Today's technological progress is due to sophistication in materials.As the technology becomes more and more advanced, the materials used have to be reliable and more efficient in performance. Materials should be light in weight, strong, tough, wear resistant and capable of withstanding extreme operating environments such as high temperature, pressure, cryogenic conditions, high vacuum, highly corrosive and in some cases electric, magnetic or irradiation fields. No individual material is capable of meeting these demands. Thus it is necessary that the material system should preferably be designed for specific end use (tailor-made) necessitating a combination of desired properties. This has resulted in the development of advanced materials and composites form one class of such materials. Composites represent a combination of at least two chemically distinct materials with a distinct interface separating the constituents. These are three kinds of composites: Polymeric matrix (PMC such as FRP), Metal matrix (MMC) and Ceramic matrix (CMC) materials. Their high strength to weight ratio, enhanced resistance to environmental hazards, lower density, high fatigue resistance, wear resistance and related properties has widened the range of application leading to large scale substitution of conventional engineering materials for aerospace to consumer goods.
