The approach is scalable and cost-effective, addressing the vulnerability of composites to strain damage. These innovations in carbon fiber have paved the way for smart carbon fiber composites that offer improved mechanical performance and durability.

Cost and Efficiency Gains

Cost reduction remains a central focus in the carbon fiber market, especially for automotive applications. Partnerships between aerospace and automotive sectors, such as Boeing and ELG Carbon Fibre, have enabled the recycling of excess aerospace-grade carbon fiber. The process removes resin from cured composites, producing clean carbon fiber suitable for automotive use. This trend reduces costs by repurposing high-value aerospace carbon fiber for mass-market vehicles.

Automotive companies like General Motors collaborate with composite manufacturers to produce low-cost carbon fiber reinforced thermoplastics at scale. The high cost of carbon fiber, driven by expensive precursors and complex processes, has historically limited widespread adoption. However, ongoing development of lower-cost fibers and improved manufacturing technologies is changing the landscape. Large tow fibers and efficient production methods help reduce costs, while increasing global CO2 emission standards and carbon neutrality goals drive demand for lightweight composites.

Thermoplastic-based composites have revolutionized production efficiency. These materials are recyclable, supporting circular economy goals and meeting regulatory requirements such as the EU End-of-Life Vehicle Directive. Injection molding of thermoplastic composites enables high-throughput manufacturing, producing millions of parts annually. Recycling thermoplastic composites consumes far less energy and cost compared to virgin carbon fiber production, while maintaining over 95% of the original tensile strength and stiffness. Techniques like size-exclusive sieving improve fiber length retention and material homogeneity, ensuring consistent mechanical properties in recycled composites.

The carbon fiber market continues to expand rapidly. The global CFRP market reached USD 18.92 billion in 2024, with the automotive segment exhibiting a forecasted CAGR of 9.1%. Lightweight applications, aluminum replacement, and the demand for fuel-efficient vehicles drive this growth.

Broader Industry Use

Mainstream automotive adoption of aerospace-grade carbon fiber for automotive remains limited but shows promising trends. BMW stands out as the primary mainstream brand to incorporate this advanced material in mass-market vehicles. The BMW i3 and i8, introduced in 2013, marked a significant step forward by featuring extensive carbon fiber use. BMW’s ‘Carbon Core’ philosophy, first applied to the 7-Series platform in 2015, represents a breakthrough in integrating carbon fiber into mainstream vehicles. This approach continues with the BMW iX SUV, advancing the use of carbon fiber in mass-market production.

Note: Most other mainstream original equipment manufacturers (OEMs) have not adopted aerospace-grade carbon fiber for automotive on a large scale. Usage remains concentrated in niche, low-volume, or motorsports applications due to cost and manufacturing challenges.

Historical attempts at high-volume carbon fiber vehicles, such as the 1984 Ford Econoline driveshaft, were short-lived because of high costs. While some brands have used carbon fiber for specific components like B-pillars, widespread adoption beyond BMW has yet to occur. The automotive industry continues to explore new manufacturing methods and cost-reduction strategies to enable broader applications of aerospace-grade carbon fiber for automotive.

Performance and Safety

Aerospace-grade carbon fiber for automotive delivers significant benefits in vehicle performance and occupant protection. The material’s high strength and low weight contribute to improved acceleration, handling, and fuel efficiency, supporting the ongoing trend of automotive lightweighting. In high-performance applications, carbon fiber structures enable designers to create complex aerodynamic shapes that optimize energy use and stability.

Crash safety remains a critical consideration in automotive applications. Finite element simulations using tools like Ansys LS-Dyna have evaluated the crashworthiness of carbon fiber reinforced plastic (CFRP) chassis. These studies show that carbon fiber structures can absorb significant impact energy, maintaining occupant protection within acceptable limits under certain crash scenarios. For example, a lightweight solar vehicle chassis made from CFRP demonstrated effective energy absorption and head injury protection at moderate overlap impacts. However, tests also revealed that seatbelt forces could exceed safe limits without proper load limiters, emphasizing the need for careful structural design.

Modifications to carbon fiber sandwich structures, such as adding corrugated layers in the front crash box, help maintain energy absorption capacity. These findings highlight that aerospace-grade carbon fiber for automotive can provide robust crash safety, but engineers must optimize layup and structural features to ensure occupant protection. As adoption increases, automotive manufacturers continue to refine these designs, balancing lightweight construction with stringent safety requirements.

Automotive applications of aerospace-grade carbon fiber continue to expand, driven by the pursuit of lighter, stronger, and safer vehicles. The industry’s focus on innovation and cost reduction will shape future trends, enabling broader use of carbon fiber in both high-performance and mainstream vehicles.
