- Wear Resistance: Given the abrasive nature of cement clinker, wear resistance is crucial to prolong the lifespan of brake components.
- Friction Coefficient: An optimal friction coefficient ensures effective braking performance, even at high operating temperatures.
- Moisture Resistance: The ability to perform reliably in varying environmental conditions is necessary to avoid performance loss.
Material Composition
The composition of high-temperature friction materials typically includes various organic and inorganic compounds. Commonly used ingredients may consist of:
- Phenolic Resins: These resins provide excellent binding properties, thermal stability, and resistance to moisture.
- Fibers: Reinforcing fibers such as aramid or glass enhance the mechanical properties and strength of friction materials.
- Filler Materials: Fillers like barium sulfate or calcium carbonate are added to improve thermal conductivity and reduce wear.
- Metallic Components: Incorporating metals such as copper or brass can enhance heat dissipation and increase the overall efficacy of the material.
Performance Testing Standards
To ensure the reliability of high-temperature friction materials, rigorous testing under standardized conditions is essential. Common tests include:
- Friction Testing: Assessing the frictional performance across a range of temperatures and pressures, simulating real-world operating conditions.
- Wear Testing: Measuring material loss over time to determine longevity and durability in high-stress scenarios.
- Thermal Cycling Tests: Evaluating the material's ability to withstand sudden temperature fluctuations without failure.
