Low-altitude economy emerges as a core growth driver, fueling explosive demand for carbon fiber. Low-altitude transportation (airspace below 1,000 meters) is transitioning from “niche operations” to “mass services,” with carbon fiber seeing large-scale adoption primarily in: * Passenger commuting scenarios: eVTOL flying cars accelerate commercialization, with composite materials constituting over 80% of the airframe; * Freight logistics scenarios: Large cargo drones leverage carbon fiber to achieve “heavy-load, long-range” capabilities. and operational service scenarios: drones for agricultural spraying and power line inspections enhance operational efficiency through carbon fiber lightweighting, with composite material usage per unit increasing from 30% to 60% and endurance extending from 2 hours to over 5 hours.
