“…Al-TiB2 metal matrix composites were fabricated using the in-situ method, and optimization techniques like the grey relational approach and the Taguchi L9 orthogonal array method were used. The optimized physical and mechanical properties results were discussed [19][20][21][22]. Al-SiC -kaoline hybrid metal matrix composite was fabricated by using the powder metallurgy technique.…”

The modern Aluminium based composites have a great demand in the field of aerospace applications due to their lightweight, high strength, high stiffness, and superior mechanical properties. The main objective is to fabricate the AA2195 composites through Medium Frequency Induction Furnace (MFIF) with Taguchi L16 design of experiments, hot rolling process and heat treatment of composites is done and then compare the mechanical properties of hot rolled and heat treated AA2195 composite with casted composite. It is analyzed the effects of reinforcements like graphite and boron carbide on the mechanical behaviors and microstructure of both AA2195 composites. The microstructures revealed that reinforcements were distributed uniformly throughout the composites. It observed that the elemental investigation on SEM and XRD for both the composites showed that formed intermetallic compounds (IMCs) helped refine the microstructure and further increased the mechanical properties. The hot rolled and heat-treated AA2195 composite fabricated at 8% B4C and 6% Gr exhibits the more enhanced ultimate tensile strength, hardness, and reduction in density, % elongation compared to the casted composite. The rolling process is used to reduce the porosity of the composite. In contrast, heat treatment enhances the composite's mechanical properties like strength and hardness.

“…In addition to their exceptional qualities, they are readily available and less expensive than some other common oxides. [ 13 ] In general, surface‐modified particles and fibers can improve the mechanical and thermal properties of polymer matrix composites compared to untreated particles and fibers. Additionally, the dispersion of particles uniformly tends to react strongly with the polymer matrix as well as natural fiber like okra is easily available, extraction and production are also cheaper hence all these materials are used in this study.…”

In this present study, a natural fiber-based fiber metal laminate (FML) was fabricated for various engineering applications. The primary aim of this present investigation was to study the effect of adding natural fiber along with metal and the effect of the surface-treatment process on the reinforcements on load-bearing and thermo-mechanical properties. Okra fiber woven mat, aluminum 2024-T3 foil and rice husk-derived biosilica were used as reinforcements.For surface treatment, the metal foil was sandblasted whereas the okra fiber and biosilica were silane-treated. The FML was fabricated using the vacuum bag method utilizing as-received and silane-treated reinforcements as two separate models. According to the results, the addition of Al foil and okra fiber improved the storage modulus and loss factor of about 4.2 GPa and 0.39 for surface-treated reinforcements. Similarly, maximum fracture toughness and energy release of 39.42 MPa √m and 0.76 MJ/m 2 for surface-treated EOA2 composite designation. Moreover, the addition of okra fiber and Al foil increased the fatigue life counts up to 54,266, 48,116, and 26,263 for surfacetreated EOA2 composite at 30%, 60%, and 90% of ultimate tensile stress (UTS).Such thermo-mechanical and load-bearing properties improved FMLs could be used in automotive, aircraft, drone and other industrial applications requiring high structural rigidity and load absorbing capability.

Aluminum matrix composites have gained interest recently because they are more efficient, lighter, and less expensive. The purpose of this current study was to examine the effects of various casting operating conditions, including stirring temperature, stirring time, and stirring speed, on the casting process. Determining the optimum processing parameters to achieve significant outcomes could be the most daunting problem while casting a specimen. Box-Behnken design based on response surface methods was used to investigate the effects of stir casting factors on the mechanical properties of AA6063 - 4 % TiB2 composites. The response's real value, which includes hardness before heat treatment, hardness after heat treatment, and tensile strength, is reflected in the surface plot created by statistical software. F-ratio is often used in an ANOVA table to examine how operational variables affect properties of the material. Dispersion of the reinforcements mixture has been studied and characterized under scanning electron microscope and x-ray diffraction spectrometer. The optimum temperature, time, and rotational speed were 823.662°C, 15 minutes, and 300 rpm. Composite materials made from aluminium 6063 are extensively used in the fabrication of lightweight aircraft components like ribs and fuselages.
