KICKSTARTING THE WIDESPREAD ADOPTION OF AUTOMOTIVE CARBON FIBER COMPOSITES

This report by the Rocky Mountain Institute (RMI) outlines a strategic framework to increase the adoption of carbon fiber composites in mainstream passenger vehicles to reduce vehicle weight and improve fuel efficiency. Based on a November 2012 workshop with approximately 40 experts, the report proposes a 'parts-based approach' to avoid the risks of whole-vehicle redesign while scaling the supply chain. It identifies high-value parts for near-term adoption, analyzes the business case for these components, and recommends the creation of an Innovation Hub and a coordinated effort to develop lower-cost precursors to overcome material cost barriers.

• A parts- and subassembly-focused program is proposed as a viable method to catalyze carbon fiber adoption, avoiding the risks of a whole-vehicle redesign while enabling a total transformation over time. This approach is compatible with other lightweight materials and applicable across various vehicle classes.
• Near-term opportunities for carbon fiber adoption in vehicles over the next 4–6 years include part families such as doors, rear hatches, seats, and engine cradles. Analysis indicates weight savings of 60% to 70% for these parts, with an extra cost per pound saved ranging from $2.78 to $4.76.
• Fiber cost is the primary driver of carbon fiber composite part costs, with the precursor accounting for half of the production cost. The report suggests that shifting to alternative precursors, such as polyolefin, could create an explosion in adoption rates, though this faces technical and business model challenges.
• The report identifies three critical technical gaps that require noncompetitive, industry-wide collaboration: material characterization, computational predictive modeling tools, and fiber cost reduction. Current material data is often proprietary, inconsistent, and lacks a centralized database.
• To bridge the gap between research and commercial application, the report recommends establishing an Innovation Hub. This hub would centralize material data, provide shared access to manufacturing equipment and test rigs, and coordinate research between industry, academia, and government.
• Winning strategies for carbon fiber adoption must optimize designs to maximize weight savings and minimize material use. This includes using anisotropic design to match fiber directionality to load paths and employing hybrid material approaches where cheaper materials are used outside direct load paths.
