Fiber Reinforced Polymer (FRP) is a composite material technology that is strong, lightweight, corrosion-resistant and maintenance-free. The material consists of fiber reinforcements surrounded by polymer resins. The fiber reinforcements provide the strength and stiffness to the composite material. The polymer supports the fibers so they can do their job, and protects the fibers from chemicals and UV radiation.
The fiber reinforcements provide the strength and stiffness to the composite material. Fiberglass is the most common reinforcement since it has high strength and good stiffness at a reasonable cost. When higher stiffness is needed for the best weight savings, carbon fiber is used even though it costs more.
There are many processes for manufacturing FRP parts. Deciding the right process takes many factors into consideration: size, shape, quantity, production rate, type of fiber and resin, cosmetics, tolerances and cost. Processes include Pultrusion, Vacuum Infusion, Filament Winding and Hand Layup.
