“…After rinsing the eggshells in water to remove the membrane, they were placed on a circular stainless steel tray and dried in the sun for 6 h after being cleaned. Manual crushing of the dry eggshells was accomplished with the use of hand compression, and then fine pulverisation was accomplished in a planetary ball mill for three hours before being removed from the mill [ 19 , 20 , 21 , 22 ].…”

In today’s scenario, composite materials play a vital role in automobile, aerospace, and defence sectors because of their higher strength, light weight and other mechanical properties. Aluminium alloy Al6082 is a medium strength alloy with good corrosion resistance properties; hence, it is used for high-stress applications, bridges, cranes, etc. The present work focuses on comparing the mechanical properties of Al6082 and Al6082 with the addition of silicon nitride, magnesium, and bio waste of eggshells. Samples of Al6082 reinforced with 2% of silicon nitride (Si3N4), 5% of eggshell, and 1% magnesium reinforcements were prepared using the crucible casting process. Mechanical properties were evaluated through hardness test, tensile test and compressive tests, which varied with the additives of reinforcement materials. The results showed that the reinforced materials could increase mechanical properties. Further, it will be analysed by the machining parameters involved through the CNC turning process. Analysis of variance from optimisation technique shows a noteworthy increment of material removal rate (MRR) and significant decrement in surface roughness (Ra) and machining time compared to standard aluminium. Additionally, the analysis of mechanical testing has been predicted with the outcomes of stresses and displacements using the ANSYS platform.

“…The mechanical behavior of the closed-cell aluminum-alloy foams subjected to various quasi-static loads in thermal condition was presented by Linul et al [16] as well. In another study, Prakash et al [17] confirmed that producing the Al/CNT nanocomposites with the stir casting method can increase the homogeneity of nano-additive dispersion throughout the metal matrix, and the mechanical characteristics can thereby be improved. In another study, Lee et al [18] employed the stir-casting technique to prepare the Al nanocomposite specimens and found that by increasing the B 4 C volume fraction up to 20%, the tensile resistance of B 4 C/Al-6061 was improved compared to the base Al alloy.…”

Lightweight aluminum alloy components are often used to manufacture a variety of engineering components in many industries. In recent years, researchers have studied the effect of improving the mechanical properties of metal alloys by incorporating nano-carbon into its structure. In this study, the effect of the addition of 0.2, 0.5, and 1 wt% of multi-walled carbon nanotubes (MWCNTs) on the stress–strain behavior and creep phenomenon of an A356 aluminum alloy were studied. The effect of nickel coating on 0.2 wt% MWCNTs was also investigated. Samples were prepared using the stir-casting method. The results revealed that the grain size became finer when MWCNT nano-particulates were introduced. Although the MWCNTs were distributed homogeneously in the A356 matrix, as confirmed by FESEM analysis, there were some agglomerations observed in a specific area with dimensions smaller than 100 nm. Nevertheless, the addition of MWCNTs was found to be beneficial in enhancing the hardness of alloys containing 0.2 wt%, 0.2 wt% nickel-coated, 0.5 wt%, and 1 wt% MWCNTs by 9%, 24%, 32%, and 15%, respectively, as compared with the unreinforced A345 matrix. It was also found that the 0.5 wt% MWCNT-A356 matrix exhibited an improvement in the creep lifetime by more than two orders of magnitude.

“…The widespread use of electronic devices and instruments in various scientific, military and commercial applications, and the spectacular growth of modern communications have promoted the development of new materials appropriate for the mitigation of electromagnetic interference (EMI), as a topic of great interest [1]. Among the materials with the desired characteristics are metals in solid or powder form, metal-fiber filled plastics, polyacrylonitrile nickel-coated reinforced polymers, aluminum structures, coatings, nickel and copper metalized fabrics, as well as nanoreinforced polymer composites [2], [3], [4]. In order to determine the electromagnetic properties of the new materials and their possible…”

Characterization of the Electromagnetic Shielding Effectiveness of Biochar-Based Materials

Biochar and biochar-based composites are multi-functional materials with a wide range of environmental and other applications. A new and emerging application is in the field of modern communication systems as materials with significant electromagnetic shielding effectiveness. In this study, biochar was prepared from olive tree prunings which was subsequently used at various dosages to prepare composite samples with carbon black and polytetrafluoroethylene as binder. The electromagnetic shielding effectiveness of the samples were measured in the frequency range of 1-3 GHz, using a simple, user-friendly and reliable experimental set-up. The results showed that raw, unmodified biochar had a low shielding effectiveness in the range of 1.5-4 dB however, it slightly increased as the thickness of the sample increased from 0.1 to 0.5 mm. Modifying biochar with the 20 %w/w acetylene black largely increased its shielding effectiveness, reaching the value of 39 dB in the same frequency range. Our approach demonstrated that raw biochar can be used as a substrate to develop composite materials with significant shielding effectiveness and assess their performance with a quick and simple laboratory method.
