In various friction material formula, synthetic graphite(also call artificial graphite) is a crucial component. What specific roles does it play in friction materials? 

Today, we will list its specific functions:

1. Improving Wear Resistance:
        High hardness and wear resistance enable synthetic graphite to form a protective layer during friction, preventing surface wear and abrasion. This enhances friction material durability.

2. Reducing Friction Coefficient:
        Its interlayer structure provides low intermolecular forces, granting self-lubrication. During friction, it forms a lubricating layer, reducing direct contact and friction, thereby lowering the friction coefficient.      This minimizes heat and energy loss, improving efficiency.

3. Enhancing Thermal Stability:
        High thermal conductivity and oxidation resistance improve friction material's thermal stability. Artificial graphite quickly dissipates heat, preventing material failure due to overheating, which is crucial for thermal fade resistance.

4. Reinforcing Material Properties:
        Chemical stability protects against chemical effects, enhancing corrosion resistance. Its electrical and thermal conductivity improve heat and electricity transfer, further boosting overall material performance and lifespan.

5. Reducing Brake Noise:
        Lubricating properties not only lower the friction coefficient but also reduce brake noise. This makes synthetic graphite ideal for brake materials like automotive brake pads and motorcycle clutches.

In summary, synthetic graphite in friction materials enhances wear resistance, reduces friction coefficient, improves thermal stability, reinforces material properties, and minimizes brake noise. These roles make it an indispensable component, enhancing friction material performance and lifespan.
