KOMPOZİT MALZEMELERİN CHARPY DARBE TESTİ SONRASI ULTRASONİK C-SCAN YÖNTEMİ İLE HASAR ANALİZİ

Bu çalışmada, elyaf takviyeli kompozitlerde darbe sonrası absorblanan enerji ile oluşan iç hasar görüntüsü araştırılmıştır. 14 kat karbon ve 14 kat cam kumaştan oluşturulan kompozit yapılarda matris malzeme değişkeni sabit tutularak vakum infüzyon yöntemi ile numuneler aynı boyutlarda üretilmiştir. Üretilen bu numuneler Charpy darbe test cihazı ile darbeye maruz bırakılmıştır. Numunelere darbe öncesinde ve sonrasında doğrudan geçişli ultrasonik test (TTU) yöntemine göre muayene yapılmıştır. Elde edilen C-Tarama görüntülerinde görüntü işleme yöntemi kullanılarak, oluşan iç hasar alanı hesaplanmıştır. Sonuç olarak; Charpy test cihazından alınan enerji absorblama oranı ile hasar yayılımı ve hasarlı bölgenin kapladığı alan arasında doğru orantı tespit edilmiştir.
