Mechanical properties and microstructural analysis of Al–Si–Mg/carbonized maize stalk waste particulate composites

Archachatina marginata bio-shells as reinforcement material in metal matrix composites

“…The limited availability and high cost of commonly used synthetic reinforcement material in metal matrix composites (MMCs) had hindered the industrial production of MMCs on a large scale for instance, in the automotive industry [1][2][3][4][5][6]. Thus, researchers are now focusing on the use of industrial and agro allied waste products as an alternative source of reinforcement materials in the MMCs production at low costs that are future assured as a way out of the current limitation.…”

Aluminium matrix hybrid composites: a review of reinforcement philosophies; mechanical, corrosion and tribological characteristics

“…Moreover, most developing countries are not as industrialized as developed countries so the use of industrial waste (fly ash) is quite scarce as these wastes are limited. The agro wastes studied in the past for the purpose of using them as reinforcement in AMCs include: bamboo leaf ash (BLA), rice husk ash (RHA), bagasse ash (BA), palm kernel shell ash (PKSA), maize stalk ash (MSA), corn cob ash (CCA), bean shell waste ash (BSWA) just to mention a few [12,14,15,18,19,49]. Prior to the development of hybrid AMCs with agro waste ash serving as complementing reinforcement, single reinforced AMCs have been developed.…”

“…Likewise, the merits of using discontinuous ceramic particulates or whiskers over continuous ceramic fibres for producing aluminium matrix composites (AMCs) are available in literatures [4,5,11]. However, high cost and limited supply of conventional ceramic reinforcing materials especially in developing countries has remain a major problem associated with the development of discontinuously reinforced aluminium matrix composites (DRAMCs) [12]. Other challenges facing DRAMCs that are reported to be of interest to researchers are inferior ductility, low fracture toughness and inability to predict the corrosion behaviour of AMCs [5,13].…”

Mechanical and tribological behaviours of aluminium hybrid composites reinforced by CDA-B4C

“…The benefits of adding agro waste are low cost, ease of access, low density and reduced pollution. Agro waste like ground nut shell ash (GSA) , bamboo leaf ash(BLA), rice husk ash (RHA), bagasse ash, palm kernel shell ash, maize stalk ash, corn cob ash (CCA), bean shell waste ash etc are researched and promising results have been reported [32][33][34][35][36][37][38][39][40][41][42][43][44]. Fatile OB et al have reported by adding the corn cob with SiC has no significant rise of porosity but while increasing the percentage of corn cob reduces the mechanical properties gradually.…”

“…Singh et al studied the effect of percentage reinforcements of RHA and fly ash on impact strength and reported that increase in RHA and mixture of fly ash has increased the absorption capacity of the composite up to 15% [42]. Oghenevweta JE et al investigated on maize stalk and reported that the mechanical properties like tensile strength and hardness have increased and impact has reduced slightly when compared with the base aluminium [43]. From the literature review it is clear that the agro waste serve as promising reinforcement in enhancing the properties of composite materials.…”
