Aluminium remains the most utilized metallic alloy as matrix material in the development of MMCs and the reasons for this has been reported [6,9,10]. The common metallic alloys utilized are alloys of light metals Al, Mg and Ti however, other metallic alloys like zinc Zn , copper Cu and stainless steel have been used [7,8]. Aluminium matrix hybrid composites: The final properties of the hybrid reinforcement depend on individual properties of the reinforcement selected and the matrix alloy [10,28,29]. The results obtained from the investigations carried out on these alternative reinforcements have been promising as they show significant improvement in the properties of the composites developed over the unreinforced alloy. Some authors have reported comparable or improved performance of hybrid AMCs over single reinforced AMCs even at reduced processing cost [2,27].

The slight reduction in yield strength, ultimate tensile strength and hardness was attributed to lower hardness value husk amc-105 silica, which is the predominant compound in the rice husk ash. This is aimed at providing solution to problems posed by high cost and husk amc-105 availability of conventional ceramic reinforcements [14—17]. Ductility and fracture toughness are important material properties that are necessary for preventing failures under husk amc-105 stress or shock load applications.
Finally, there is need for more research investigation to harness the benefits of the recently developed friction stir processed surface AMCs and bulk AMCs. Cast aluminum-matrix composites for automotive applications.
As mentioned earlier, corrosion performance of these AMCs are also not consistent judging from husk amc-105 published in the past [30,31]. The adhesion of debris on the surface of the husk amc-105 increased the coefficient of friction and the wear rate.

This was attributed to the lower hardness and elastic modulus of silica present in the RHA as compared husk amc-105 the hardness of the silicon carbide. Mater Des, 28pp.
Resour Amc1-05 Recycl, 75pp. An overview of the recent studies on AMCs reinforced with agro waste derivatives and synthetic ceramic particulates is presented below.
The direct involves load transfer from the softer matrix to the hard ceramic particulates while the indirect mechanism involves husk amc-105 generation of high dislocation density due to thermal mismatch between the coefficient of thermal expansion CTE of the matrix and reinforcement during the production process. However, Fourier transformed infra red spectroscopy FTIR revealed that the aluminium carbide phase was formed in the bulk composites due to the reaction between the carbon of the FA husk amc-105 molten aluminium.
