“…Furthermore, few studies have reported on the relationship between accelerated aging and soil burial degradation of plant fiber-based lunch boxes, and the related literature focused primarily on using accelerated indoor aging to predict the long-term service life of plant-fiber composites outdoors, and predicting their actual service life by developing prediction models [ 20 , 21 ]. Plant fiber composites have a long natural aging time, and the models developed so far fall into two categories: the first is based on existing empirical formulas [ 22 ] (residual strength model, aging kinetics model, stress relaxation model, and so on), and the second is the development of an indoor accelerated aging environment spectrum using the environmental equivalent method [ 23 ]. Additionally, it is more typical to determine the parameters that serve as performance indicators to calculate the acceleration factor using the gray theory [ 24 ] and to create a correlation between accelerated aging and normal aging.…”

This study aimed to investigate the mechanical property decay that might occur during actual use and soil burial degradation of bamboo fiber lunch boxes. For this, the effects of three accelerated aging methods, namely damp–heat treatment, freeze–thaw cycle, and artificial weathering cycle, on the tensile strength, dynamic viscoelasticity, and chemical composition of bamboo fiber lunch boxes were compared, and a correlation of their mechanical property decay with soil burial degradation was established to obtain an acceleration factor (SAF) with aging time as a reference. The results showed that the mechanical properties of the bamboo fiber lunch box decreased to different degrees under the three accelerated methods, and the tensile strength decreased to less than 50% after 36 h of damp–heat treatment, 5 freeze–thaw cycles, and 11 artificial weathering cycles. However, after 10 days, the mechanical property of lunch box in soil degradation decreased by more than 50%. Infrared spectroscopy demonstrated rapid hemicellulose degradation during damp–heat treatment and freeze–thaw cycle, as well as a minor quantity of lignin, and a significant amount of lignin under artificial weathering cycle. With the freeze–thaw cycle and the artificial weathering cycle, the relative crystallinity dropped quickly, by 32.3% and 21.5%, respectively, but under damp–heat treatment, the crystallinity dropped barely, by 43.5%. The damage caused by the freeze–thaw cycle to the mechanical properties of bamboo fiber lunch boxes was greater than that by the damp–heat treatment and artificial weathering cycle. The fluctuation of SAF under freeze–thaw cycle was also more drastic. Compared to the artificial weathering cycle, the damp–heat treatment was more stable and reliable in predicting the decay law of soil burial degradation tensile strength of bamboo fiber lunch boxes.

“…In harsh environments, the mechanical properties of FRP composites deteriorate as the working temperature rises between 70-80 °C. The aging period, chemical treatment (such as exposure to the sea and distilled water), and working temperature have all been shown to influence the overall strength of FRP composites [38][39][40][41][42]. Recent research has shown that moisture influences matrix osmotic cracking due to the expansion of the gap between fiber and matrix, as well as the debonding of fiber and matrix.…”

The study investigates the impact of moisture environment treatment on the hoop tensile strength (HTS) of glass fiber-reinforced polymer (GFRP) composites, through hygrothermal aging. GFRP cylinders were fabricated with different parameters such as varied volume fraction, winding angle, and stacking sequences using a filament winding machine. The fabricated samples are subjected to hygrothermal aging using seawater and tap water with oil at 80°C for 1080 hours (45 days). The Hoop tensile strength tests were performed on unaged and aged samples. There was a reduction in HTS for aged samples which is attributed to heat, seawater contamination, and oil. The highest and lowest HTS values recorded are 402.9 MPa and 118.3 MPa for unaged and tap water with oil-aged samples respectively. HTS in aged samples is compared with unaged strength to identify the best-suitable combination for retaining HTS under various aging conditions.
