“…Further research into the improvements of AMCs has led to the consideration of certain waste materials in the fabrication process. Citing the need for environmental sustainability and cost savings, studies in [4,5] have considered the use of waste materials for the fabrication of AMCs. Such materials that have been utilized include fly ash [6], red mud [7], rice husk ash [8], and coconut shell ash [9].…”

In this paper, the effect of the carbonization temperature on the mechanical properties, density, wear and corrosion resistance of AA 6063 reinforced with eggshells was investigated. The selected fabrication route for this investigation was stir casting while the weight fraction of the eggshells was kept constant at 5 wt.%. The carbonization temperature was varied at 900, 1000, 1100, and 1200 °C. The microstructure revealed that the eggshells were fairly uniformly dispersed on the individual grains and along the grain boundaries of the base metal. It was also shown that the presence of agglomeration increased with increasing carbonization temperature. The densities of the eggshell-reinforced AMCs were lower than that of the base metal. The analysis of the microhardness showed an improvement of 40.79, 22.93, 25.70, and 29.43% for the 900, 1000, 1100, and 1200 °C carbonized eggshell samples, respectively. The compressive strength studies showed that the addition of carbonized eggshells improved the compressive strength of the composites compared to the base metal. The tribology studies showed that the wear resistance improved for the 900 and 1200 °C samples, while the electrochemical studies revealed that the corrosion resistance improved for the 900 and 1000 °C samples only.

Natural fiber composites offer a range of advantages, from biodegradability after the component’s lifespan little to no output of greenhouse gases and reduced pollution. These properties have made natural fiber composites popular in military, automotive, aerospace, and residential spaces. Bamboo Stem Ash Powder (BSAP) is one example of a commonly found natural fiber composite. This research looks into its effect on the physical and mechanical parameters when added to pure aluminum. The 0, 2.5, 5, 7.5, and 10 weight percent of BSAP were added in addition to the secondary reinforcements in the matrix. Parameters such as density, porosity, hardness, compressive strength, X-Ray Diffraction analysis results of BSAP/composite mixture, as well as Thermal Gravimetric Analysis (TGA) findings for the BSAP itself were all studied. The highest values of hardness 239.66 HV and compressive strength 308.32 MPa have been observed with 7.5 weight percent BSAP addition. It can be confirmed that these natural fiber composites can improve standard materials’ behavior when used correctly and can be potential candidates for many engineering applications.

“…These composites are already poised to replace conventional materials for the purpose already stated. Among the applicable base metals for MMC fabrication, aluminium has received numerous attention because of its lightweight, corrosion resistance, and adequate strength-to-weight ratio [1]. Research into the fabrication of aluminium matrix composites (AMCs) has yielded noteworthy improvements in the properties under investigation such as research done by Ikumapayi et al [2] to study the effects of coconut shell ash, cow bone ash and palm kernel ash on corrosion resistance of AA 7075.…”

This work investigated the effect of carbonized eggshell and fly ash on the microstructure, mechanical properties and machinability of AA 6082. The fabrication method selected for this study was stir casting. For the hybrid metal matrix composite, the weight fraction was 2.5wt% carbonized eggshell and 2.5wt% fly ash. The microstructural examination of the cast composite showed an even dispersal of the reinforcing phases in the aluminium matrix. Density analysis saw a 10.66% reduction of the cast composite in comparison to the aluminium alloy. Improvements of 12.32%, 21.91%, and 8.30% were recorded for the microhardness, tensile strength and compressive strength respectively. The wear studies of the cast samples revealed coefficients of friction (CoF) of 0.499 and 0.290 for the base metal and the AMC respectively. For the machinability studies, the surface roughness and flank tool wear were the responses under consideration. The design of experiments was conducted using the Taguchi method. The input parameters for this investigation was the cutting speeds (100 mm/min, 200 mm/min, 300 mm/min), feeds (0.1 mm/rev, 0.2 mm/rev, 0.3 mm/rev) and depths of cut (0.5 mm, 1.0 mm, 1.5 mm). For the multi-response optimization, Taguchi based grey relational analysis was used. The analysis of variance (ANOVA) of the grey relational grade (GRG) revealed that the feed was the most influential factor on the surface roughness and tool wear. The initial optimization showed the optimal cutting speed, feed and depth of cut as 200 mm/min, 0.2 mm/rev and 1.5 mm respectively. The confirmatory experiments revealed that the optimal combination of factors was 200mm/min, 0.2 mm/rev and 0.5 mm for the cutting speed, feed and depth of cut respectively.
