The demand for magnesium (Mg) alloys is increasing in many industries, such as automotive and aerospace, thanks to their low density and high specific strength. However, the poor tribological performance of Mg alloys is one of the most important disadvantages that limit their widespread use. Researchers have developed different approaches to improve the wear performance of Mg alloys, such as alloying, coatings, surface modifications and composite production. Wear performance of systems with sliding parts are crucial for a lifetime and energy efficiency. The development of Mg matrix composites can significantly reduce energy loss by reducing damage from friction and wear. For this reason, it is crucial to understand the wear behaviour of recent Mg matrix composites. The effect of different parameters such as load, sliding speed, reinforcement content, reinforcement type and temperature on the wear performance of Mg matrix composites were investigated.

With an inherent lowest density and distinct solubility with enhanced mechanical behavior reason, the magnesium alloy composite is extensively used in the auto and aero sectors. The processing of magnesium alloy found micro‐cracks and voids between the oxidation spot, which fails properties. Through the sulfur hexafluoride (SF6) atmosphere, the AZ91D alloy hybrid nanocomposites are synthesized with 10 wt% alumina (Al2O3) and 0, 3, 6, and 9 wt% of silicon carbide (SiC) nanoparticles via a liquid state process with 400 rpm stir speed followed by vacuum die casting. The effect of SiC actions on physical behavior, microstructural formation, and mechanical properties of AZ91D/10 wt%Al2O3, AZ91D/10 wt%Al2O3/3 wt% SiC, AZ91D/10 wt% Al2O3/6 wt% SiC, and AZ91D/10 wt% Al2O3/9 wt% SiC composites are studied and its results compared with cast AZ91D alloy. Due to the actions of SiC in AZ91D/10 wt%Al2O3, the composite density conforms to the rule of mixture, and the void and micro‐cracks are limited (less than 1%) by the impact of the casting process, as evidenced in the microstructural illustration. An effect of 10 wt% Al2O3 and 9 wt% SiC contents in AZ91D facilitates maximum tensile strength of 181 MPa, improved elongation percentage of 2.2%, optimum hardness of 85HV, and superior impact toughness of 21.8 J/mm2, which is higher than the all other compositions.

“…The PMCs have attracted considerable attention as engineering materials due to their low cost, lightness and corrosion resistance properties. However, PMCs suffer failure under low stress thus, limiting their applications in machine components requiring high strength, thermal resistance and low wear rate [1,2]. To overcome these limitations and enhance their suitability, synthetic fibres can be incorporated into the composite.…”

The use of Synthetic Fibres (SF) as reinforcement for development of Epoxy-based Composites (EC) is well reported. Aside the fact that SF reinforced EC suffer failure under low stress, SF are harmful and sparse, thus limiting local synthesis of the composite for fabrication of structural components. The foregoing necessitates the search for sustainable agro-based alternatives such as Banana Pseudo Stem Fibre (BPSF). Therefore, attempt was made to study the use of BPSF as partial or wholly alternative to SF in EC. The synergistic influence of BPSF and SF on mechanical, thermal stability and tribological characteristics of EC was examined. The SF used in this study were Kevlar (KK), glass (GG) and carbon (CC). Hand lay-up lamination method was used to develop unhybridised and hybridised epoxy composites. The unhybridised epoxy composite reinforced with BPSF was denoted as BBBB (control). The hybrid of BPSF with KK, GG and CC were designated as BBKK, BBGG, and BBCC, respectively. Mechanical, thermal stability and wear tests were carried out according to ASTM standards. Microstructure evolution was examined with SEM NIXRN (Model 541). The BBCC exhibited higher tensile strength and compressive strength (159.11, 65.21 MPa) when compared to BBGG (141.11, 58.21 MPa), BBKK (144.27, 55.51 MPa), and BBBB (109.38, 52.77 MPa), respectively. The improved hardness in the hybridised samples, BBCC (109.25 BHN), BBKK (89.77 BHN), and BBGG (82.23 BHN), were attributed to the filling of BPSF pores with synthetic reinforcements, when compared to the unhybridised BBBB (78.12 BHN). The BBCC demonstrated highest thermal stability, with a mass residue of 18.00 %. The sample also demonstrated the lowest wear under the tested loads. The microstructures revealed a finely dispersed fibres and better adherence in the matrix as compared to others. The hybridised samples demonstrated better properties compared to the unhybridised. The BBCC, a combination of 2-layer configuration of BPSF and CC exhibited the best mechanical, thermal stability and tribological characteristics. In future research endeavours, an investigation on the synergistic impact of other agro-based natural fibres and synthetic fibres at different configuration of layers on the properties of epoxy-based composites is proposed.
