FRP rebar is composed of a polymer matrix reinforced with fibers, typically glass, carbon, or aramid. This unique combination results in a material that is both lightweight and exceptionally strong, making it an attractive alternative to traditional steel rebar. One of the most notable characteristics of FRP rebar is its high tensile strength-to-weight ratio, which allows for easier handling and installation on job sites. Unlike steel, which can corrode over time when exposed to moisture and chemicals, FRP rebar boasts excellent resistance to corrosion and environmental degradation, leading to extended service life and reduced maintenance costs.
