Abstract: - Composite materials are replacing the materials used in various fields and are the candidate materials for future growth. Metal matrix composites are the class of composite materials finding vast applications in automotive, aircraft, defense, sports and appliance industries. The reason for this is their exciting properties like high specific strength, stiffness, hardness, wear resistance, dimensional stability and designer flexibility. The present work of Al-Sic particulate composites with 10%, 20%, 30% of Sic fabricated through stir casting process.

The main objective of this project is to analyze the exhaust valve characteristics by determining deformation, stress, frequency and heat flux. The finite element analysis is carried to compare materials AISI 4340 Steel with Al-Sic Al-Sic particulate composites with 10%, 20%, 30% of Sic. The better material for exhaust valve is determined from the results of analysis.3D model of exhaust valve is done in Creo 6.0. Static Structural, Thermal and Modal analyses are performed in ANSYS.
