These unidirectional carbon fiber flat bars are made with a lightweight plastic composite material with fibers running in a single direction, which provides added strength and stiffness. They offer excellent machinability and conduct heat and electricity. Carbon fiber flat bars are resistant to corrosion and chemicals and are commonly used for industrial, marine, sport, and aerospace applications.

Woven carbon fiber flat bars are five times stronger than steel and twice as stiff. Also called graphite fiber, they are commonly manufactured into parts and components for automobiles, bicycles, and boats.
