What is Carbon Fiber?

Carbon fiber consists of thin strands of carbon atoms. These fibers are incredibly strong and lightweight. When woven into fabric, they create carbon fiber fabric, which adds extra utility. This combination of strength and lightness makes it ideal for a variety of uses.

The Components of Carbon Fiber Raw Materials

The primary raw materials for carbon fiber include polyacrylonitrile (PAN), pitch, and rayon. Each material contributes differently to the final product.

1. Polyacrylonitrile (PAN)

PAN is the most widely used precursor for making carbon fibers. About 90% of carbon fibers are derived from PAN. The process begins with creating a fiber from PAN, which is then heated. This heating removes the non-carbon elements, leaving thin strands of pure carbon.

2. Pitch

Pitch is derived from petroleum and coal. It’s less commonly used than PAN but offers unique benefits. Carbon fibers made from pitch possess higher elasticity and thermal conductivity. These properties make them suitable for specific applications, such as high-performance industrial products.

3. Rayon

Rayon is another precursor used in creating carbon fibers. While it’s not as popular as PAN or pitch, it’s still noteworthy. Rayon-based fibers are generally softer and can be beneficial for textiles. This can lead to a different texture and feel in the final carbon fiber fabric.

The Process of Making Carbon Fiber

Creating carbon fiber involves several steps.

1. Spinning: The chosen precursor is spun into fibers.
2. Stabilization: This step includes heating the fibers to prepare them for carbonization.
3. Carbonization: In a zero-oxygen environment, fibers are heated to temperatures over 1000°C. This removes non-carbon atoms.
4. Surface Treatment: After carbonization, fibers are treated to improve bonding with other materials.
5. Sizing: Finally, fibers are coated with a protective layer to enhance performance.

Applications of Carbon Fiber

Carbon fiber and its raw materials have found applications in various fields.
