Abstract

Use of light weight structures demands lot of commercial aspects correlation with enhancement of properties offer unique applications which directs to develop new age materials which might be originating from the polymers, metals, ceramics to conclude the effective utilization of material to satisfy end user. The Role of lightweight materials in many industries and research fields is to accelerate the need of finding dynamic combinations to excel the most desirable commercial aspects owning to its light weight, high strength, higher hardness, wear resistance, durability. Graphene based materials offer better platform to innovate lighter and stiffer and tougher materials. Unlike other materials graphene weighs very lighter and stronger stimulate to use this as a major reinforcing material with most flexible matrix is aluminum. Significantly graphene is the only material available in two-dimensional structure which yields better mechanical properties like strength and hardness. To aid the easy preparation of metal matrix composites a well-known technique called stir casting technique is normally employed. By keeping this objective, the present work involves the synthesis of graphene reinforced aluminum based metal matrix composites with the help of stir casting process. The aluminum powder used here is 7075 grade which is meant for aerospace structure to retain as better matrix material. Graphene is added to aluminum matrix with 0.5%, 1%, 1.5%, and 2.0% by weight of the matrix considered. Compression test has been performed for all the prepared samples with the help digital UTM. It is found that sample filled with 0.5% of graphene shows excellent resistance to compressive loading Which records maximum strain of 0.60025 against applied break load of 222KN which are concluded to be better compared to the rest of the samples.
