Abstract:

The usage of adhesively bonded lap joints in industrial applications has been growing in recent years because of the numerous advantages compared to other joining processes such as fastening, welding, and riveting. For effective design of the adhesively bonded engineering lap joints, it is essential to govern the failure potential of a particular adhesive joint under a certain load causing some stress and strain. In this work, study has been carried out by the application of multiple adhesives along the bondline region of lap joint. The objective of this paper is to experimentally examine the

This kind of stresses are responsible for the occurrence of tearing or chipping in a joint. The very significant influence of adhesion in the impact-bonded adhesive joint was the reason for testing this parameter in joints made with adhesives with different Young’s modulus.

Abstract:

Manufacturers of adhesives for industrial use determine the strength of adhesive joints during shear tests. Most often, components made of the same material are joined. In contrast, the roughness of the surfaces to be joined results from the use of a specific surface treatment technology. In adhesive manufacturers’ recommendations for metal-to-metal joints, surface technologies can be found without specifying numerical requirements for roughness. Modern techniques for shaping the geometric accuracy of components allow the formation of determined irregularities on the surface, which are charact

Adhesive joints are an alternative method of joining elements. New adhesives achieve cohesion and adhesion strength comparable with plastics used for structural components and coatings. Bonding is faster, simpler and cheaper. For this reason, adhesive joints are increasingly replacing other types of connections.

In adhesive joints used in several industrial applications, the adherends’ bonding is made using an adhesive, which is usually an epoxy resin.

Thus, in recent years, effective steps have been made to replace these adhesives with ecological (green) ones.

The adhesive lap joints are extensively used in various engineering fields. Various methods were proposed to increase the strength of the lap joint. This paper presents the lap joint's characterization by applying three grades of adhesives in different material properties along the bond line.

This technique reduces the stress concentration at the joining ends, so the stress distribution becomes smoother. Finite element analysis is used to

At the cryogenic temperature, the detection of micro crack is important to estimate the fatigue life because the polymeric adhesives become very brittle.

Abstract:

Establishing a correlation between the nature of destruction and the strength of an adhesive joint has always aroused interest among both domestic and foreign researchers. Analysis of a number of publications suggests that such a dependence clearly exists, especially in simple systems that include adhesives of simple composition, substrates without pre-treatment and the absence of auxiliary materials that improve adhesion, for example, primers. As for complex systems with a large array of simultaneously analyzed experimental data, dependencies similar to those described above have not been ide

Abstract Chlorination of a thermoplastic styrene-butadiene-styrene rubber (S0) with a solution of 2 wt% trichloroisocyanuric acid (TCI) in ethyl acetate improved its adhesion to polyurethane adhesives. The analysis of the failed surfaces (obtained after T-peel test of S0/PU joints) showed that the locus of failure in the rubber/polyurethane joints progresses from adhesion (in non chlorinated-S0/PU joint) to cohesion in the chlorinated layer (for chlorinated-S0/PU joint). The composition of this chlorinated layer differed from the composition of the non bonded-chlorinated rubber, i.e. the failu

Abstract:

AbstractSteel constructions made of circular hollow sections are commonly joined by welding or ring‐flange bolting. An additional, novel joining method is the so‐called hybrid grouted joint. The hybrid grouted joint is characterised by its multi‐layered composition. In contrast to state‐of‐the‐art grouted joints, hybrid grouted joints include thin adhesive layers, which are applied on the steel surfaces prior to grouting. Sand grains are embedded in the yet uncured adhesive. After the curing of the adhesive, the surface has a high degree of roughness. This allows a high‐performance interlock b

Abstract:

Adhesive joints are some of the oldest inseparable connections, and were used much earlier than other non-separable connections (e.g., welded, soldered). Adhesives are widely used in the manufacture of vehicles, household appliances, aircraft, and medicine. One disadvantage of adhesive joints is their long bonding time (amounting, for example, to 72 h for polyurethane adhesives used in bus roof bonding), and another is their production of harmful waste. Tapes that are adhesive coated on both sides are increasingly being used to join parts during production. Such tapes have lower strength than

Abstract:

The role of sinusoid interface shape on the load bearing capacity of the adhesively bonded single lap joints has been investigated experimentally. The experimental results showed that the interface non-flatness can considerably influence the adhesive joint strength. The main parameters that can affect the load bearing of the non-flat joints are wave heights, wave lengths and also mechanical properties of adhesives and adherends. In this paper, the effect of wave length was evaluated as the key variable parameter. According to the experimental results for the best studied case, non-flat sinusoi

Abstract:

The demand for ever-lighter structures raises the interest in bonding as a joining method, especially for materials that are difficult to join with traditional welding and bolting techniques. Structural adhesives, however, are susceptible to defects, but can be toughened in several ways: by changing their chemical composition or by adding fillers, even of nanometric size. Nanomaterials have a high surface area and limited structural defects, which can enhance the mechanical properties of adhesives depending on their nature, quantity, size, and interfacial adhesion.

Abstract:

The use of adhesively bonded joints in place of traditional joining techniques such as bolted or rivet joints is becoming greatly popular in recent years. Interfacial stress in the adhesive is critical to the strength of adhesively bonded joints. It is necessary to predict the interfacial stresses accurately to ensure the safety of joints. In this work, an analytical model is explicitly presented to evaluate the stresses in a double lap joint. The equilibrium equations in the adhesive overlap region are derived on the basis of elasticity theory. The governing equations are presented in terms o

Bonded joints have been used in substitution of more traditional techniques as screws, rivets and mainly welding. However, the applications in which the work temperatures are relatively high remain as an obstacle to the use of more common polymeric adhesives.

This work deals with the adhesion of aluminium sandwich beams using geopolymeric adhesives. Metakaolin-based geopolymers were used as adhesives, activated with sodium and potassium silicates.

Abstract:

Conventional adhesively bonded joints, such as single-lap, curved-lap, wavy-lap, double-lap, stepped-lap, and scarf joints, are widely used for aerospace, automotive, and medical applications. These adhesively bonded joints exhibit different load transfer mechanisms and stress distributions within adhesive layers, which depend primarily on their geometries and mechanical properties of bonded materials. As such, joint geometry and material properties play a critical role in determining the capability of the joints to withstand high loads, resist fatigue, and absorb energy under impact loading.

Abstract:

The use of adhesive bonds has attracted considerable interest from the scientific community. Stepped-lap joints have the advantage of decreasing stress gradients along the bond length, although the outer steps still encounter stress levels above the steps in the inner zone of the joint. One possible way to reduce this stress gradient is to combine this type of joint with the use of two adhesives. This work consists of an experimental and numerical evaluation of stepped-lap dual-adhesive joints between aluminum adherends, for various overlap lengths ( LO), and comparison with stepped-lap single

The adhesive joints were made from a 316L steel sample and a sample made from polymethyl methacrylate. The adhesive joints were cured at three time intervals: 5 minutes, 10 minutes and 20 minutes.
