Fiber-reinforced polymer (FRP) composites are typically made of fibers like glass, aramid, or carbon in a polyester or vinyl ester resin matrix. FRP bars are being researched to replace steel reinforcement in concrete as steel is susceptible to corrosion which reduces the lifespan of concrete structures. FRP composites are corrosion resistant, lightweight, and strong. They offer easy construction and handling and have applications in new FRP bridge decks, concrete decks with FRP rebar, and strengthening existing structures. However, FRP composites are still under testing and research as connections are difficult and the fibers cannot be easily bent in the field without losing strength. More design work is needed for this material.
