Preparation and application of calcined petroleum coke as friction material

I. Preparation method

The preparation of calcined petroleum coke friction materials mainly includes the following steps: 

First, select the appropriate carbon source and additives, and mix them evenly. 

Then, the calcination process is carried out at high temperature, so that the carbon source and additives form a certain crystal structure and physical phase composition. 

Finally, the calcined coke material is processed by grinding, pressing and sintering to form calcined coke friction material.

II. Application field

Calcined coke friction materials have high thermal stability and wear performance, and are suitable for high temperature, high pressure, high speed friction and wear 

environment. 

Therefore, it has a wide range of application prospects in aviation, aerospace, automobile manufacturing and other fields.

In the field of aerospace, calcined coke friction materials can be used to manufacture friction materials under high temperature, such as brake pads and clutch plates. 

Calcined coke materials not only have high stability and wear performance, but also light weight and stable friction coefficient, which can effectively improve the performance 

and safety of aircraft.

In the field of automobile manufacturing, calcined coke friction materials can be used to manufacture friction materials, clutch plates, brake pads and so on. 

Calcined coke materials have high thermal stability and wear performance, which can meet the requirements of automobile use under extreme conditions such as high speed 

driving and emergency braking.

III. Conclusion

Calcined coke friction material is a new type of material with a wide range of prospects for application, which has a simple preparation method, low cost, and high thermal 

stability and wear performance. 

It has a wide range of application prospects in aviation, aerospace, automobile manufacturing and other fields.
