“…The impact response of the composite sample with BNNP added in the tests carried out at 23°C and 0°C changed compared to the neat samples, but there was no significant difference in the impact response of the BNNP added samples in the experiments performed at other temperature values. In studies 24,29 investigating the material's mechanical properties after BNNP was reinforced into the epoxy matrix, it was found that the nanoparticle reinforcement increased the toughness and rigidity of the sample. In parallel with these studies, it is seen in the graphs in Figure 5 that the maximum contact force values obtained from nanoparticle-reinforced samples, especially for room temperature and 0°C, are higher than the neat sample.…”

“…They observed that the addition of nanoparticles to the neat sample increased both burst pressure and tangential strength. Ustun et al, 29 in another study, examined the fatigue performance of nanoparticle-reinforced filament winding carbon epoxy composite pipes. They observed that adding nanoparticles to the sample increased the fatigue life of the material.…”

This study aims to investigate the low-velocity impact response of boron nitride nanoparticles (BNNPs) added carbon fiber reinforced pipes (CFRPs) at various temperature values. Carbon fiber/epoxy composite specimens with (±55°)3 winding angles were manufactured with the filament winding method. Low-velocity impact tests were performed with a 15 J energy level at five different temperatures between −196°C and 23°C ranges to understand the cryogenic environment effect on BNNP added carbon fiber reinforced tubes and neat carbon fiber reinforced tubes. The force-displacement and contact force-time graphs were attained in consequence of low-velocity impact tests. The damage areas, their size and characteristics were scrutinized both visually and with the aid of a Microscope. The test results showed that when ambiance temperatures decreased, the damage areas considerably increased both filled with BNNP and without BNNP filament wound carbon fiber reinforced tubes.

Seawater aging-dominated delamination failure is a critical design parameter for marine composites. Modification of matrix with nanosized reinforcements of fiber-reinforced polymer composites comes forward as an effective way to improve the delamination resistance of marine composites. In this study, we aimed to investigate experimentally the effect of halloysite nanotube nanoreinforcements on the fracture performance of artificial seawater aged basalt–epoxy composites. For this, we introduced various amounts of halloysite nanotubes into the epoxy and the halloysite nanotube–epoxy mixtures were used to impregnate to basalt fabrics via vacuum-assisted resin transfer molding, subsequently. Fracture performances of the halloysite nanotubes modified epoxy and basalt/epoxy composite laminated were evaluated separately. Single edge notched tensile tests were conducted on halloysite nanotube modified epoxy nanocomposites and the average stress intensity factor (KIC) was increased from 1.65 to 2.36 MPa.m1/2 (by 43%) with the incorporation of 2 wt % halloysite nanotubes. The interlaminar shear strength and Mode-I interlaminar fracture toughness (GIC) of basalt–epoxy hybrid composites were enhanced from 36.1 to 42.9 MPa and from 1.22 to 1.44 kJ/m2, respectively. Moreover, the hybrid composites exhibited improved seawater aging performance by almost 52% and 34% in interlaminar shear strength and GIC values compared to the neat basalt-epoxy composites after conditioning in seawater for six months, respectively. We proposed a model to represent fracture behavior of the seawater aged hybrid composite based on scanning electron microscopy and infrared spectroscopy analyses.

“…Moreover, cementitious materials also have the same durability as the monitored structure, which allows long-term applications. Many researchers have reported the exceptional mechanical enhancements of CNTs used as fillers in nanocomposites [16][17][18][19][20]. However, work reporting about the development of theoretical models capable of simulating the relationship between external mechanical strains and the effective electrical conductivity is still scant.…”
