Composite material is one such option that which can be explored and utilized in Manufacturing, aerospace, defence, automobile sectors. Therefore, in this research work a powder compaction die is designed and fabricated through WEDM process and synthesized Copper- 4 wt% TiC- 3 wt% Graphite matrix composite was reinforced with different percentages of SiC (3, 6 and 9 wt %) through blending, followed by compaction and sintering. Hardness and compressive strength results were carried out for those specimens and finally concluded that the hardness of the specimens increased with increase in SiC weight percentage in the composition and 6 wt% SiC shows the high compressive strength among remaining compositions. This copper matrix hybrid composite have extensive applications in manufacturing of bushes and bearings, heat transfer conductors, high conductivity electrical contactors and so on. Key Words: Hybrid Composite, Sintering, TiC, SiC. 1. INTRODUCTION Recently new materials have taken the important position in engineering field. Those materials fulfill the demand of almost all engineering applications maintaining tremendous mechanical and physical properties. In present situation, various scientists and researchers have developed the unavoidable compatible new engineering materials. Various materials have been combined with each other and give intended properties in each and every part of the world i.e. the development of new materials give another unique property and are different from their base materials. 1.1 Introduction to Composite Materials A composite material can be defined as combination of two or more materials that results in better properties than those of the individual components used alone. In contrast to metallic alloys, each material retains its separate chemical, physical and mechanical properties. The two constituents are as reinforcement and a matrix. The main advantages of composite materials are their high strength and stiffness, combined with low density, when compared with bulk materials, allowing for a weight reduction in the finished part [1]. Metal matrix composite (MMCs) have attained growing importance because of their potential applications in the automobile, aerospace, sporting goods and general engineering industries due to their excellent properties (e.g., high specific strength, elastic modulus, specific stiffness, desirable coefficient of thermal expansion, elevated temperature resistance and superior wear resistance) [2]. 1.2 Introduction to manufacturing of composites There are some different manufacturing processes that are available to manufacture new type of composites. They are given below:  Solid state processing  Liquid state processing  Plasma arc cutting  Hand layup processing  Spray up processing  Resin transfer molding  Pultrusion processing  Pressure bag molding  Compression molding. 1.3 Importance and Selection of Manufacturing Processes: Manufacturing is a series of complex interaction between materials, machines, energy and people. It begins with creation of individual parts that are finally assembled to produce final product. Every method of production uses its own basic principles for impacting desired shape, accuracy and surface finish. There are many factors involved in selection of appropriate manufacturing process. However, the selection is usually made on the basis of the following considerations: 1. Materials to be used 2. Shape and size of the components 3. Accuracy and surface finish 4. Volume of production 5. Economy [3]. Though there are many different type of manufacturing processes, Powder metallurgy is the best option to
