“…Polymer composites are intensively studied as replacements in common applications in many industrial fields due to their wide range of properties, such as aerospace, automotive, construction, marine, transportation, electronics, agriculture, furniture, packaging, and sports. [1][2][3][4][5][6][7][8] Polymer composite materials are the combination of two or more materials with different properties in a product that has superior characteristics over the individual component. 9,10 One component is called a matrix and embeds the other component, which is called the reinforcement.…”

The hemp-reinforced polypropylene composite was produced by the twin-screw extrusion in the presence of polypropylene-graft-maleic anhydride (PP-g-MA) and silane as coupling agents and subsequence by the compression molding. The hemp fiber was obtained by sodium hydroxide treatment prior to the twin-screw extruder. The PP/Hemp composite was analyzed using a universal testing machine, scanning electron microscope, differential scanning calorimetry, X-ray diffraction, and Fourier transform infrared spectroscopy. The mechanical properties of the PP/MA/Hemp demonstrated a better result than that of PP/Si/Hemp in most hemp contents. The SEM images of the PP/MA/Hemp exhibited excellent interfacial bonding in PP/MA/Hemp30 without fiber pullouts. However, the fiber breakage and some fiber pullout with gaps around the fiber of PP/Si/Hemp indicate the poor bonding of the PP matrix. The functional group of the PP/Hemp composite showed the –OH cellulose result peak of the reaction between hemp fibers and polypropylene.

In this article, the numerical and experimental results for buckling analysis of a nanocomposite beams reinforced by nanorods are studied and compared. The Chebyshev–Ritz method is used to calculate the buckling numerically and compare it with the buckling test. Epoxy resin, glass's fiber, and nanorods are used to make composites. These nanorods are made using recycled materials. Also, bending and tensile tests are used to obtain the properties of these composites. In addition, the effect of various parameters such as Young's modulus, temperature change, Poisson's ratio, and boundary conditions, the strain gradient parameter, and different shape function is investigated. The addition of nanorods increases the strength and stiffness of composites and increases the critical buckling load. Actually, the made nanorods are used as a reinforcement in matrix, thus in the made nanocomposites, fracture and buckling tests are done and the results indicate that the inclusion of nanorods (0.32%) increases the critical buckling load by 16.4%. A facile hydrothermal method to synthesis the nano rodes has a less cost with the other methods, thus by adding a small percentage of it to the composite, the stiffness of the structure increases. According to the results and the significant increase in Young's modulus and critical buckling load and the cost‐effectiveness of carbon nanorods (CNRs) made from recycled materials, these environmentally friendly reinforcements can be used in various industries such as machine body construction, automobile manufacturing, shipbuilding and construction of type's turbines.Highlights Using potato peels and hydrothermal methods, CNRs produced. These CNRs are useful, and production is cheap and no harm environmental. Buckling sample include of glass fiber, without and with CNRs and epoxy resin. Third order shear deformation beam theory and Chebyshev–Ritz are used Theoretical and experimental buckling critical load are compared.

In this study, the challenges of using nanoparticles such as graphene oxide (GO) and modified graphene oxide (MGO) in the production of thick parts were investigated. In addition, using various kinetic models, the trend of temperature increases in pure unsaturated polyester resin (UPR), and UPR containing GO and MGO were investigated. The heat transfer equations were solved using programming code in MATLAB software. In the following, the role of the variation in density, convection heat transfer coefficient, and thermal conductivity coefficient on the prediction of temperature at different points of the parts is evaluated. The findings indicated that the choice of the kinetic model can play an effective role in predicting the temperature in the parts. An increased temperature causes a decrease in the structural regularity of the resin network and intensifies phonon scattering to decrease, and will eventually cause a decrease in the thermal conductivity coefficient.Highlights The mathematical modeling was developed on the curing of unsaturated polyester nanocomposite. The cure kinetic models and thermal properties had important roles in the model accuracy. The best prediction of temperature changes was provided by Vyazovkin's model. The results of developed model satisfactorily matched the experimental data.
