“…The cobalt accelerator and MEKP catalyst are also thoroughly mixed into the nanoclay-polyester mixture before being poured into the molds. The specimen molds are made according to ASTM standards D638-14 14,17 (dumbbell-like shape) and D790-10 14, 18 (a rectangular shape with 140 mm × 15 mm × 3 mm dimensions). The prepared specimens are shown in the Figure 2.…”

“…The prepared specimens are kept in the tap water at room temperature. The specimens are weighed weekly during the water soaking tests (ASTM D570-98 standard 14,19 ) using a digital weighing apparatus to find the difference in weight and water uptake percentage. The specimens are kept in water till the saturation point and followed with oven re-drying at 110°C for 24 hours.…”

This research aims to investigate the influence of water soaking and re-drying on the mechanical and wear properties of nanoclay-polyester nanocomposites (NPNCs). The nanoclay addition significantly enhances the mechanical properties of NPNCs in as-made, water-soaked and re-dried conditions. Also, the addition of nanoclay decreased the percentage of reduction in mechanical properties under water-soaking condition. Re-drying recovers more than 90% in values of mechanical properties compared to original values. In contrast, the addition of nanoclay reduces the mass loss (wear test) of specimens in all three conditions. Re-dried specimens have lesser mass loss than water-soaked specimens and greater mass loss than as-made specimens. SEM images illustrate that the absorbed water can alter the fracture and worn-out surface by swelling and plasticization. Also, SEM images reveal that re-drying can reverse the effect of swelling and plasticization of the specimens.

In this study, solid styrene‐butadiene rubber (SBR) compound nanocomposites containing hybrid nanoclay–graphite nanofillers with different weight fractions were fabricated through a two‐roll mill process, and surface response methodology (SRM) using Minitab software was employed for designing experiments and developing good relationships between independent factors and responses. The impact of nanoclay, graphite, and their hybrids on the mechanical, aging, and thermal properties of filled SBR was studied. Compared with neat SBR, the SBR containing 10 phr nanoclay and 15 phr graphite (SBR/10/15) showed the highest tensile strength and tensile modulus with 55 and 47% rise, respectively. Also, A maximum increase in hardness was observed for SBR/5/30 by 42%, and it was revealed that nanofillers reduced the elongation at break. Additionally, despite reducing the mechanical properties of neat SBR, hybrid nanocomposites maintained their properties during aging so that the SBR/10/15 presented maximum aging resistance. The SBR/10/15 presented maximum aging resistance as it significantly retained its mechanical properties during the test. Moreover, thermal stability was investigated using thermogravimetric analysis (TGA). The results demonstrated that the hybrid nanofillers improved the thermal stability of SBR.

In this research, modified castor oil (MCO)‐based biocomposite has been synthesized and its structure is strengthened with waste polyethylene (PE) reinforcement. Both the petrochemical raw material used is reduced by 12 wt% and a new environmentally friendly biocomposite is produced using waste PE. Considering some thermophysical properties of the obtained biocomposite, experimental working conditions, and composition ratios have been optimized with response surface methodology (RSM). The chemical bond structure of the biocomposite has been investigated by Fourier transform infrared spectrophotometer, thermal decomposition behavior by thermogravimetric analysis, and surface morphology by scanning electron microscopy. According to the results obtained, the density and hardness of the biocomposite synthesized by the addition of MCO to unsaturated polyester (UP) decreases, and its thermal conductivity and thermal stability increase. The thermal decomposition kinetics of the biocomposite is also modeled with the newly improved hyperbolic function equation. The relationship between conversion rate and the temperature has been determined by the new model with a high correlation coefficient (R2 = 0.9985) and low‐error functions (SST = 0.0096, RMSE = 0.0285, χ2 = 0.0037). Effective and efficient use of MCO, UP, methyl ethyl ketone peroxide, and cobalt octoate in the production process has provided an economical and steady the biocomposite. Evaluation of experimental data with both RSM and artificial neural networks raises the reliability of the model results.
