PV Composite Steel Hat Brake Discs

Brake Discs Features

1. Hybrid Construction:

• Composite Friction Ring: Constructed from PV composite (phenolic resin + reinforcing fibers) for low weight, high heat resistance, and reduced wear.

• Steel/Aluminum Hat: Lightweight hub for structural support, reducing unsprung weight and improving handling.

2. Thermal Performance:

• Optimized ventilation channels and composite material design dissipate heat efficiently, minimizing brake fade during heavy use (e.g., highway braking or track sessions).

3. Durability & Corrosion Resistance:

• Composite material resists rust and corrosion from road salt/moisture, extending service life compared to cast iron discs.

4. OE Compatibility:

• Direct fitment for select vehicle models without modifications, ensuring seamless integration with ABS, ESC, and regenerative braking systems (for EVs).

5. Noise & Dust Reduction:

• Composite friction surface reduces brake noise and dust generation, enhancing cabin comfort and environmental friendliness.

Brake Discs Benefits

1. Weight Reduction:

• Up to 15% lighter than full cast-iron discs, improving acceleration, fuel efficiency, and suspension responsiveness.

2. Enhanced Safety:

• ECE R90 certification guarantees compliance with braking performance and structural safety standards.

3. Cost Efficiency:

• Longer lifespan and reduced maintenance (e.g., fewer replacements due to corrosion/wear) lower total ownership costs.

4. EV-Specific Advantages:

• Lightweight design aligns with EVs’ energy-saving goals, while heat resistance complements regenerative braking systems.

5. Performance Consistency:

• Stable friction coefficient across wide temperature ranges ensures predictable braking feel in both daily driving and extreme conditions.

• 100% critical dimensions, runout and DTV inspection 

• Material physical and chemical inspection

• Test shear strength, compressibility, density, flatness and parallelism 

• Test performance and noise/NVH
