Experimental Investigation of Low-Velocity Impact Response of Plain-Weave Glass/Epoxy Composites Reinforced with Carbon Nanotubes

Öz

The low-velocity impact (LVI) response of the plain-weave glass/epoxy laminated composites, which were reinforced with various contents of carbon nanotubes (CNTs) was performed using a drop-weight Fractovis Plus impact machine. The nanocomposite plates were fabricated using hand lay-up (HLU) method. The effect of carbon nanotube addition into the epoxy resin is examined. The influence of the nanocarbon contents on the impact response was achieved by using 1 wt%, and 1.25 wt%. The low-velocity impact responses of the nanocomposite plates were compared, and the effect of CNT on the damaged area after impact was also discussed. The fillers adding changes the low-velocity impact (LVI) response of the plain-weave glass/epoxy laminated composites. Experimental results clearly demonstrated that the samples fabricated by various contents of carbon nanotube (CNTs), have a bigger damage area and more penetration threshold than the control samples (neat). Moreover, the plates with 1 wt % carbon nanotubes have the highest reaction force.

Karbon Nano-Tüp Katkılı Düz Örgü Cam-Epoksi Kompozitlerin Düşük Hızlı Darbe Deneylerinin Deneysel Olarak İncelenmesi

Öz

Bu çalışmada, Çeşitli oranlarda karbon nanotüp katkılı düz örgü cam epoksi tabakalı kompozitlerin Fractovis Plus darbe cihazı ile düşük hızlı darbeye gösterdikleri tepki araştırılmıştır. Nanokompozit plaklar el yatırma yöntemi ile üretilmiştir. Epoksi reçine içerisine katılan karbon nanotüp etkisi incelenmiştir. Ağırlıkça %1 ve %1,25 oranları kullanılarak nanokarbon içeriğinin etkisi darbe üzerindeki etkisi elde edilmiştir. Nanokompozit plakların düşük hızlı darbe tepkileri karşılaştırıldı ve darbe deneyi sonrası hasar alanı üzerine CNT etkisi incelenmiştir. Eklenen dolgu maddeleri düz örgü cam/epoksi kompozitlerin düşük hızlı darbe tepkilerini değiştirdi. Sonuçlar çeşitli oranlarda CNT katkılı olarak üretilen numunelerin katkısız numuneye göre hem daha büyük hasar alanına hem de daha büyük penetrasyon eşik enerjisine sahip olduğunu göstermiştir. Ayrıca, ağırlıkça %1 CNT oranlı plaklar en yüksek reaksiyon kuvvetine sahiptir.
