Despite the several disadvantages, the material selection and its design can evade most of the failings. New research and the improvement in the technologies have resulted in the development of new matrices and reinforcing fibers which have produced new composites having exceptional properties. The newly developed composites are lighter in weight and more efficient then their metallic counterparts, and so have emerged as the key materials for futuristic use. For example, in aviation industry, the fiber reinforced composites are used in the structural applications, while they are also used in the processing of civil infrastructures, including power long span bridges, generating wind mills, earthquake proof highway supports, etc. However, their higher initial cost is the key barrier for wide utilization. The utility of a material over its life cycle in commercial industry is mainly decided by its overall cost and is also the main reason for inhibiting the research of new materials. The recycling of the composite materials is also a growing concern in industry which produces millions of parts per year, such as automotive industry. Also, with the new government policies into practice and rising environmental problems, the utilization of composite is concerning for its problematic recycling.
