This study provides shear test results of single-lap adhesive joints with aluminum 5754-H111. To investigate the effect of adhesive thickness on joint strength in single-lap adhesive joints, three different thicknesses (0.2, 1, and 2 mm) were applied. Increasing the adhesive thickness from 0.2 mm to 1 mm and from 0.2 mm to 2 mm resulted in a reduction in shear load of roughly 36% and 44%, respectively. It has been observed that the joint strength decreases with increasing adhesive thickness in single-lap adhesive joints with aluminum 5754-H111. In addition, single-lap adhesive joints were tested at various loading rates (1, 10, and 100 mm/min), and the influence of loading speed on adhesive strength was studied. The shear load increased with the loading speed in the test results of single-lap adhesive joints.

Alüminyum 5754-H111 ile oluşturulan tek bindirmeli yapıştırma bağlantılarında yapıştırıcı kalınlığı ve yükleme hızının yapışma dayanımına etkisi

Öz

Bu çalışma, alüminyum 5754-H111 ile oluşturulan tek bindirmeli yapıştırma bağlantılarının kayma testi sonuçlarını sunmaktadır. Tek bindirmeli yapıştırma bağlantılarında yapıştırıcı kalınlığının bağlantı mukavemeti üzerindeki etkisini araştırmak için üç farklı kalınlık (0.2, 1 ve 2 mm) uygulanmıştır. Yapıştırıcı kalınlığının 0.2 mm'den 1 mm'ye ve 0.2 mm'den 2 mm'ye arttırılması, kayma yükünde sırasıyla yaklaşık %36 ve %44'lük bir azalmaya neden olmuştur. Alüminyum 5754-H111 ile oluşturulan tek bindirmeli yapıştırma bağlantılarında yapıştırıcı kalınlığı arttıkça bağlantı mukavemetinin azaldığı görülmüştür. Ayrıca, tek bindirmeli yapıştırma bağlantıları çeşitli yükleme hızlarında (1, 10 ve 100 mm/dk) test edilmiş ve yükleme hızının yapışma dayanımına etkisi araştırılmıştır. Tek bindirmeli yapıştırma bağlantılarının test sonuçlarında, kayma kuvveti yükleme hızıyla birlikte artmıştır.
