Cam Küre Takviyeli Polipropilen Kompozit Malzemelerin Delaminasyon Faktörünün Deneysel Olarak İncelenmesi

Bu çalışmada, cam küre takviye fazlı polimer matrisli kompozit malzemenin delinmesi sonucu ortayaçıkan delaminasyon faktörünün etkileri deneysel olarak incelenmiştir. Takviye fazı olarak ağırlıkça %5,%10 ve %20 takviye oranında cam küre kullanılmıştır. Matris malzemesi olarak Polipropilen tercihedilmiştir. Elde edilen sonuçlara göre, kesme hızı ve ilerleme arttıkça delaminasyon miktarındayükselmeler meydana gelmiştir. Elde edilen en düşük delaminasyon miktarı (1.18) 0.05 mm/devirilerleme ve 15m/dk kesme hızında karbür takım türü ile elde edilmiştir. Ayrıca, kompozit içerisindekitakviye miktarı arttıkça delaminasyon faktörünün de yükseldiği saptanmıştır. En düşük delaminasyonmiktarı %5 cam küre takviye içeren kompozit malzemede olmuştur.

Experimental Investigation of Delamination Factor of Glass Sphere Reinforced Polypropylene Composite Materials

In this study, the effect of delamination factor on glass-spherical reinforced polymer composite material was investigated. Glass sphere was used as reinforcement phase with a reinforcement rate of 5%, 10% and 20% by weight. Polypropylene is preferred as matrix material. According to the results, there was an increase in the amount of delamination as the cutting speed and feed rate increased. The lowest amount of delamination (1.18) was obtained in carbide tool type with 0.05 mm/rev feed and 15 m/min cutting speed. Also, it was found out that the amount of reinforcement in the composite increased as the amount of the delamination factor increased. The lowest amount of delamination was in composite material containing 5% glass sphere reinforcement.
