Many of common materials (metals, alloys, doped ceramics and polymers mixed with additives) also have a small amount of dispersed phases in their structures, however they are not considered as composite materials since their properties are similar to those of their base constituents (physical property of steel are similar to those of pure iron). Favorable properties of composites materials are high stiffness and high strength, low density, high temperature stability, high electrical and thermal conductivity, adjustable coefficient of thermal expansion, corrosion resistance, improved wear resistance etc THE PRESENT PAPER DEALS WITH- To produce Hybrid Composite by heating Al 2219 in electrical resistance furnace at a temperature of 700 0 C. E Glass fiber & Fly ash will be added to the molten metal with varying weight fractions i.e., Al 2219 and stirred well. Then the resulting mixture will poured into the mould to get hybrid composite casting. The obtained Castings will be machined in order to get the specimens of required dimensions as per the ASTM Standards.
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.

This paper has a propensity to identify low cost and ordinarily available reinforcements besides comparatively reviewing fly ash, bagasse ash, rice husk ash reinforced aluminium composites. This has led to microstructure, mechanical and wear characteristic investigation of newer composite developed through stir casting with cenosphere, rock dust and e-waste cathode ray tube (CRT) panel glass powder. Comparison over experimental results with available reported data of said reinforcements clarifies that newer reinforcements have also yielded equivalent properties. Addition of these newer reinforcements up to 10% increases the tensile strength whereas maximum of 65.12% hardness raise is attained for cenosphere and 63.04% for CRT addition to that of Al 6061 T6. Tensile strength increases up to 9.84% for 15% cenosphere reinforcement, 9.02% for 10% CRT addition. Addition of cenosphere and rock dust up to 15% increases the wear resistance but in the case of CRT powder, wear resistance is h...
In this present investigation efforts are made to study the mechanical properties of as cast Mica particulates and Short E-glass fibers reinforced AA7075 Hybrid composites containing mica particulate of 200 microns and short E-Glass fibers of 2-3 mm length in different compositions. The vortex method of stir casting was employed, in which the reinforcements were introduced into the vortex created by the molten metal by means of mechanical stirrer. Castings were machined to the ASTM standards on a highly sophisticated lathe. The degree of improvement of mechanical properties of MMCs is strongly dependent on the kind of reinforcement. An improved mechanical properties occurs on reinforced compared to Unreinforced MMCs alloys.

Aluminium alloy materials found to be the best alternative with its unique capacity of designing the material to give required properties. Aluminium alloy metal matrix composites (MMCs) are gaining wide spread acceptance for automobile, industrial and aerospace application because of their low density, high strength and good structural rigidity. In the present work, an attempt is made to prepare and study the mechanical properties of Al6061- E-glass fiber Composite. The Al6061- E-glass fiber having 2wt%, 4wt%, 6wt%, 8wt% and 10wt% were fabricated by liquid metallurgy (stir cast) method. The ingots were subjected to T6 heat treatment to optimize the properties. The composite specimens were machined as per ASTM test standards. The microstructures of the composites were studied to know the dispersion of the E-Glass fiber in matrix. It has been observed that addition of E-Glass fiber significantly improves ultimate tensile strength along with compressive strength and hardness properties as compared with that of unreinforced matrix.
In the development of materials, the main objective is to reduce the weight and to have maintenance free materials with good mechanical properties these requirements are fulfilled by composite materials. In this work, carbon/abaca/kenaf fiber is fabricated by fly ash 3%, 4% and 5% mixed with epoxy resin. The mechanical characterization of the prepared composite materials are investigated experimentally. The low-velocity impact tests are performed by Charpy test method and tensile test and flexural test are performed by using a universal testing machine. The impact contact force and the tensile strength are accurately estimated using the experimental analysis method. The result showed that 3% fly ash composite had more strength compared to 4% and 5% fly ash composite.
