ABSTRACT
Composites are materials made by the synergistic assembly of two or more constituting materials (matrix and reinforcement), engineered in such a way that they form a single component and yet can be distinguished on a macroscopic level. Matrix encases the reinforcements and acts as a binder for the fi bers. Additionally, the matrix holds the reinforcements in a fi xed position and the reinforcement enhances the properties of the composite system by imparting its mechanical and physical properties. Composite materials can be engineered with desired properties by choosing and varying the concentration of diff erent types of matrices and reinforcements. Th e durability of composites is very high; they have very high strength to weight ratios, are resistant to environmental corrosion, and provide ease of use concept.
