摘要：Metal matrix composites (MMC’s) are made by tailored a reinforcing material into a metal matrix.They are prepared by powder metallurgy and stir casting, although several technical challenges exist with castingtechnology. Achieving a homogeneous distribution of reinforcement within the matrix is one such challenge, and thisaffects directly on the properties and quality of composite.The aluminum alloy composite materials consist of high strength, high stiffness, more thermal stability, morecorrosion and wear resistance, and more fatigue life. Aluminum alloy materials found to be the best alternative with itsunique capacity of designing the materials to give required properties.In the present work a composite is developed by adding fly ash/graphite powder in Aluminum metal by weight ratio5%, 10% and 15. The composite is prepared by stir casting route. Mechanical tests such as tensile test, hardness test,and microstructure test are conducted. It is proposed to use this material for power transmitting elements such as gearswhich are subjected to continuous loading. Finally modeling and finite element analysis of gear is done using Creo 2.0and ANSYS 12.0 Work bench.The contact stress in the mating gears is the key parameter in gear design. Deformation of the gear is also anotherkey parameter which is to be considered. Gears generally fail when the working stress exceeds the maximum stress.This study shows that the complex design problem of spur gear which requires fine software skill for modeling andalso for analyzing. The project aims at the minimization of both contact stress as well as deformation using thecomposite materials. The results of the two dimensional FEM analysis from ANSYS are presented. These stresses werecompared with the theoretical Hertz’s equation values. Both results agree very well. This indicates that the FEM modelis accurate.
