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

Abstract

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.

Effect of adhesive thickness and loading speed on bonding strength in single-lap adhesive joints with aluminum 5754-H111

Abstract

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.
