Özet

Kompozit malzemelerin havacılık, savunma, otomotiv ve enerji gibi ileri mühendislik alanlarında giderek daha yaygın kullanılması, bu yapıların servis ömrü boyunca güvenilir bir şekilde değerlendirilmesini zorunlu hâle getirmiştir. Üretim süreçleri veya kullanım koşulları sonucunda kompozitlerde delaminasyon, gözeneklilik, lif kırılması ve ara yüzey ayrılması gibi çeşitli iç kusurlar oluşabilmekte ve bu kusurların yapısal bütünlüğe zarar vermeden tespit edilmesi için tahribatsız muayene (NDT) yöntemleri kritik önem taşımaktadır. Ultrasonik test teknikleri, yüksek çözünürlükleri ve kompozitlerin heterojen yapısına uyum sağlayabilmeleri nedeniyle NDT yöntemleri içinde öne çıkan bir konuma sahiptir. Bu çalışmada, kompozit malzemelerin ultrasonik muayenesinde yaygın olarak kullanılan Pulse-Echo (PEUT) ve Through-Transmission (TTU) yöntemleri ile faz kontrollü çok elemanlı prob yapısına dayanan Phased Array Ultrasonic Testing (PAUT) literatüre dayalı olarak sistematik biçimde karşılaştırılmıştır. Yöntemler; tespit edilebilir kusur türleri, görüntüleme performansı, uzaysal çözünürlük, ekipman gereksinimleri ve endüstriyel uygulanabilirlik açısından değerlendirilmiştir. Bulgular, PEUT’un tek yüzeye erişim avantajı sayesinde yüzeye yakın kusurların hızlı tespitinde etkili olduğunu; TTU’nun özellikle hacimsel hasarların belirlenmesinde yüksek duyarlılık sağlayabildiğini; PAUT’un ise çoklu açılı tarama ve odaklama kabiliyetleri ile karmaşık kusurların karakterizasyonunda üstün görüntüleme imkânı sunduğunu göstermektedir. Sonuç olarak, bu yöntemlerin tek başına tüm kusur türlerini kapsayıcı olmadığı, kompozit yapılarda çoğu durumda birbirini tamamlayıcı nitelikte kullanıldığı anlaşılmaktadır.
