Fiberglass is a lightweight and corrosion-resistant plastic resin that contains glass for added strength. Carbon fiber is a lightweight and corrosion-resistant composite material that's stronger but less flexible than fiberglass and contains carbon fibers for strength and rigidity. Structural fiberglass reinforced plastics come in different shapes and are lightweight, nonconductive, and have a good strength-to-weight ratio. Electrically insulating fiberglass epoxy laminates have properties that protect against arc flash, static, and electrical charge. High-strength carbon fiber reinforced plastics are durable, stiff, and come in different shapes for specific applications.
