Since its beginning, Human is always try to sustainable actions in all the direction associated with human. It’s may be for energy saving, environment protection, reduce to effort, cost reducing and so on. It’s also applicable in case of composite. Intensively developed polymer composite materials (PCM) are used in different sectors of industry and technology. They are successfully replacing traditional construction materials and also permit the conditions that exclude use of metals. One of the basic reinforcing elements of composite materials is fibers. A composite is a material, that consist of at least two material macroscopically, that work together to achieve the better and favorable properties [1] from the previous materials. In the composite these components do not dissolve into each other and remain visible macroscopically. The main purpose of this paper to investigate the mechanical strength of Carbon fiber reinforced metal matrix composite (CFR-MMC) and compare with mechanical strength of Basalt fiber reinforced metal matrix composite (BFR-MMC). The investigated specimen is composed of aluminum oxide and carbon fiber and compare the mechanical strength of (CFR-MMC) with Basalt fiber reinforced metal matrix composite (BFR-MMC). To investigate the mechanical strength there is mainly do two strength test i.e. compressive strength, tensile strength on the universal testing machine and analysis specimen deformation and their load Vs displacement curve. With the help of load-displacement curve, we will be able to conclude the behavior and strength of investigated specimen and their functionality and applications areas.
