FRP composite materials are comprised of high strength continuous fibers, such as glass, carbon, or steel wires, embedded in a polymer matrix. The fibers provide the main reinforcing elements while the polymer matrix (epoxy resins) acts as a binder, protects the fibers, and transfers loads to and between the fibers. FRP composites can be manufactured on site using the wet lay-up process in which a dry fabric, made of carbon or glass, is impregnated with epoxy and bonded to prepared concrete substrateSee more on structuremag.orgSTRENGTHENING OF REINFORCED CONCRETE BEAMS carbon fibre fabric strips are used to strengthen the reinforced concrete beams in shear. The experimental study consists of two control beams and eight strengthened RC beams.
