Sac Malzeme Yüzey Pürüzlülüğünün Fiber-Metal Tabakalı Kompozitlerin Mekanik Özelliklerine Olan Etkisi

Fiber-metal tabakalı kompozitlerin kullanımının özellikle havacılık gibi endüstrilerde giderek yaygınlaşmasıyla bu tür malzemelerin mekanik performanslarının incelenmesi de oldukça önemli hale gelmiştir. Matris ve takviye malzemesinin özelliklerinin, operatör tecrübesinin ve üretim yönteminin nihai ürünün kullanım performansı üzerinde doğrudan etkisinin olduğu bilinmektedir. Bu çalışma da yüzeyi 60, 220 ve 600 kum zımpara ile mekanik olarak farklı pürüzlülük değerlerinde işlenen 1050 serisi alüminyum sac malzeme, cam elyaflarla tabakalı kompozit olarak üretilmiş ve mekanik özellikleri incelenmiştir. Buna göre numunelerin çekme, üç nokta eğilme ve tabakalar arası kayma gerilmesi değerleri ölçülmüş ve hasar durumları makro görüntüler üzerinden değerlendirilmeye çalışılmıştır. Elde edilen sonuçlara göre yüzey pürüzlülüğü arttıkça mekanik dayanım da artmaktadır. Bu çalışma ile fiber-metal tabakalı kompozitlerin yeni kullanım alanları ve tasarım parametreleri ile ilgili önemli sonuçlar elde edilmiştir.

The Effect of Sheet Material Surface Roughness on Mechanical Properties of Fiber-Metal Laminated Composites

With the increasing use of fiber-metal laminated composites, especially in aerospace industries, it has become vital to examine the mechanical performance of these materials. It is known that the properties of the matrix and the reinforcement material, the experience of the operator, and the production method have a direct effect on the usage performance of the final product. In this study, the 1050 series aluminum sheet materials, which are mechanically pre-treated with 60, 220, and 600 grit of sandpaper in different roughness values, were produced as a fiber-metal laminated composite with glass fibers, and its mechanical properties were investigated. Accordingly, the tensile, three-point bending and interlaminar shear strength values of the samples were measured, and the damage conditions were evaluated by macro imaging. According to the results, the mechanical strength improved when the sur-face roughness increased. This study has achieved significant outcomes regarding the new usage areas and fiber-metal laminated composites' design parameters.
