A Composite material is a type of material fabricated from two or more different materials with different physical and chemical properties that with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. In this, one phase of composite is continuous, this is called matrix and discrete phase is called reinforcement or fiber. Compared to matrix material the fiber material has better mechanical properties (tensile strength, Youngs modulus, hardness, etc.). This material may be preferred for many reasons: common examples include materials which are stronger, lighter and less expensive when compared to traditional materials like metals. Main advantage of composites with polymer matrix is the synergic combination of easily formable fluid resin with firmness and toughness of supporting fibres. Synergic combination means that characteristics of composite materials are better accordingly proportional characteristics of individual components. Quality of matrix – support interface is of virtual importance resulting material properties. Composites are made in such a way to maximize the synergic effect. The main classifications of composites are based on matrix material, which are ceramic matrix composites, polymer matrix composite, metal matrix composites and based on reinforcement are fiber reinforced composites, particulate composites, and structural composites. Present days the increasing use of composite materials has seen their application spread to larger and more safety critical components and structures, with long service capability.
