“…38,335 A number of papers published so far investigate the behavior of bolted and adhesively bonded connections. 330,[336][337][338][339] Several researchers also studied the influence of shear deformations and stress on the buckling behavior of pultruded structures. 310,[340][341][342][343][344] Table 5 presents primary studies (experimental, analytical, and finite element modeling (FEM)) investigating the influence of the fiber/matrix type and crosssectional characteristics on the shear behavior of pultruded elements due to different load cases as well as aiming to determine their shear moduli.…”

Currently, the application of pultruded profiles is increasing owing to their advantages, such as light weight, high strength, improved durability, corrosion resistance, ease of transportation, speed of assembly, and nonmagnetic/nonconductive characteristics. This review analyzes the main application fields of elements produced by pultrusion manufacturing processes: bridges and bridge decks, cooling towers, building elements and complete building systems, marine construction, transportation, and energy systems. Analysis of the scientific literature in relation to the mechanical behavior of pultruded elements is presented as well. Finally, this review outlines the future study possibilities, giving the researchers and practitioners the directions for deeper investigation of specific features and exploration of new ones concerning the mentioned aspects of pultruded fiber-reinforced polymer composites.

“…There are numerous studies in the literature aimed at investigating the stress distribution in the adhesive layer. However, one weakness of adhesive technology is the effects of exposure to moisture and high temperatures [11], [12]. In fact, exposure to humid environmental conditions leads to the presence of water, which promotes degradation phenomena on the adhesive [13].…”

The adhesive technique is observing a considerable increase in applications in various fields. Unlike traditional joining methods, this technology allows the stress peaks and the weight of the resulting structure to be reduced. Adhesive joints during their service life not only undergo mechanical but also thermal stresses. The thermal compatibility between the adhesive and the adherents used is a fundamental aspect to consider in the design phase. This paper reports on and analyses the results obtained from a linear Finite Element Method (FEM) simulation for a hybrid adhesive joint, as the thickness and characteristics of the adhesive layer vary. An analytical solution for adhesive free joints is presented according to both beam and plate theories. The analytical and numerical results, in case of no adhesive, are in good agreement with good approximation. The introduction of the adhesive layer allows to obtain higher displacement values than in the adhesive-free configuration. The increase in displacement and therefore in ductility confirms the effectiveness of the adhesive joint for real applications.

“…Since the overall performance depends on the response of the individual components of the joint, the reliability of dissimilar joints can be even more critical if the adherend materials have relative differences in their thermal expansion behavior [6]. This fact has motivated studies of environmental degradation and fatigue life of the adhesive and adherend materials [18][19][20][21][22][23][24]. The lifetime of the final product, the adhesive bonded joint, is affected not only on the individual behavior of its components, but also the behavior of the entire exposed joint, resulting from the manufacturing process and posterior degradation in service life [2,6].…”

Fiber-reinforced polymers (FRPs) combine characteristics of polymers and fibers to obtain a material with high mechanical strength and stiffness together with low specific mass and good corrosion resistance. The use of FRPs is growing as an alternative to metals in the automotive, aerospace and civil construction industries. Since adhesive bonded joints are an excellent way of joining materials due to the better load distribution, the use of FRPs for this purpose has been the objective of many studies about durability and structural safety. In service, environmental factors, including temperature, humidity, UV exposure and salt spray, can degrade materials, leading to unexpected failures. Since joints in service are subject to these multiple and uncontrolled adverse conditions, FRP adhesive bonded joint degradation has been studied by experiments that simulate these adverse environmental conditions. The combined analysis of the effect of environmental factors on the joint and the materials of each component allows predicting the system performance. In addition, optimal design parameters, such as the thickness of the adhesive, overlap length, materials and manufacturing processes, may be different according to the target application of the joint. Therefore, the achievement of optimal design parameters depends on the understanding of joint behavior in service. Based on analysis of the contribution of researchers in the specialized literature on adhesive joints and FRPs, this article reviews the main findings on degradation of adhesive joints and their components. Research topics for optimization of adhesive joint systems are also discussed.
