“…Their results indicated that the composites containing of encapsulated halloysite nanotubes were able to heal the scratches completely and recover the structural functions in the presence of sunlight. Xu et al 25 improved durability of glass fiber reinforced polymer composites by incorporation of nano ZnO and organo-montmorillonite subjected to UV radiation and hygrothermal aging. They could increase the flexural strength and interlaminar shear strength by 26.5% and 27.2%, respectively in hygrothermal condition.…”

Today, advanced materials like fibrous composites are widely used in the industry due to their favorable strength-to-weight ratio, corrosion resistance and many other suitable properties. Buckling phenomenon may occur in a thin composite structure subjected to high compressive loads. Moreover, the buckling strength of polymer based composites such as glass/epoxy decreases due to sunlight radiation. In this research, the effect of adding zinc oxide (ZnO) nanoparticles as a reinforcement to the matrix material of glass/epoxy composite on the critical buckling load of the beam specimens is investigated experimentally. In addition, samples are exposed to simulated sunlight irradiation and the effect of adding nanoparticles is investigated. Rectangular composite beams are made and reinforced with 1 wt. % of ZnO nanoparticles. Beams are clamped under tensile testing machine for buckling test. Compressive load is applied to the beams in the longitudinal direction and force-displacement graphs are plotted. Results indicate that the addition of ZnO nanoparticles into the epoxy resin increases the critical buckling load of these beams. As the results show, the critical buckling load of ZnO reinforced glass/epoxy specimens increases by %39.4 with respect to that of glass/epoxy samples. Moreover, to investigate the effect of adding nanoparticles after sunlight irradiation, some samples were placed in the accelerated weathering system for 24 h. Buckling test results represent a remarkable increase in the amount of critical buckling load for ZnO/glass/epoxy specimens even after the irradiation. SEM images of the break section of ZnO reinforced glass/epoxy specimens illustrate homogeneous dispersion of ZnO nanoparticles in the epoxy resin.

“…Incorporating nanoclay helped in a significant drop in water uptake behavior in nanocomposites compared to neat epoxy composites. Xu et al [30] worked on the durability enhancement of polymer/glass-fiber composite with the addition of ZnO/OMMT nanofillers. The nanocomposites were subjected to hygrothermal aging (30 C, 50 C, and 60 C) and UV radiations for 90 days.…”

In the present work, the accelerated aging of glass/epoxy composite bolted joints was carried out for performance evaluation. The woven glass fiber was used as reinforcement and an optimum wt% of nanoclay as filler was used to counter the accelerated aging attack. The bolted joint specimen and its testing fixture were designed as per ASTM D5961 considering width to hole diameter ratio (W/D) and edge to hole diameter ratio (E/D) as 6 and 5, respectively. The specimens were tested with and without the metal inserts. The specimens were given a cyclic exposure of 8 h of ultraviolet radiation (at 60°C) followed by 4 h of condensation (at 50°C), for a maximum of 500 h. The bolt torque of 0, 2, and 4 Nm were used for the failure analysis of the joint. The metal insert and nanoclay particles proved to be positive contributors for the performance of bolted joints under accelerated aging conditions.
