Aluminium Hybrid Composites are the new group of metal matrix composites (MMCs) due to their attractive properties like high ductility, high conductivity, light weight and high strength to weight ratio and is a response to the dynamic ever-increasing demand of these super material in the field of aircrafts and marines. Carbon Nanotube (CNTs) are also known for their high strength and stiffness and their low density which when combined together makes CNTs an ideal reinforcement. This work briefly reviews the research revelation of an Aluminium (Al-6061) based hybrid metal matrix composite reinforced with CNTs and TiO2. The Hybrid Aluminium Metal Matrix Composites (AMMCs) is prepared with various CNTs weight percentages (0, 0.5, 1 and 1.5 wt. %) and keeping TiO2 weight percentage fixed to 1%.Stir Casting (SC) is focused in general to successfully fabricate the MMCs. The discussion of this work revolves around tensile test, hardness test, and Scanning Electron Microscope (SEM) of the MMC. The mechanical properties of the fabricated MMCs materials like tensile strength, hardness and impact strength is found by using these experimental methods. It has been observed that the tensile strength of the MMCs increases in the presence of TiO2 and CNTs and increases even more with the increase in the weight fraction of CNTs. Same results have been obtained for hardness and impact strength where there is an increase in them in the presence of TiO2 and CNT and their value increases even further with increase in weight fraction of CNTs.

The thermal characterization and analysis of composite materials has been increasingly important in a wide range of applications. The coefficient of thermal expansion (CTE) is one of the most important properties of metal matrix composites (MMCs). Since nearly all MMCs are used in various temperature ranges, measurement of CTE as a function of temperature is necessary in order to know the behavior of the material. In this research paper, the evaluation of CTE or thermal expansivity has been accomplished for Al 6061, silicon carbide and graphite hybrid MMCs from room temperature to [Formula: see text]C. Aluminium-based composites reinforced with silicon carbide and graphite particles have been prepared by stir casting technique. The thermal expansivity behavior of hybrid composites with different percentage compositions of reinforcements has been investigated. The results have indicated that the thermal expansivity of different compositions of hybrid MMCs decrease by the addition of graphite with silicon carbide and Al 6061. Empirical models have been validated for the evaluation of thermal expansivity of composites. Numerical convergence test has been accomplished to investigate the thermal expansion behavior of composites.

Metal matrix composites (MMCs) have been regarded as one of the most principal classifications in composite materials. The thermal characterization of hybrid MMCs has been increasingly important in a wide range of applications. The coefficient of thermal expansion is one of the most important properties of MMCs. Since nearly all MMCs are used in various temperature ranges, measurement of coefficient of thermal expansion (CTE) as a function of temperature is necessary in order to know the behavior of the material. In this research paper, the evaluation of thermal expansivity has been accomplished for Al 6061, silicon carbide ( SiC ) and Graphite ( Gr ) hybrid MMCs from room temperature to 300°C. Aluminum ( Al )-based composites reinforced with SiC and Gr particles have been prepared by stir casting technique. The thermal expansivity behavior of hybrid composites with different percentage compositions of reinforcements has been investigated. The results have indicated that the thermal expansivity of the different compositions of hybrid MMCs decreases by the addition of Gr with SiC and Al 6061. Few empirical models have been validated for the evaluation of thermal expansivity of composites. Using the experimental values namely modulus of elasticity, Poisson's ratio and thermal expansivity, computational investigation has been carried out to evaluate the thermal parameters namely thermal displacement, thermal strain and thermal stress.
