e-mail: madhavan.tes@gmail.com Abstract Aluminum silicon carbide Metal Matrix Composites (Al-MMC) are widely used in aeronautical and automobile industries due to their excellent mechanical and physical properties. However machining this composites find difficult because of the reinforcement particles. Tools wear more quickly and reduce the life of the tool. This paper presents the experimental investigation on machining two different A356 matrix metal reinforced with 10 % and 20 % by weight

Abstract Friction stir processing (FSP) has been applied by several researchers to produce surface modification of metallic materials. The feasibility to produce TiC and B4C particle reinforced aluminum (AA6360) hybrid matrix composites (AHMCs) were studied in this paper. The measured content of TiC and B4C powders were compacted into a groove of 0.5 mm X 5 mm. Double pass FSP was carried out using a FSW tool at rotational speed of 1600 rpm, processing speed of 60 mm/min and axial force of 8 kN

The use of Composite Materials in Aerospace, Wind Power and Automotive Technologies Introduction A composite is a multiphase heterogeneous material comprising of fibres that are embedded in a matrix [1], [2]. A composite is unlike an alloy because in an alloy, the other components have been produced by naturally occurring changes. There is a diversity of types of composites currently available, since “it is possible to design materials with property combinations that are better than those found
