Carbon Fiber

Carbon fiber is a lightweight, ultra-strong, and durable advanced material made of tightly bonded carbon atom strands. Compared to traditional materials like steel and aluminum alloys, carbon fiber offers significantly higher strength and stiffness at a much lower weight. This makes it ideal for high-performance applications requiring strength without added mass. It also offers excellent resistance to corrosion and wear, enabling long-term use in harsh environments. Its thermal and electrical conductivity further broadens its application in specialized fields. Over 90% of carbon fiber is produced from polyacrylonitrile (PAN) precursors. Manufacturing involves two key steps: stabilization and carbonization. PAN fibers are first stabilized at 200–300°C to improve their carbon yield and strength, then carbonized at around 1,500°C in an inert atmosphere to remove non-carbon elements and produce high-purity carbon fiber. While carbon fiber production demands precise control to ensure quality and performance, the process is also energy-intensive and associated with high carbon emissions.

 

Carbon Fiber Composites

Composites are materials made by combining substances with different physical or chemical properties to enhance overall performance. Carbon fiber composites consist of carbon fibers embedded in a resin matrix. In this structure, the resin provides form and bonding, while the carbon fibers bear mechanical loads and improve stiffness, fatigue resistance, and crack prevention. Due to their exceptional strength-to-weight ratio and design flexibility, carbon fiber composites are widely used in aerospace, automotive, and sports equipment industries—and are increasingly adopted in architecture, renewable energy, and consumer goods.
 

Challenges in Sustainability

Despite their advantages, carbon fiber materials pose sustainability challenges. They are difficult to recycle, often ending up in landfills or incinerators—both environmentally harmful. The manufacturing process also consumes large amounts of energy and emits considerable CO₂, making carbon fiber a resource-intensive material. Improving recyclability and reducing emissions are essential to ensuring a sustainable future for the carbon fiber industry.
 

Thermolysis Co., Ltd.: Leading in Carbon Fiber Regeneration

Currently, carbon fiber recycling methods focus on separating fibers from resin using chemical or thermal processes. However, commercial-scale recycling remains limited. At Thermolysis Co., Ltd., we use patented high-temperature pyrolysis technology to efficiently recover high-quality carbon fibers from composite waste. By investing in advanced equipment and infrastructure, we enable scalable production of recycled carbon fiber. Our process transforms discarded composites into valuable, low-carbon materials—supporting both industrial performance and environmental responsibility.
