“…One possible way to achieve good results focuses on developing advanced materials considering successful cases reported with metal alloys and composite materials based on ceramics reinforced with carbon nanotubes, graphene, or carbon fibers [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ]. Some properties of interest include fatigue resistance, durability, tensile strength, and corrosion resistance in submarine and salt-rich environments where the replacement of metals is desirable [ 13 , 14 , 15 ]; low energy power consumption during the manufacturing process; and relatively fast processing and self-healing capability on fracture [ 16 ]. Among several alternatives, carbon-fiber-reinforced polymer composites (CFRPCs) have emerged as an excellent choice, meeting most of these characteristics because of their manufacturability and superior properties [ 1 , 2 , 3 , 11 , 12 ].…”

In this study, the kinetic parameters belonging to the cross-linking process of a modified epoxy resin, Aerotuf 275-34™, were investigated. Resin curing kinetics are crucial to understanding the structure–property–processing relationship for manufacturing high-performance carbon-fiber-reinforced polymer composites (CFRPCs). The parameters were obtained using differential scanning calorimetry (DSC) measurements and the Flynn–Wall–Ozawa, Kissinger, Borchardt–Daniels, and Friedman approaches. The DSC thermograms show two exothermic peaks that were deconvoluted as two separate reactions that follow autocatalytic models. Furthermore, the mechanical properties of produced carbon fiber/Aerotuf 275-34™ laminates using thermosetting polymers such as epoxies, phenolics, and cyanate esters were evaluated as a function of the conversion degree, and a close correlation was found between the degree of curing and the ultimate tensile strength (UTS). We found that when the composite material is cured at 160 °C for 15 min, it reaches a conversion degree of 0.97 and a UTS value that accounts for 95% of the maximum value obtained at 200 °C (180 MPa). Thus, the application of such processing conditions could be enough to achieve good mechanical properties of the composite laminates. These results suggest the possibility for the development of strategies towards manufacturing high-performance materials based on the modified epoxy resin (Aerotuf 275-34™) through the curing process.

“…To enlarge the scope of FRP's application, since its brittle and anisotropic properties, which are its parts of primary disadvantages to traditional metal materials, it is necessity of the improvement on advanced joint technology. Overall, there are two main joint methods, the adhesive bonding technique, [20,21] lower weight and fewer components, and the bolt joint technique, [22][23][24] higher reliability, commonly used technologies for composite constructions. Mechanical bolted shear connections are the primary connection type of pultruded FRP material because they are familiar and easy to use.…”

“…Because of its low weight and fewer components, the adhesive bonding technique has become one of the most critical technologies for composite structures. [11][12][13] Though the composite structures have a variety of advantages such as light weight, high corrosion, and fatigue resistance et al, they are sensitive to low-velocity impact loading, which could cause various types of damage and threaten their mechanical performance further. After the LVI event, the damages on the composite structures usually consist of fiber breakage, matrix crack, and interface delamination.…”

In this study, an experimental methodology, consisting of low-velocity impact (LVI) and quasi-static compressive test, is conducted to investigate the performance and failure mechanism of GFRP T-joints, fabricated by vacuum-assisted resin infusion process (VARI), when subjected to out-of-plane LVI loading at the corner. Further, the effect of LVI loading on the reduction of strength is analyzed by the tensile test after LVI. In order to improve the strength of the GFRP T-joints, one layer of stainless-steel wire net (SSWN) is inserted into the corner of the T-joints structure. The experimental results indicate that the addition of SSWN decreases the damaged area of delamination in the web, meanwhile, connecting the nearby GFRP layers to avoid the structure failure suddenly, which improves its performance of tensile test after LVI.
