“…According to many authors described in their publications, such as Messler or Saboori [ 2 , 3 , 4 ], adhesive joints are also an alternative to other assembly joints in engineering applications because they have several advantages over conventional joining methods, while not altering the microstructure of the parts being bonded. The use of bonding technology allows for structures that are lighter in weight, yet have high strength, high fatigue life and reliability [ 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. Structural bonding is, in many cases, one of the methods of relatively fast integration of machine parts, installations, vehicles or aircraft [ 9 , 10 , 12 , 13 , 14 ].…”

One of the most important design factors in the constitution of adhesive joints is the correct choice of adhesive. Currently, there is a full range of options on the commercial market in this regard, but there is increasing research into modifying adhesives for specific engineering applications. The aim of this study was to analyze the effect of physical modification with fillers on the properties of the adhesive composition and the adhesive joints. The adhesives used in the study were a composition of Epidian 5 epoxy resin and PAC curing agent modified with 1% montmorillonite, 5% calcium carbonate and 20% activated carbon. The adhesive compositions in the cured state were subjected to strength tests and SEM and DSC analyses. Using these compositions, adhesive joints of EN AW 2024 T3 aluminum alloy sheets were also made. The tests carried out showed that, due to the use of different fillers, their effects on certain properties of the adhesive compositions are different types. It was shown that physical modification of the adhesive composition does not always result in positive effects. The study also attempted to determine the correlation between the properties of the adhesive compositions in the cured state and the strength of the adhesive joints.

“…The bonding technology also contributes to the design and the manufacture of lightweight yet strong structures with specific properties [ 6 ]. Because of this versatility, this technology is used in a wide range of industries, such as the aerospace, automotive and rail, and civil engineering industries as well as other industrial sectors where an effective high strength-to-weight ratio is important for the development of the innovative structures [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. As Messler describes in his publications [ 16 , 17 ], adhesive bonding technology creates the possibility of replacing other bonding methods without causing microstructural changes in the joined elements.…”

“…As indicated by the authors of Saboori et al [ 20 ] and Ziółkowski and Dyl [ 21 ], structural bonding may be a worthwhile alternative in repair and sealing processes, where regenerating parts in the repairs of machine structure elements, allows costs being able to be reduced. During vehicle construction, adhesive technology can be used to fix linings, brake pads, glass panes, joining elements of door skins, engine covers, and the boot [ 13 , 14 , 22 , 23 ]. Adhesive technology is also used in bus manufacturing due to the excellent damping properties of the adhesives.…”

“…Adhesive technology is also used in bus manufacturing due to the excellent damping properties of the adhesives. An important share is also recorded in the construction of self-supporting vehicle bodies [ 13 , 24 ]. These adhesives are also used to seal internal combustion engines, differentials, and transmissions and can also be used to reinforce thrust-bearing contact surfaces.…”

The Influence of Sandblasting Process Parameters of Aerospace Aluminium Alloy Sheets on Adhesive Joints Strength

2021

In this study, the influence of sandblasting process parameters as a surface preparation method on the strength of single-lap adhesive joints of EN AW 2024 T3 aerospace aluminium alloy sheets was determined. Eleven sets of sandblasting parameters were used, which were determined according to a determined experimental plan. The variable factors in the sandblasting process were pressure, nozzle distance, and workpiece displacement speed. The sand jet incidence angle was constant. Garnet 80 E+ was the abrasive material that was used. The joints were made using an epoxy adhesive composition of Epidian 5 epoxy resin and a PAC curing agent. The influence of the surface preparation method on the surface roughness and contact angle to determine the surface free energy was evaluated. The shear strength of the adhesive joints was also determined, which finally allowed the evaluation of the applied surface treatment variants. The obtained results were subjected to statistical analysis, which indicated that the highest shear strength of the adhesive joints was obtained for samples whose surfaces were treated by sandblasting at parameter configurations in which the pressure was 5–6 × 105 Pa; the distance between the nozzle and the sandblasted surface should not be greater than 97 mm, and the speed at which the workpiece moves in relation to the nozzle should not be greater than 75 mm/min.

“…In addition, they have gained considerable ground in high-performance applications, such as the aerospace [ 8 , 15 ], marine [ 16 ], military [ 17 ], and automobile industries [ 18 ]. Especially, the last decade has seen a very significant increase in the use of carbon fibre reinforced polymers (CFRPs) [ 19 ], as shown in Figure 1 .…”

Life cycle assessment is a methodology to assess environmental impacts associated with a product or system/process by accounting resource requirements and emissions over its life cycle. The life cycle consists of four stages: material production, manufacturing, use, and end-of-life. This study highlights the need to conduct life cycle assessment (LCA) early in the new product development process, as a means to assess and evaluate the environmental impacts of (nano)enhanced carbon fibre-reinforced polymer (CFRP) prototypes over their entire life cycle. These prototypes, namely SleekFast sailing boat and handbrake lever, were manufactured by functionalized carbon fibre fabric and modified epoxy resin with multi-walled carbon nanotubes (MWCNTs). The environmental impacts of both have been assessed via LCA with a functional unit of ‘1 product piece’. Climate change has been selected as the key impact indicator for hotspot identification (kg CO2 eq). Significant focus has been given to the end-of-life phase by assessing different recycling scenarios. In addition, the respective life cycle inventories (LCIs) are provided, enabling the identification of resource hot spots and quantifying the environmental benefits of end-of-life options.
