Erimiş Filament Üretim Yöntemi ile Üretilen Kompozit Yapılarda Yöne Bağlı Yüzey Özelliklerinin İncelenmesi ve İyileştirilmesi

Öz

Prototip üretmenin ötesinde nihai ürün üretiminde de kullanılmaya başlanan eklemeli imalat yöntemleri günümüzde popüler araştırma konularıdır. Kullanım alanı ve kullanıcı kitlesi daha geniş olan Erimiş Filament İmalatı (FFF) yöntemi bu yöntemler arasında en bilinenidir. Polimerin katmanlar halinde ekstrüde edildiği yöntemin tasarım özgürlüğü ve topoloji optimizasyonu gibi avantajlarının yanı sıra yüzey pürüzlülüğü ve düşük üretim hızı gibi dezavantajları da vardır. FFF yönteminde kullanılabilecek malzeme sayısı gün geçtikçe çeşitlenmekte ve saf polimerlerin ötesinde polimerik kompozitler de üretilebilmektedir. Bu üretim yönteminde poliamid gibi mühendislik polimerlerinin kullanılması birçok yeni fırsat yaratmaktadır. Ayrıca kısa elyaf takviyeli polimerik kompozitlerin üretimine başlanması, yüksek performanslı nihai ürünlerin üretilmesinin önünü açmıştır. Bu çalışmada poliamid ve kısa karbon fiber takviyeli polimer matrisli kompozit malzemeler kullanılarak üretilen numunelerin yüzey pürüzlülüğüne katman kalınlığı ve baskı yönü gibi parametrelerin etkisi incelenmiştir. Yüzey pürüzlülüğünü iyileştirmek için 3D baskılı numunelerin yüzeylerine kimyasal yüzey işlemi uygulandı. Tabaka kalınlığının artmasının yüzey pürüzlülüğünü arttırdığı, -/+45 dolgu oryantasyonunun 0 ve 90 oryantasyonlarına göre daha yüksek pürüzlülük oluşturduğu, kimyasal yüzey modifikasyonu ile yüzey kalitesinin arttırılabileceği sonucuna varılmıştır.

Examination and Improvement of Direction-Dependent Surface Properties in Composite Structures Produced by the Fused Depostion Modelling Method

Öz

Additive manufacturing methods, which have begun to be used in final product production beyond producing prototypes, are popular research topics today. The Fused Filament Fabrication (FFF) method, which has a wider usage area and user base, is the most well-known among these methods. The method in which the polymer is extruded in layers has advantages such as design freedom and topology optimization, as well as disadvantages such as surface roughness and low production speed. The number of materials that can be used in the FFF method is diversifying day by day, and polymeric composites can also be produced beyond pure polymers. The use of engineering polymers such as polyamide in this production method creates many new opportunities. In addition, the start of production of short fiber reinforced polymeric composites has paved the way to produce high-performance final products. In this study, the effects of parameters such as layer thickness and printing orientation on the surface roughness of samples produced using polyamide and short carbon fiber reinforced polymer matrix composite materials were examined. Chemical surface treatment was applied to the surfaces of 3D-printed samples to improve surface roughness. It was concluded that the increase in layer thickness increases the surface roughness, the -/+45 filling orientation creates higher roughness than the 0 and 90 orientations, and the surface quality can be increased by chemical surface modification.
