Abstract
Recently, the fiber-reinforced composite materials have been widely used for structural applications due to their superior mechanical properties. The structural applications require a method to join the components of the system. Due to the ease of fabrication and installation, adhesively bonded joint receives particular attention in recent years. In the current study, damping and vibration characteristics of glass fiber-reinforced composite laminated materials have been investigated with respect to the bonded length of adhesively single strap joint type. The experimental studies were performed using six symmetric laminates having fiber orientation angle at four different bonded length. The vibration characteristics of the composite laminates were determined by dynamic modal analysis. The damping properties were obtained using half power bandwidth method from the results taken vibration response curves. The obtained results were compared with original laminates.

Yapıştırma ile Birleştirilmiş Cam Elyaf Takviyeli Kompozit Tabakaların Sönümleme ve Titreşim Davranışları
Abstract
Son zamanlarda, elyaf takviyeli kompozit malzemeler üstün mekanik özelliklerinden dolayı yapısal uygulamalarda yaygın olarak kullanılmaktadır. Yapı bileşenlerinin sisteme dahil olması için bir yöntem gerekmektedir. Son yıllarda yapıştırma ile birleştirme yöntemi üretim ve kurulum kolaylığından dolayı dikkat çekmektedir. Bu çalışmada cam elyaf takviyeli kompozit tabakalı plakaların sönümleme ve titreşim davranışları tek takviyeli bindirme bağlantısı kullanılarak birleşim uzunluğuna göre araştırılmıştır. fiber yönelimlerine sahip altı simetrik tabakadan oluşan plakalar dört farklı birleşim uzunluğunda deneysel olarak incelenmişlerdir. Kompozit plakaların titreşim özellikleri dinamik model analizi yapılarak belirlenmiştir. Sönümleme özellikleri titreşim tepkisi eğrilerinden alınan sonuçların yarım bant genişlik yöntemini kullanmak sureti ile elde edilmiştir. Elde edilen sonuçlar birleştirme yapılmamış kompozit tabaka ile karşılaştırılmıştır.
