In this study, shear tests results of single lap adhesive joints with Aluminum 5754 are included. To investigate the effect of closed-hole drilling on adhesive-bonded joints, different types of connection configurations were created by drilling holes in the surfaces of the aluminum. When holes are drilled into one of the aluminum parts in the joint, there was a 39% increase in the failure load of the joints using Araldite 2015 compared to both without holes aluminum. The increase in the failure load on joints using Araldite AV138 was 54%. When holes are drilled into both aluminum parts in the joint, there was a 98% increase in the failure load of the joints using Araldite 2015 compared to both without holes aluminum. The increase in the failure load on joints using Araldite AV138 was 165%. In addition, the elongation amounts in the shear tests of the samples using Araldite 2015 were higher than the samples using Araldite AV 138.

Kör delik delmenin alüminyum 5754 ile oluşturulan tek bindirmeli yapıştırma bağlantıların kayma dayanımına etkisi

Öz

Bu çalışmada, Alüminyum 5754 ile oluşturulan tek bindirmeli yapıştırma bağlantıların kayma test sonuçlarına yer verilmiştir. Kapalı delik delme işleminin yapıştırıcı ile birleştirilmiş bağlantılar üzerindeki etkisini araştırmak amacıyla alüminyumların yüzeylerine delikler delinerek farklı tipte bağlantı konfigürasyonları oluşturulmuştur. Bağlantıdaki alüminyum parçalardan biri delikli olduğunda, Araldite 2015 kullanılan bağlantıların hasar yükünde, her ikisi de deliksiz alüminyumlara göre %39 artış görülmüştür. Araldite AV138 kullanılan bağlantılardaki hasar yükünde ise artış %54 olmuştur. Bağlantıdaki alüminyumlardan ikisi de delikli olduğunda, Araldite 2015 kullanılan bağlantılardaki hasar yükünde, her ikisi de deliksiz alüminyumlara göre %98 artış görülmüştür. Araldite AV138 kullanılan bağlantılardaki hasar yükünde ise artış %165 olmuştur. Ayrıca, Araldite 2015 kullanılan numunelerin kayma testlerindeki uzama miktarları Araldite AV 138 kullanılan numunelere göre daha yüksek çıkmıştır.
