KBC Brings Carbon-Ceramic Brake Technology to Xiaomi CEC Racing

Updated on September 01, 2026 • 5 min read

Chinese advanced composites manufacturer KBC Corp. Ltd. has been named an official partner of the 2026 Xiaomi China Endurance Championship (CEC), bringing its long carbon fiber-reinforced carbon-ceramic brake technology from high-performance road vehicles into professional endurance racing.

Under the partnership, KBC Corp. will provide a dedicated carbon-ceramic braking package for CEC race cars while working with the championship on technical development and race support.

The program gives KBC another operating environment in which to evaluate its carbon-ceramic materials under sustained high temperatures and repeated braking cycles — conditions particularly relevant to endurance competition.

Carbon-Ceramic Brakes Target Endurance Racing Heat Loads

Braking systems used in endurance racing experience a different duty cycle from those in conventional road vehicles.

Repeated high-energy braking events generate substantial heat, while long race durations leave limited opportunity for the brake system to return to lower operating temperatures.

As temperatures accumulate, maintaining stable friction behavior and limiting thermal fade become important performance considerations.

KBC says its race-specific carbon-ceramic brake system has been engineered for these conditions and can withstand more than 400 minutes of continuous operation under extreme racing conditions while maintaining stable braking performance.

The company is positioning high-temperature resistance and reduced thermal fade as key attributes of the system.

Detailed test conditions behind the 400-minute figure, including braking loads, operating temperatures and test methodology, were not disclosed in the supplied announcement, so direct comparisons with other racing brake systems cannot yet be made.

Long Carbon Fiber Reinforces Ceramic Brake Discs

The CEC program builds on KBC’s development of long carbon fiber-reinforced carbon-ceramic brake discs.

Carbon-ceramic braking materials combine carbon fiber reinforcement with a ceramic-containing matrix system to provide a combination of thermal capability, wear performance and reduced mass suitable for demanding vehicle applications.

Compared with conventional metallic brake discs, carbon-ceramic systems can offer weight-saving potential, reducing rotating and unsprung mass.

For performance vehicles, however, their attraction extends beyond lightweighting.

Brake discs must maintain structural and frictional performance while repeatedly absorbing and dissipating substantial quantities of thermal energy. Carbon-ceramic materials are therefore particularly relevant where high operating temperatures and repeated severe braking are expected.

The exact material composition and manufacturing route used for KBC’s CEC brake discs have not been disclosed.

Technology Already Used in Chinese Performance Vehicles

The racing partnership represents another stage in the commercialization of KBC’s braking technology rather than its first automotive deployment.

The company has supplied carbon-ceramic brake components for several high-performance production vehicles in China.

Applications cited by KBC include the Hyper SSR, models from BYD’s Yangwang brand and the Xiaomi SU7 Ultra.

Moving from high-performance production cars into endurance racing gives the material system a substantially different operating profile.

A road-going performance vehicle may experience occasional severe braking events. An endurance race car can repeat high-energy braking cycles for hours, creating sustained thermal and mechanical loading on the discs and the complete braking system.

Motorsport Creates a Development Environment for Composite Brakes

For KBC, participation in the CEC provides more than product exposure.

Motorsport can provide a concentrated development environment where brake temperature, wear, consistency and component behavior can be evaluated under repeated severe loading.

This could generate useful information for subsequent development of road-going carbon-ceramic brake systems.

However, performance in racing does not automatically translate directly to production vehicles.

Road-car brake systems face their own requirements involving cold braking behavior, noise and vibration, durability, environmental exposure, cost and long-term serviceability.

The value of the CEC program will therefore depend partly on how KBC translates lessons from racing into materials and manufacturing improvements for future production applications.

Professor’s Analysis: Carbon-Ceramic Brakes Are Becoming a Manufacturing Story

Carbon-ceramic brake discs are interesting from a composites perspective because their value proposition combines thermal performance with lightweighting, rather than focusing on structural mass reduction alone.

But the larger industrial question is increasingly manufacturing.

Producing a brake disc that performs under extreme conditions is one challenge. Producing those discs consistently, at automotive quality levels and at a cost that enables broader vehicle adoption is another.

This distinction matters as China’s high-performance vehicle market expands.

The presence of KBC’s technology on vehicles such as the Xiaomi SU7 Ultra and BYD Yangwang models suggests that domestic carbon-ceramic brake technology is moving beyond laboratory development toward serial automotive applications.

Endurance racing adds another validation environment.

If a brake system is subjected to hundreds of minutes of repeated thermal cycling, engineers can study not only peak-temperature capability but also how performance evolves with time, wear and repeated loading.

For composite material developers, this is particularly valuable because damage and degradation can accumulate at several levels — reinforcement, matrix, interfaces and the finished friction surface.

There is nevertheless an important technical distinction to maintain.

Carbon-ceramic brakes should not be confused with carbon-carbon brakes.

Both use carbon fiber and are associated with high-temperature braking applications, but their matrix systems, manufacturing routes, operating characteristics and typical applications differ.

That distinction becomes increasingly important as advanced friction materials move across aerospace, motorsport and high-performance automotive markets.

Racing Program Supports Broader Automotive Ambitions

KBC says it will continue developing carbon-ceramic materials and associated manufacturing technologies, with broader high-performance automotive adoption among its objectives.

Its 2026 Xiaomi CEC partnership provides a demanding platform for that work.

The most useful results may ultimately come from what happens after the racing season: whether endurance data can be converted into improvements in material formulation, manufacturing consistency, service life or cost for production brake systems.

For China’s expanding carbon-ceramic brake industry, the CEC program provides another indication that the technology is moving from specialized materials development toward a more mature automotive manufacturing ecosystem.
