“…Berhanuddin et al 34 added 0.5 wt.% of graphene nanoparticle to the epoxy to improve its mechanical properties. Dandapani et al 35 added 0.5 wt.% graphene to epoxy to improve its thermal stability. Based on the available evidences, the addition of graphene nanomaterials and carbon nanotubes in percentages lower than 0.1 wt.% to the composite matrix does not have a considerable effect on the mechanical and thermal behavior of the composite.…”

Nanoparticles are considered as feasible strengthening agent which strengthen different types of polymeric materials with minor reduction in the density of composites. In this study, 0.1 and 0.5 wt. % Graphene Nano Platelets (GNPs) are added to the matrix of basalt fiber reinforced epoxy composites (BECs) and the effects of such addition on low velocity impact behavior are investigated. In this regard, the epoxy matrix is reinforced in macro scale by basalt fibers weaved together in 2/2 Twill pattern. Vacuum Assisted Resin Infusion Molding (VARIM) method is used to fabricate the pure and multi-scale BECs. The profile energy method is also used to evaluate the penetration and perforation threshold of fabricated pure and multi-scale BEC specimens. The force versus time and deflection, energy and deflection versus time curves are plotted and the key parameters of low velocity impact test including maximum force, energy and deflection are compared. According to the results, introducing of GNP nanoparticles in the matrix of BECs improves the low velocity impact behavior of these composites by increasing the contact force and decreasing the absorbed energy in rebounding state. Finally, based on the experiments, the 0.5 wt.% BEC has the best impact performance by applying 15.08 kN impact force against the applied forces of 13.78 kN and 11.208 kN for 0.1 wt.% and pure BECs.

“…According to the results, 0.5 wt% of modification graphene gave the increment of 25% and 26.29% for Young's modulus and maximum stress, respectively. Dandapani et al 57 showed that the addition of 0.5% of graphene nanoparticle to the epoxy increased its thermal stability considerably. Based on the available evidences, the addition of graphene nanomaterials and carbon nanotubes in percentages below 0.1% to the composite matrix does not have a considerable effect on the mechanical and thermal behavior of the composite.…”

In this study, effects of addition of carbon nanotubes (CNTs) and graphene platelets (GPLs) on characteristics of carbon/basalt fiber reinforced intra-ply hybrid composites were investigated. The composites were fabricated using vacuum assisted resin infusion molding (VARIM) method in two types including bare and 0.1, 0.5 wt.% of GPL and CNT nanoparticles filled hybrid composites. Fabricated normal and multiscale composites were cut by water jet and mechanical properties of specimens were examined by tensile, flexural, SBS experiments. Therefore, the modulus of elasticity, flexural modulus, tensile and flexural strength and ILSS of bare and multiscale composites were compared. Thermomechanical properties of fabricated composites were evaluated by dynamic mechanic analyze (DMA), thermogravimetric analyze (TGA) and thermal conductivity (TC) tests and storage modulus, loss modulus, damping ratio, glass transition temperature, weight loss and derivative weight loss were compared in fabricated normal and multiscale composites. Similarly, modal properties of fabricated composites such as natural frequency and damping factor were obtained by vibrational tests and compared in fabricated composites. According to the results, the addition of carbon-based nanoparticles improved the characteristics of carbon/basalt fiber intra-ply hybrid composites.The response of composites was directly proportional to the addition ratio of the carbon-based nanoparticles.

The densely packed electronic components in electronic devices emit electromagnetic (EM) radiations, and the interaction of the emitted EM radiations with external EM signals of neighboring components leads to device malfunctions and also creates health issues in human beings. Particularly, in aircraft, EM interference is a serious threat that leads to disastrous outcomes. The shielding of electronic components is an ideal way to reduce the pollution of electromagnetic interference (EMI). The mechanism of EMI shielding efficiency is discussed elaborately in this article. The factors associated with the EMI shielding of materials are discussed in detail. The EMI shielding by reflection and absorption are two possible routes to improve the shielding performance of the shielding materials. This article also highlights the EMI shielding mechanisms by reflection and absorption. However, the risk of secondary EM pollution is associated with the reflection of EM waves. This review also outlines the methods to improve the absorption‐based shielding performance of the materials. The significance of the microstructure of the shielding materials in enhancing the absorption‐dominant shielding efficiency is also presented with a detailed analysis. This helps to fabricate the absorption‐dominant EMI shielding materials with suitable microstructures. The EM loss is associated with the magnetic, dielectric, and conduction losses according to EM theory.Highlights This article highlights the recent progress in epoxy‐based EMI shielding materials. EMI shielding mechanisms by reflection and absorption are discussed elaborately. Reviewed the methods to improve the absorption‐based shielding performance in detail. Materials with EMI shielding efficiency greater than 30 dB are highly preferable.
