D773 Brake Pads

Development of brake pads

Friction materials have been around for more than 100 years since their inception. The development of its raw materials, from the initial direct application of mineral raw materials to today's pursuit of synthesis and finishing materials; from asbestos and other harmful materials to the current green materials; from a small number of previous materials to a large number of materials today to compound Even a functional requirement is no longer implemented in a single material.

From the current technical development of brake pads worldwide, the most successful research and application of semi-metal formulations should be in North America; the most successful research and application of less metal formulations should be in Europe; the research and application of NAO formulations The most successful one should belong to Japan. Although various formulations have a market for their applications, major manufacturers are currently focusing on the development of ceramic formulations and carbon fiber formulations. The development of the automotive brake industry is also tending to environmental protection, low carbon and other fields.

Advantages of automotive ceramic brake pads

The current trend of automotive brake pads is carbon fiber and ceramics. The biggest difference between ceramic brake pads and less metal brake pads is the metal material. Among the metal brake pads, the metal is a material that mainly generates friction, and the braking force is large, but the wear is large, and noise is prone to occur. The ceramic brake pads do not contain metal components, so the metal squeaks caused by the friction between the metal brake pads and the counterparts are avoided.

Ceramic brake pads also have the advantage of a more stable coefficient of friction. The coefficient of friction is an important indicator of any friction material. It is related to the braking ability of the brake pads. During the braking process, heat is generated due to friction, and the temperature rises. Generally, the friction material of the brake pad is affected by the temperature, and the friction coefficient begins to decrease. In practical applications, the friction is reduced, which reduces the braking force. However, the friction coefficient should not be too high, and the excessively high friction coefficient may cause unsafe factors such as out of control, burning, scratching the brake disc during braking. The ceramic formula can ensure the braking performance of the vehicle under high temperature conditions and ensure the safety of the vehicle.

Ceramic brake pad material

Nowadays, the ceramic formula brake pads of automobiles are widely used in the market, and their performance is greatly improved compared with the original products. The ceramic formula contains ceramic materials. Ceramic materials are currently used in many places, and their advantages are quite outstanding.

Ceramic materials have good thermal stability and low thermal conductivity, and good wear resistance. The long-term use temperature is 1000 °C. This feature makes ceramics suitable for high performance requirements of various high performance brake materials, and can meet the technical requirements of high speed, safety and high wear resistance of brake pads. It also has a very low thermal attenuation, ensuring that the vehicle has good braking performance to ensure safety, and the thermal attenuation of the brake pads is small to improve the performance of the brake pads. Due to the fast heat dissipation of the ceramic material, the friction coefficient of the brake pad is higher than that of the metal brake pad.
