Study of application and advances of composit materials

Two or more chemically different constituents combined macroscopically to yield a useful material which is called composite material. One constituent is called reinforcing phase and the one in which the reinforcing phase is embedded is called matrix.

Composite materials have changed all the material engineering. The development of composite materials has given a new direction to engineers to use better materials resulting in cost reduction, increase efficiency and better utilization of available resources. Composite materials have endless engineering application where strength to weight ratio, low cost and easy fabrication are required. For many critical applications, the use of composite materials in comparison to metals has resulted in savings of both weight and cost. Some examples are aerospace applications, cascades for engines, leaf spring, curved fairing and fillets, replacements for welded metallic parts, ducts, tubes, cylinders, blade containment bands, biomedical devices, electronic devices, sports goods etc. In aerospace approximately 50% of the parts are made from composites due to their high specific strength, light weight and stiffness. Many composites used today are the leaders of materials technology, with performance and costs appropriate to ultra demanding applications. This paper presents the current study of application of composites in industries and finds the approach of composite material in future direction with its advantages-disadvantages and applications in industries. This paper also presents the Properties, Characteristics, Challenges, Opportunities and Future demand of Composite material for advance industrial application.
