Description

Carbon ceramic brake disc device

The present invention relates to a carbon-ceramic brake disc device, in particular to a carbon-ceramic brake disc device with a structure for improving braking performance.

Commonly known brake devices are drum brakes and disc brakes. Both of these brake devices use pads to rub the brake drum or the brake disc, and then through the increasing friction to achieve deceleration At the same time, the brake disc is connected with the support disc to achieve the purpose of decelerating or stopping the vehicle.

Generally, the brake discs commonly found on the market use stainless steel as the main component. However, the weight, heat resistance, and deformation resistance of stainless steel brake discs are poor in use. Therefore, the stainless steel is added when racing at high speed. The brake disc will increase the overall weight of the vehicle, and it is prone to deformation of the brake disc during prolonged activation.

Ceramics have the characteristics of hardness, wear resistance and electrical resistance, so they are often used in optoelectronics, semiconductors, and electrical equipment. However, because ceramic materials do not have elasticity and ductility, the use of ceramic materials to make composite materials will have a wider range of application.
