[Material revolution under fatigue and anxiety]

In the uncertain year of 2026, every liter of fuel consumption affects the nerves of car owners. For automotive engineers and experienced car enthusiasts, traditional means of reducing braking often focus on improving thermal efficiency and drag coefficient. However, an "energy efficiency black hole" that is often overlooked is hidden in wheel hub consumption—— mass under spring .

Industry recognized: "1kg below spring, 10kg above spring" Although traditional cast iron brake discs are expensive, their heavy body not only increases the inertial load of the transmission system, but also consumes excess consumption by turning off the brakes. In this context, carbon ceramic composites With its extreme lightweight and thermal stability, it is becoming the "vanguard" of weight reduction and consumption reduction in the automobile industry from the high-end civilian market.

【Performance cutting edge of precision ceramics】

The application of precision ceramics in braking systems is mainly based on carbon fiber reinforced silicon carbide. This is not an ordinary "mud ceramic", but a structural composite ceramic material manufactured through precision processes.

1. Silicon carbide: the cornerstone of carbonization and wear resistance

Silicon carbide ceramics have extremely high height (Mohs hardness above 9) and excellent thermal conductivity. During the braking process, the instantaneous temperature generated by the brake pads and discs reaches more than 1,000 degrees Celsius. Ordinary steel discs will heat up or even deform at this temperature, while the silicon carbide matrix can maintain extremely high physical stability.

2. Carbon fiber reinforcement: the secret to endurance and weight loss

By introducing carbon fiber into the ceramic matrix, the shortcoming of "brittleness" of traditional ceramics is completely overcome.

Maximum light weight : The density pattern of carbon ceramic discs is about 2.4g/cm3, which is about the same as that of traditional cast iron discs (7.2g/cm3) 1/3 A complete carbon ceramic braking system can reduce the weight of the entire vehicle More than 20kg .

High heat capacity : Its specific heat capacity is much higher than that of metal, which means it can absorb more heat under the same mass, and the braking distance is about 15%-25% .

[From extreme working conditions to daily fuel saving]

1. Reducing the “consumption economy” brought about by agility

For procurement and equipment engineers, the value of carbon ceramic brake pads lies not only in "stopping" but also in "running less".

Due to the reduction in the amount of rotational inertia of the wheel hub, the data collected when the vehicle starts is significantly reduced. Experimental data shows that the weight under the spring is reduced by 20kg, and under urban congestion conditions (start-stop is turned off), the vehicle can be improved by approximately 2%-3% fuel efficiency. In the context of long-term high retail sales, this part of the fuel cost savings and the extension of consumable replacement cycles make up for the overall cost of the carbon ceramic system.

2. Zero thermal attenuation and ultra-long life

Anti-heat decay, The coefficient of the carbon ceramic system tends to be stable at high temperatures, eliminating the softening of the braking force when going downhill on mountain roads or braking at high speeds.

Consumption is long, The wear of traditional metal discs usually ranges from 60,000 to 80,000 kilometers, while precision ceramic discs can achieve More than 300,000 kilometers The service life has almost achieved "vehicle-grade replacement-free throughout the life cycle".

3. Environmental protection and NVH optimization

Precision ceramic brake pads remove asbestos and heavy metals and have a very low friction coefficient, effectively solving the problem of traditional brake pads contaminating the wheel hub. At the same time, by precisely controlling the waveform rate and density distribution of the material, high-frequency braking squeal can be significantly suppressed.

【Precision Manufacturing Hub】

The production of high-performance carbon ceramic brake pads is a complex process. The current mainstream processes include:

1. Needle punch/knitted preform , build a carbon fiber skeleton.

2. Vapor deposition (CVI) or resin carbonization (PIP) , filling the carbon matrix in the fiber gaps.

3. Leakage of silicon methane (LSI) , this is the most critical step. In a high-temperature vacuum environment, the adsorbed silicon penetrates into the gaps and reacts with carbon. Silicon carbide ceramic matrix .

4. Precision grinding and dynamic balancing , because the material is extremely hard, diamond tools must be used for high-precision processing with micron-level precision.

[Inclusiveization and technology sinking]

Currently, carbon ceramic systems are mostly standard equipment in supercars and high-performance SUVs, but with the Domestic precision ceramics industry chain of maturity, costs are positive each year 10% - 15% the downward speed.

Integrated design , in the future ceramic brake pads will be deeply integrated with brake-by-wire (Brake-by-Wire).

Ceramic hybrid solutions , targeting mid-range ceramics, developing ceramic-coated discs or semi-ceramic materials to balance performance and cost.

[Choose ceramics, choose the future]

Today, as the automotive industry is accelerating towards performance and low-carbonization, precision ceramics are no longer expensive playthings in the laboratory, but the key to solving the pain points of weight reduction, safety and energy efficiency.
