Which is a structural fiber and a plastic, this is known as Fiber Reinforced Plastics, or FRP for short. Like straw, the fiber provides the structure and strength to the composite, while a plastic polymer holds the fiber together. Common types of fibers used in FRP composites are: Fiberglass Carbon Fiber Aramid Fiber
