This composite fiber field has good formability, wide spread, renewable, cost-effective and eco-friendly features. This research paper sets an outline on aluminium alloys and its composites energized as a part of various commercial and engineering applications. In this paper, illustrations were taken from many articles that supports these applications of natural fiber which reinforced polymer composites. These composites give the fundamental dates’ about the usage of natural fibers and its composite materials, mechanical, structural and physical properties. The requirement of light, inexpensive and quickly processed materials has increased to a great extent. The Al/SiC metal matrix composites have light weight, wear confrontation and high elastic modulus. The Al/SiC metal matrix composite has applications in many industries. In the present study, Aluminium based metal matrix composite is primed using stir casting method. The main objective is to evaluate the ultimate tensile strength, hardness and compressive strength of SiC particulate reinforced Al matrix composites as a function of volume of SiC. The specimens made were tested on universal testing machine, Rockwell hardness tester. The effect of weight percentages of SiC in the metal matrix composites on ultimate tensile strength, hardness and the compressive strength is studied.

Aluminium usage in automotive applications has full-fledged substantially in due course of time. There are strong predictions for aluminium applications in hoods, trunk lids and door hangings on a steel frame. As a main point, the material for the engine block, which is a significant part of the automobile sector is switched from the iron cast to aluminium finding in the decrease of weight. A modern car with components made of aluminium alloy can be 24% lighter than one with components made of steel. Today, aluminium is the second most used material (in % terms) of the total weight of the car. It is used to make components of the suspension, the chassis, cylinder blocks and other engine components.
