Özet
Yapıştırma bağlantılarında, yapıştırıcı içerisine katılan nanopartiküllerin,
bağlantıların mekanik özelliklerine etkisi ile ilgili araştırmalar son zamanlarda
dikkat çekmektedir. Bu çalışmada; epoksi yapıştırıcı içerisine % 2 oranında Al2O3
nanopartikül katılarak ve katkısız epoksi yapıştırıcı kullanılarak tek tesirli
bindirme bağlantıları oluşturulmuş ve bağlantıların mekanik özellikleri çekme yükü
altında 20 mm, 25 mm ve 30 mm bindirme boylarında deneysel olarak
incelenmiştir. Deneysel çalışmalarda DP460 epoksi yapıştırıcısı, Al2O3
nanopartikülleri ve yapıştırılan malzeme olarak St-37 çeliği kullanılmıştır.
Deneylerden elde edilen sonuçlar incelendiğinde; % 2 Al2O3 nanopartikül katkılı
yapıştırıcıların kullanılmasıyla 20 mm ve 30 mm bindirme boylu bağlantılarda
genel olarak hasar yükü azalmıştır. Ancak 25 mm bindirme boyunda % 5 oranında
bir artış görülmüştür. Ayrıca nanopartikül ilavesi bağlantıların uzama
kapasitelerine azaltıcı yönde etki yapmıştır.
There is a considerable interest nanoparticles added structural adhesives, recently. Because, nanoparticles improve the mechanical properties of an adhesive and its joint. In this paper, the static strengths of adhesive joints incorporating Al2O3 nanoparticles (% 2 proportions in epoxy adhesive) were compared to those adhesive joints without nanoparticles. Experiments were performed 20 mm, 25 mm and 30 mm overlap lengths, respectively. DP460 epoxy adhesive, Al2O3 nanoparticles and St-37 plates were used for the single lap adhesive joints. The results of the experimental research revealed that average tensile failure load was decreased in the 20 mm and 30 mm overlap bonded joints with nanoparticlereinforced adhesive. However, average tensile failure load was increased (% 5 proportions) in the 25 mm overlap bonded joints with nanoparticle-reinforced adhesive. Moreover, the extension capacity in the joints was decreased in the joints with nanoparticle-reinforced adhesive
