Recent developments in the field of fiber reinforced composites (FRCs) have resulted in the development of highly efficient construction materials. They have been successfully used in a variety of industries such as aerospace, automobile and ship building The FRCs are unaffected by electro-mechanical deterioration and can resist corrosive effects of acids, alkalis, salts and similar aggregates under a wide range of temperatures. FRCs thus hold a very distinct advantage over steel plates as an external reinforcing device. Moreover, FRCs are available in the form of laminas and different thickness and orientation can be given to different layers to tailor its strength according to specific requirements.
• Plates -at a face to improve the tension capacity.
• Bars -as reinforcement in beams and slabs replacing the steel bars.
• Cables -as tendons and post tension members in suspension and bridge girders.
• Wraps -around concrete members to confine concrete and improve the compressive strength.
