What is carbon fiber
What is carbon fiber
Carbon fibers, also spelled carbon fibres, are thin filaments made primarily of carbon atoms. Each fiber measures about 5–10 micrometers in diameter, with atoms bonded together in aligned crystalline structures. These crystalline filaments give carbon fibers (CF) their exceptional stiffness, tensile strength, and high strength-to-weight ratio.
This process involves oxidation, carbonization at high temperature in an inert atmosphere, and fiber weaving to create uniform strands. Advanced steps like prepregging, curing, and precision machining ensure quality parameters and structural transformation. Thousands of these filaments are bundled into tow and woven into fabric. When combined with resin, the fabric forms composite materials such as carbon-fiber-reinforced polymer (CFRP) or reinforced carbon-carbon composites.
Key properties of carbon fibers include lightweight performance, chemical resistance, temperature tolerance, and low thermal expansion. These characteristics make carbon fibers suitable for demanding environments in aerospace, civil engineering, military equipment, and motorsports.
Carbon fibers remain expensive compared to alternatives such as glass fiber, basalt fibers, or plastic fibers, but their superior properties secure their role in high-performance design.
