This paper deals with the reduction of weight ratio in the wing structure improves the efficiency and performance of an aircraft wing. Amongst all the aircraft parts reduction in the weight of the wing has got higher importance. Generally an aircraft wing structures are design using pure aluminium, but in this project composite material which is a combination of Aluminium LM25 (AL) and Silicon Carbide (SiC) where in aluminium is the base metal and silicon carbide is reinforcement is used to reduce the weight ratio of the wing structure. By varying silicon carbide percentages in aluminium25 four types of specimens are prepared using stir casting process. The young’s modulus, Poisson’s ratio and density of each specimen are determined experimentally by subjecting the specimen to compression test, hardness test and tensile test. By comparing the material properties obtained experimentally optimum percentage of silicon carbide in aluminium is determined. A suitable wing profile NACA 4412 is selected and modelled in CATIAV5 R20. The generated wing profile is imported to ANSYS WORKBENCH. Static structural analysis is carried out in ANSYS by inputting the properties of the optimum specimen which are obtained experimentally. Similarly by in putting pure AL25 properties. The results obtained from ANSYS for pure AL25 and metal matrix composite (SiC) are compared. By comparing the results it is found that composite material has better material properties and stresses than pure aluminium.
