FRP stands for Fiber Reinforced Plastic, which is a composite material made of a polymer matrix reinforced with fibers. The fibers are typically glass, carbon, or aramid, and the polymer matrix can be a thermoset such as polyester or epoxy, or a thermoplastic such as polypropylene or nylon. FRP is known for its high strength-to-weight ratio, corrosion resistance, and durability, making it a popular choice for applications such as aerospace, automotive, construction, and marine industries.
