The main objective of this experimental examination is to accentuate the salient effect of mixtures viz., E-glass and Fly ash based on the characterization of prominent mechanical properties of Al 8011 hybrid amalgamated composites. The prominent alloy Al-8011 amalgamated with particulates of E-glass and fly ash materials have been fabricated by using graphite die for the method of casting. The metal matrix composite is fabricated for dissimilar configuration of the particulates of E-glass and fly-ash by changing E-glass with constant fly ash. The hybrid composite samples have been fabricated as per genuine prerequisite of ASTM standards or conditions to accomplish pertinent tensile and compression tests.

This paper presents the investigation of moderate properties of solidified Al (LM6)+SiCp metal matrix composite (AMMC). These AMMC is fabricated by considering five different parts of casting and different weight of SiCp for reinforcement. The SiCp wt. % is varied from 5 wt. % to 15 wt. % with a step size 5 %. During casting, temperature is measured using K-thermocouple and temperature vs. solidification curve is traced. These results are compared with the solidification results of Al (LM6) alloy. It is observed that the solidifying duration of AMMC increased as well as decreased liquid temperature by adding SiCp to it. The trend of the curve is also presented that the cooling rate and the duration of solidification are different for different part of casting. Mechanical property of the each five parts of casting is tabulated. It is observed from the properties that the mechanical properties of AMMC increased by increasing the wt. % of the reinforced particles SiCp.

This paper presents the development and characterization of aluminium alloy 6063 based metal matrix composite with varying combinations of fly ash and Borosilicate reinforcements.  In the present work, the aluminium alloy 6063 (AA) is taken at a constant 84 vol% while the reinforcements Fly Ash (FA) and Borosilicate (B) are varied in the proportions of 2%, 4% 8%, 125 and 14%. Six samples were fabricated by stir casting and the mechanical properties were analyzed using tensile test, hardness test and wear test while the microstructure is analyzed by obtaining SEM and EDX images of the specimen. It is seen that both the reinforcements used in this study, increased the tensile and wear resistance of the alloy. The desirable mechanical and micro structural properties were found to be in the specimen with 84% AA, 14% FA and 2% B. The tensile strength of the aluminum alloy at this desirable combination is found to increase by 11.97%, ductility by 36.75% and the wear resistance by 62%.  This metal matrix composite of AA6063 with fly ash and Borosilicate reinforcements can be used in automobile, aerospace and structural applications where wear resistance and tensile properties are mainly required.

PurposeFiber-reinforced polymers (FRP) contain critical electrical conductivity for high-intensity radiated fields such as lightning strike susceptibility, electromagnetic energy from radar, airborne radio frequency transmitter. To provide high-intensity radiated field protection (HIRFP) for the electric and electronic aircraft system and defied the EMI effect on it, metal matrix composite was conquered. To provide the dynamic ever-increasing requirement of industries, it is necessary that Al6061 metal matrix composite assisted with AL2O3 and fly ash is used to construct the aircraft to provide HIRFP. The thickness of the material can be maintained as low as possible to use it as a coating material for the aircraft surface. X-band for oblique incidence is used to measure electromagnetic and mechanical safeguarding properties of composites.Design/methodology/approachDay by day, the applications of aerospace are becoming digital and automated. Proper shielding techniques are required to operate digital electronic devices without electromagnetic interference. It leads to a rapid rise in temperature, thermal ablation, delamination, and adverse effects on the electric and electronic aircraft system. Fly ash, a metal matrix material composite AL6061 with different percentages of reinforcement of Al2O3, was contemplated and experimented with for mechanical properties like tensile strength, density and hardness.FindingsThe obtained results compared with adjusted values and an improvement of 0.19, 0.18, 0.14 g/cm3 for density of MMC-1, MMC-2, MMC-3.31, 11 MPa for tensile strength of MMC-1, MMC-2. 24, 27, 23 BHN for hardness of MMC-1, MMC-2, MMC-3. With regard to the shielding effectiveness the results compared with adjusted values and obtained 11.36, 14.56, 19.47 dB better value than it. According to the above results, fabricated MMC’s provide superior results for a defined application like HIRFP(Surface material of aircraft).Practical implicationsIt can be used to protect electronic devices under a high-intensity radiated field, mainly in aircraft design to protect from lightning effect.Originality/valueFor a better approximation of the signal toward the practical case, the oblique incidence was considered with a different combination of Al2O3 and fly ash, reinforced to pure AL6061 to get better shielding and mechanical properties.

Stir Casting

The aluminium based composites are increasingly being used in the transport, aerospace, marine, automobile and mineral processing industries. The widely used reinforcing materials for these composites are silicon carbide, aluminium oxide and graphite in the form of particles or whiskers. In this study Al6061-6 & 4wt% Al2O3 based metal matrix composite were produced by mechanical stir casting process. The obtained cast metal matrix composite is carefully machined to prepare the test specimens for hardness, tensile as well as fracture toughness studies as per ASTM standards. The hardness, tensile strength and fracture toughness properties of Al6061-Al2O3 composites are explored experimentally. Finally compare the material characterization with heat treatment process sample and compare the fracture toughness of sample with mathematical approach, experimental and finite element method.
