Carbon Fiber Testing

Carbon fiber is an inorganic fibrous material with a carbon content exceeding 90%. It is characterized by high strength and high modulus, light weight, high temperature resistance, corrosion resistance, and electrical and thermal conductivity. China's carbon fiber industry rose to prominence in the 2020s. By 2025, China's share of global production capacity reached 47.7%, with the localization rate of T800-grade products exceeding 85%. The global market size for carbon fiber grew from US$15 billion in 2020 to US$20 billion in 2025, with a CAGR exceeding 10%. Leveraging cost advantages (30% lower prices) and capacity expansion, China's export volume increased by 40% year-on-year in 2025. China's "New Materials Industry Development Plan" explicitly aims for self-sufficiency in high-end products by 2030, and the Civil Aviation Administration of China (CAAC) requires that carbon fiber account for over 70% of eVTOL airframe structures.
