High-performance aircraft brake-disc production and sales, long dominated by foreign firms, are seeing a domestic breakthrough as Chinese materials technology advances. Chinese developers have independently produced carbon-ceramic brake materials that offer improved moisture resistance, higher temperature tolerance and more stable braking across the full temperature range, marking a step-change in key brake-material technology. Industry sources say application of domestically produced high-performance brake materials is expanding into emerging aviation segments, and the full supply chain — from carbon-based composite material R&D and brake-disc fabrication to anti-skid electronically controlled brake systems — is now localized and in mass production.
