite groups, granulated polymer, wood flour, nano TiO2 and MAPP are mixed.Then this mixture is compounded in a laboratory scale twin-screw extruder at 40 rpm screw speed.Main results: According to the obtained hardness results, all of the materials show RISE (Reverse Indentation Size Effect) behavior. Experimental microhardness results are compared with the mathematical models (Meyer's law, Proportional sample Resistance (PSR), Elastic/Plastic Deformation (EPD) and Indentation-Induced Cracking (IIC) models) used in the microhardness analysis of materials in the literature and the most suitable model for microhardness values of materials was determined. According to the models, IIC model is the most suitable to determine the micromechanical properties.Research highlights: Structural and mechanical properties of WPNs materials are investigated. The increase in the microhardness values of the all sample depends on the increase of applied load. In addition, the microhardness values decrease with increased TiO2 concentration in the samples and microhardness values reach a saturation region at around 1.5 N for the samples.

Ahşap polimer nanokompozit (WPN) numunelerinin mekanik davranışlarının statik vickers mikro sertlik test cihazı kullanılarak incelenmesi
Öz: Çalışmanın amacı: Bu çalışmada, ahşap polimer nanokompozit (WPN) malzemelerinin XRD ve Vickers mikrosertlik analizleri detaylı bir şekilde gerçekleştirilmiştir. Özellikle mekanik analizler üzerine odaklanılmıştır. Çalışma alanı: Tekirdağ'da ticari bir WPC üreticisinden (Sema Ahşap) elde edilen lignoselülozik dolgu maddesi olarak çam kerestesi kullanılmıştır. Materyal ve Yöntem: Deneylerde polipropilen, nano TiO2 ve birleştirme maddesi kullanılmıştır. Nanokompozit gruplara bağlı olarak, granül haline getirilmiş polimer, odun unu, nano TiO2 ve MAPP karıştırılmıştır. Daha sonra bu karışım, 40 rpm'lik vida hızında laboratuar ölçekli çift vidalı bir ekstrüderde birleştirilmiştir. Temel Sonuçlar: Elde edilen sertlik sonuçlarına göre, tüm materyaller RISE (Ters Çentik Boyutu Etkisi) davranışını göstermektedir. Deneysel sonuçlar, literatürde malzemelerin mikrosertlik analizlerinde kullanılan matematiksel modeller (Meyer Kanunu, Orantılı Numune Direnci (PSR), Elastik/Plastik Deformasyon (EPD) ve Çentici Kaynaklı Yarılma (IIC) modelleri ile karşılaştırılmış ve en uygun model belirlenmiştir. Bu modellere göre, IIC modeli, malzemelerin mikromekanik özelliklerini belirlemek için en uygun modeldir. Araştırma vurguları: WPN'lerin yapısal ve mekanik özellikleri araştırılmıştır. Tüm numunenin mikrosertlik değerlerindeki artış uygulanan yükün artmasına bağlıdır. Ek olarak, numunelerde TiO2 konsantrasyonun artması ile mikrosertlik değerleri azalmakta ve yaklaşık 1.5 N'de doyma bölgesine ulaşmaktadır.
