Nowadays, the usage of metal matrix composites is increased in aero space, automotive, marine, electronic and manufacturing industries. Aluminum metal matrix composites have attained significant attention due to their good mechanical properties like strength, stiffness, abrasion and impact resistant, corrosion resistance. When compared to the conventional materials Aluminum Silicon Carbide (AlSiC) hybrid materials available in minimum cost. In the present study, based on the literature review, the individual Silicon Carbide with aluminum and combined influence of Silicon Carbide with graphite reinforcements Aluminium Metal Matrix Composites and Silicon Carbide with mica reinforcement Aluminum is studied. The monolithic composite materials are combined in different compositions by stir casting fabrication techniques, to produce composite materials. The literature review framework in this paper provides a clear overview of the usage of Graphite and Mica as a reinforcing agent in different composition matrices along with its distinctive performances.

Abstract In this paper, the combined effect of different weight percentages of silicon carbide (SiC) and graphite (Gr) reinforcement on the mechanical properties of polyamide (PA6) composite is studied. Test specimens of pure PA6, 85 wt% PA6+10 wt% SiC+5 wt% Gr and 85 wt% PA6+5 wt% SiC+10 wt% Gr are prepared using an injection molding machine. The tensile, impact, hardness, morphology and thermal properties of the injection molded composites were investigated. The obtained results showed that mechanical properties, such as tensile and impact strength and modulus of the PA6 composites, were significantly higher than the pure PA6, and hybridization with silicon carbide and graphite further enhanced the performance properties, as well as the thermal resistance of the composites. The tensile fracture morphology and the characterization of PA6 polymer composites were observed by scanning electron microscope (SEM) and Fourier transform infrared spectroscopic methods. SEM observation of the fracture surfaces showed the fine dispersion of SiC and Gr for strong interfacial adhesion between fibers and matrix. The individual and combined reinforcing effects of silicon carbide and graphite on the mechanical properties of PA6 hybrid composites were compared and interpreted in this study. Improved mechanical properties were observed by the addition of small amount of SiC and Gr concurrently reinforced with the pure PA6. Finally, thermogravimetric analysis showed that the heat resistance of the composites tended to increase with increasing silicon carbide and graphite content simultaneously.
