Özet:

 In this study, particles obtained from walnut and hazelnut shells, which are lignocellulosic agricultural wastes, were used as reinforcement in the production of composite materials. After the grinding and sieving processes, the shells were subjected to heat treatment in order to remove the moisture from their content. Then, surface modification processes were carried out with the alkalization method. Four different composite samples with both walnut and hazelnut shell fillings were produced as neat polymer, untreated, heat-treated, and surface-modified reinforcement. The samples were subjected to hardness and tensile tests, and their mechanical behaviors were determined. Then, wear tests were carried out on the ball-on-flat device. Weight loss and friction coefficient data were obtained as a result of the wear tests. In addition, wear marks were examined morphologically with SEM and EDX analysis methods. As a result of the study, it was determined that the surface modification process increased the mechanical and tribological performance for both fillers. This shows that surface modification processes must be carried out before using lignocellulosic agricultural wastes as reinforcement.

 Bu çalışmada, lignoselülozik tarımsal atık olan ceviz ve fındık kabuklarından elde edilen parçacıklar kompozit malzeme üretiminde takviye olarak kullanılmıştır. Öğütme ve eleme işlemlerinin ardından kabuklar, içeriğindeki nemin uzaklaştırılması amacıyla ısıl işleme tabi tutuldu. Daha sonra alkalizasyon yöntemi ile yüzey modifikasyon işlemleri gerçekleştirilmiştir. Ceviz ve fındık kabuğu dolgulu; saf polimer, işlemsiz, ısıl işlemli ve yüzey modifikasyon işlemli olarak dört farklı kompozit numune üretilmiştir. Numunelere sertlik ve çekme testleri uygulanarak mekanik davranışları belirlenmiştir. Daha sonra ball-on-flat cihazında aşınma testleri gerçekleştirilmiştir. Aşınma testleri sonucunda ağırlık kaybı ve sürtünme katsayısı verileri elde edilmiştir. Ayrıca aşınma izleri SEM ve EDX analiz yöntemleri ile morfolojik olarak incelenmiştir. Çalışma sonucunda, yüzey modifikasyon işleminin her iki dolgu malzemesi için de mekanik ve tribolojik performansı artırdığı belirlenmiştir. Bu durum, lignoselülozik tarımsal atıkların takviye olarak kullanılmasından önce mutlaka yüzey modifikasyon işlemlerinin gerçekleştirilmesi gerektiğini göstermektedir.
