“…For this reason, many works have been carried out to improve the adhesion properties between substrate and adhesives taking into account different methods. Sarac et al 9 used Al 2 O 3 nanoparticles to increase the mechanical properties and improve the failure surfaces, switching from adhesive to adhesive/cohesive failures. Adin et al 10,11 and Kurtkan et al 12 showed different strategies to increase the mechanical properties of an adhesive joint by modifying the sizes of the substrates (thickness and width) and the bonding area.…”

Plasma treatment has been used in recent years to activate the surfaces of adhesive substrates and thus as an adhesion promoter between adhesive and substrates. The use of plasma treatments is widely adopted in the automotive industries especially for polymers that present low surface energy, such as polypropylene. In this work, polypropylene substrates used in the automotive industries have been treated with two different techniques: vacuum and atmospheric plasma. Then, polyurethane and methacrylate adhesives have been used to bond single lap joints (SLJs). Typically, these two adhesives cannot bond polypropylene substrates without surface treatments. An experimental plan has been designed to investigate the process parameters that can increase the functional polar groups (FPGs) maximizing the adhesion strength. Besides the types of plasma, two different gas carriers (air and nitrogen) and different treatment times have been investigated. The substrates, treated and not treated, have been assessed through scanning electron microscopy, energy-dispersive X-ray analysis, and Fourier-transform infrared spectroscopy to quantitatively assess the increment of FPGs after the different treatments. The experimental plan shows that the atmospheric plasma can improve the surface of the substrates by using a smaller time. Mechanical tests on SLJs show that methacrylate and polyurethane cannot bond polypropylene substrates without the plasma treatment. On the other hand, the treated substrates can form a strong bonding with the adhesive since all SLJs exhibit a substrate failure. Mechanical tests have been also carried out after three different aging cycles showing that the adopted plasma treatment is not affected by the aging cycles.

Bu çalışmada, yapıştırma bağlantıların mukavemeti üzerine normal ve kayma gerilmelerinin etkilerini daha iyi anlamak üzere koniklik açısının değişimi ile ara yüzeyde oluşacak normal ve kayma gerilmelerin değiştiği uç uca konik yapıştırma bağlantı geometrisi incelendi. Alüminyum ve yapı çeliği olmak üzere yapıştırılan iki malzeme farklı açılarda konik yapıştırma yüzeyleri DP810 yapısal yapıştırıcı kullanılarak elde edilen uç uca bağlantının (butt joint) sayısal analizi yapıldı. Analizlerde von Mises akma ve kırılma kriteri kullanılarak bağlantıların aynı yapışma yüzeylerine karşılık farklı açılar için hasar yükleri belirlendi. Ayrıca aynı yüke karşılık bütün yapışma yüzeyleri için gerilme dağılım grafikleri elde edilerek mukayeseleri yapıldı. Konik bağlantı geometrisinde açı ve çap değeri arttıkça bağlantının hasar yükleri artmıştır.

“…On the other hand, introducing nanomaterials in polymers can endow the original polymers with multifunctional or strengthening properties for high-performance applications, − which potentially provides a clue to prepare reinforced adhesives with an acceptable level of mechanical properties for bonding applications. Several research groups have studied adhesive strengths and fatigue lifetimes of epoxy nanocomposite adhesives and found improved adhesion performance by introducing even low loading content of various nanofillers. ,− …”

Organoclay, such as organo-modified montmorillonite (MMT), is one of the potential filler candidates in the preparation of epoxy nanocomposite adhesives for automotive and civil engineering industries. However, there is no systematic research on the effect of organoclay reinforcement on its adhesion and fatigue behaviors in shear loading. Here, single-lap joints (SLJs) of stainless steel substrates bonded with epoxy/MMT nanocomposite adhesives, consisting of diglycidyl ether of bisphenol A and poly(oxypropylene) diamine with various weight contents of a commercialized MMT filler, were prepared. The dispersity of MMT and bulk mechanical properties were investigated by wide-angle X-ray scattering/ diffraction, the uniaxial tensile test, and dynamic mechanical analysis. The lap shear strengths and failure modes were investigated based on the single-lap shear test, and the joint durability was examined by using the fatigue test with various shear stress levels. Through the incorporation of the MMT fillers in epoxy resins, the lap shear strengths increased from 25 to 40 MPa, the failure modes changed from adhesive failure mode to cohesive one, and the fatigue lifetimes prolonged with the addition of a small amount of MMT.
