High-strength carbon fiber plastics are rigid and lightweight, resist corrosion, and contain carbon fibers that make them stronger than fiberglass. They are available in different shapes and sizes for specific applications. Carbon fiber flat bars have rectangular or square cross sections and contain unidirectional or woven carbon fibers. They’re often used for commercial, industrial, and automotive applications. Carbon fiber sheets contain unidirectional or woven carbon fibers and are commonly used for marine, automotive, and aerospace applications. Carbon fiber round tubes are hollow, rigid, and contain unidirectional or woven carbon fibers. They are often used for structural and architectural applications. Solid carbon fiber rods have round cross sections and contain unidirectional carbon fibers. They are often used for structural supports and automotive and aerospace applications.
