Özet:

 The objective of this study is to investigate the mechanical performance on develop flaxepoxy composite filled with montmorillonite nanoclay for lightweight applications. For this purpose, firstly, nanoclay at different weight percentages montmorillonite nanoclay such as 0.5, 1, 1.5 was dispersed homogeneously into epoxy resin with the help of ultrasanitization process. For better nanoclay distribution in composite, the montmorillonite nanoclay concentration higher than 1.5 was not analyzed. Secondly, using this mixture, flax fiber based composites were produced by vacuum bag molding process. Finally, the mechanical properties of flaxepoxy composites filled with different percentages montmorillonite nanoclay were determined with tensile, flexural, and in-plane shear test. From the experimental results obtained, the addition of montmorillonite nanoclay indicate positive effect on the performance of the composites compared with the neat composite samples, if the montmorillonite nanoclay distribute homogeneously in the epoxy. The composites added with 0.5 wt. nanoclay showed the highest tensile modulus and tensile strength. Moreever, the elasticity modulus of composite samples with 0.5 nanoclay addition is approximately 87 higher than the pure composite. Also, the composite samples loaded with 1.5 wt. of montmorillonite nanoclay performs better under flexural loading conditions.

 Bu çalışmanın amacı, hafiflik özelliği gerektiren uygulamalar için, montmorillonit nanokil ilave edilmiş keten fiber esaslı-epoksi kompozit malzemelerin mekanik performansını araştırmaktır. Bu amaca yönelik olarak, ilk olarak, 0,5, 1, 1,5 gibi farklı ağırlık yüzdelerinde montmorillonit nanokil, epoksi reçine içerisine ultrasanikasyon işlemi yardımıyla homojen bir şekilde dağılması gerçekleştirilmiştir. Epoksi reçine içerisine ilave edilen nanokil miktarı,daha iyi homojen karışım olması için 1,5 sınır değer olarak belirlenmiştir. İkinci olarak, bu karışım kullanılarak keten fiber esaslı kompozitler vakum poşet kalıplama yöntemi ile üretimi gerçekleşmiştir. Son olarak farklı yüzdelerde montmorillonit nanokil ile doldurulmuş ketenepoksi kompozitlerin mekanik özellikleri çekme, eğilme ve düzlem içi kayma testleri ile belirlenmiştir. Elde edilen deney sonuçlarında, eğer montmorillonit nanokilin epoksi içinde homojen bir şekilde dağılması durumunda, keten fiberliepoksi kompozit malzemenin mekanik peformansının nanokil katkısız kompozite göre iyileşme sağlandığı görülmüştür. Ağırlıkça 0,5 nanokil ilave edilen kompozitler en yüksek çekme modülünü ve çekme mukavemetini göstermişlerdir. Dahası, ağırlıkça 0,5 nanokil katkılı kompozit numunelerin elastisite modülü, katkısız kompozite göre yaklaşık 87 daha yüksek elde edilmiştir. Ayrıca, ağırlıkça 1,5 montmorillonit nanokil ile yüklenen kompozit numuneler, eğilme yükleme koşulları altında daha iyi performans göstermişlerdir.
