Aluminium Matrix Composites are extensively used due to their desirable properties like low weight, low cost, high strength to weight ratio, good corrosion resistance, good thermal conductivity and high stiffness. Their applications are diversified in production, thermal, marine and automobile industries. Aluminium is extensively used in ships, aircrafts, cars, electrical wires and household utensils because it is abundant in nature. In the present study, Aluminium alloy Al6061 Hybrid Composites reinforced with Boron carbide and Coconut shell ash are fabricated to replace the individual Aluminium alloy Al6061. For that various tests to determine properties such as strength, hardness, wear and corrosion resistance are conducted on composite samples which make them fit to be used in aircraft window frames by reviewing various literatures. In addition to above, machinability analysis is performed on all the specimens and their surface roughness is measured. Based on the results obtained, we can come to a conclusion that the aluminium composite has superior properties than individual Al6061 alloy.

The investigation of this research work study the potential grains of quarry dust (QD), fly ash (FA) and silicon carbide (Sic) as a reinforcements of this hybrid metal matrix composite. In this al-6063 alloy metal matrix hybrid composite the quantity consist of 4wt%, 6wt%, and 8wt% QD-FA-SIC respectively. The Brinell hardness, tensile nature, and compression of those hybrid composites has explore the results according to ASTM grades. The particle size, grain structural boundaries have been investigate by the help of computerized inverted metallurgical microscope. Influence of quarry dust and fly ash in the hybrid metal matrix composites has the good metallurgical and mechanical properties than unreinforced matrix. For the comparison of these, of reinforced the properties of unreinforced matrix to reinforced hybrid composite was evaluated under dry laboratory conditions.
The properties of MMCs enhance their handling in automotive and various applications for the reason that of encouraging properties of high stiffness and high strength, low density, high electrical and thermal conductivity, corrosion resistance, improved wear resistance etc. Metal Matrix Composites are a vital family of materials designed at achieving an improved combination of properties. Our paper deals through to fabricate Hybrid Composite by heating Al 2024 in furnace at a temperature of around 4000 C. E-Glass fiber & Fly ash will be added to the molten metal with changing weight fractions and stirred strongly. Then the ensuing composition will poured into the mould to obtain hybrid composite casting. Aluminium alloy (2024) is the matrix metal used in the present investigation. Fly ash and e-glass are used as the reinforced materials to produce the composite by stir casting. Fly ash is selected because of it is less expensive and low density reinforcement available in great quantities as solid disposal from thermal power plants. The Test specimen is prepared as per ASTM standards size by machining operations to conduct Tensile, Compression, Hardness, and wear test. The test specimens are furnished for tensile, compression strength and wear as per ASTM standard E8, E9 and G99 respectively using Universal Testing Machine and pin on disk machine. It is seen that the fabricated MMC obtained has got enhanced mechanical strength.

This work reveals the evaluated results of some of the mechanical properties, such as tensile strength, compression strength, hardness and microstructure, of Aluminium alloy (Al6061) was reinforced with Fly ash as primary reinforcement and mica as secondary reinforcement for different ratios. The reinforcement of fly ash varied in the interval of 0%, 2%, 4%, and 6%. Keeping Mica as constant. Bottom pouring stir casting method is adopted for casting the composite materials. The test tokens were prepared according to ASTM standard (E8M-13A). The test was conducted and result was recorded. Tensile test, compressive test, hardness test and microstructure studies was evaluated and their results are recorded.
The objective of present investigation is to study the effect of reinforcements on the Mechanical properties of E-Glass short fibres and Flyash reinforced Al 8011 hybrid. The alloy of Al 8011 reinforced with E-glass and fly ash particulates are prepared by using graphite die for casting. The MMC is obtained for different composition of E-glass and flyash particulates (varying E-glass with constant fly ash and varying flyash with constant E-glass percentage). The test specimens are prepared as per ASTM standard to conduct tensile and compression tests
