Carbon Ceramic Brake Disks

Semicorex Carbon Ceramic Brake Disks represent the ultimate fusion of advanced materials engineering and precision manufacturing, designed to deliver unparalleled braking performance, durability, and efficiency. With carbon ceramic composite construction, the brake disk consists of carbon fibers{which} will maintain their light weight strength while also the exceptional hardness and thermal resistance of silicon carbide ceramics. The result is a unique composite structure sophisticat

edly designed for stiffness, strength, and heat dissipation that allows the brake disk to function uniformly in extreme situations when steel and cast-iron brakes would fabricate them unusable.

New energy vehicles are accelerating at a rapid pace and becoming heavier, placing stricter demands on lightweighting and braking safety. As the vehicle for safety and driving quality, the braking system has become a key area of competitive differentiation.

Mainstream gray cast iron brake discs can be brought to market at a lower price point, however, their downsides of high density and thermal fade limit their durability. Many current automotive brake discs on the market are made of gray cast iron material, which presents alternatives of light weight and price for many situations, but do experience downside such as excessive weight, thermal fade, or corrosion inhibitive, affecting endurance and energy efficiency. Continuous use in braking can lead to sustain surface temperatures that exceed 500°C, causing pearlite to disappear which in turn leads to thermal fatigue cracking of the brake disc, which also erodes friction stability for usage, and many of them are not able to meet the performance requirement of high-end electric vehicles.

Carbon Ceramic Brake Disks offer lightweight, thermal-fade resistance, and long life, making them the optimal brake actuator for intelligent driving. Carbon Ceramic Brake Disks are a multiphase composite material with carbon fiber reinforcement and a silicon carbide ceramic matrix. Its carbon fiber skeleton weighs less than one-quarter of steel and boasts a tensile strength 7-9 times that of steel. The ceramic matrix's hardness is second only to diamond and can withstand temperatures of 1650°C, eliminating the thermal degradation problem associated with traditional materials during high-speed, high-frequency braking. Its service life is expected to reach 50-100 kilometers. It offers zero-delay maximum braking force, meeting the millisecond-level response requirements of brake-by-wire without the need for an additional brake assist system. This instantaneous braking response provides the foundation for precise control in autonomous driving systems.

The significant advantage of unsprung weight reduction is that it increases the range of new energy vehicles by 25km. According to industry research, every 1kg reduction below the suspension system is equivalent to a 5-fold reduction above the suspension system. A pair of 380mm carbon-ceramic brake discs weighs 12kg, while a pair of 380mm gray cast iron discs weighs approximately 32kg, resulting in an equivalent weight reduction of approximately 100kg and a 25km increase in range. When a fuel vehicle loses 100kg in weight, fuel consumption decreases by 0.3-0.6L per 100km, fuel efficiency increases by 6-8%, and braking distance is reduced by more than 2 meters.
