A. C. (2005), the composite material can be defined as a material consisting of strong carry-load materials (reinforcements) embedded in a relatively weaker material (matrix). The purpose of the reinforcement is to provide the strength stiffness, rigidity and mechanical properties needed to support the structural load. The matrix on the other hand acts to provide a fixed orientation of the reinforcement and in many cases is more brittle. Question 1 Advantages of carbon fibre reinforced polymers

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 of Silicon carbide

At a microscopic level, the constituent materials remain distinct within the finished structure. “Traditional” Composites Wood is a natural composite of cellulose fibers in a lignin matrix. Engineered wood is wood fibers, strands or veneers bound using adhesives.

By choosing an appropriate combination of matrix and reinforcement material, a new material can be made that exactly meets the requirements of a particular application. Composites also provide design flexibility because many of them can be moulded into complex shapes. The downside is often the

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 in the metal alloys, ceramics and polymeric materials” [3]. The main ones focused on in this essay are polymeric matrices, metal matrix composites and ceramic composites
