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
