High-End Composites: Why Is Carbon Fiber So Expensive?

The first commercial carbon fiber was created by Thomas Edison for use in the first incandescent light bulb in 1879.

However, the exceptional properties of carbon fiber come at a cost, making it one of the most expensive materials in the world. This article explores the intricacies of this high-end composite material, shedding light on why is carbon fiber so expensive.

Additionally, the production of carbon fiber involves energy-intensive steps, such as the carbonization process. The need for specialized equipment and controlled environments throughout the production process adds to the overall expense.

The precursor materials used in the production of carbon fiber, particularly high-quality PAN, contribute significantly to the material's overall cost. PAN-based carbon fibers are known for their superior strength and performance, but the precursor material itself is expensive to produce.

The selection of high-grade raw materials is crucial to ensure the resulting carbon fiber meets the stringent requirements of industries like aerospace and automotive.

Furthermore, the manufacturing process may lead to waste and by-products, adding to the overall production costs. The meticulous control required to produce high-quality carbon fiber contributes to a lower yield, further impacting the cost of the final product.

Research and development efforts are ongoing to enhance the efficiency of the production process, reduce waste, and discover alternative precursor materials that may offer cost-effective solutions. However, the initial investment in these advancements can increase the overall cost of carbon fiber until economies of scale are achieved.
