Carbon fiber fabrics are new type of fibrous material with a carbon content of more than 95% high strength and high modulus fiber.
Lightweight: 1/4 the weight of steel, ~1.8 g/cm³ density.
High strength-to-weight ratio: 5x stronger than steel at the same weight.
Corrosion-resistant: Unlike metals, it won't rust or degrade in harsh environments.
Customizable: Available as woven fabric, unidirectional sheets, or chopped strands.
The manufacturing process involves:
Precursor production: PAN (polyacrylonitrile) or pitch fibers are spun into strands.
Oxidation: Heated to 200–300°C in air to stabilize the fibers.
Carbonization: Heated to 1,000–3,000°C in inert gas to remove non-carbon atoms.
Surface treatment: Fibers are coated to improve resin adhesion.
Composite formation: Fibers are layered with resin and cured under heat/pressure (e.g., autoclave molding).
