Advantages of Ceramic Fiber in Brake Pads Formula
- Superior Thermal Resistance: Withstands extreme temperatures (up to 1260°C), reducing brake fade and ensuring stable performance in high-stress conditions.
- Low Thermal Conductivity: Minimizes heat transfer to brake components, preventing rotor warping and extending system lifespan.
- Noise and Vibration Reduction: Acts as a damping agent in the brake pads mixture, reducing squeal and improving driver comfort.
- Lightweight Design: Low density (0.1–0.3 g/cm³) contributes to weight reduction, enhancing fuel efficiency.
- Eco-Friendly Composition: Asbestos-free and non-corrosive, aligning with global environmental regulations.
Storage and Packaging Guidelines
To maintain the integrity of brake pads mixes containing ceramic fiber:
- Packaging: Sealed woven polyethylene bags (25 kg/bag) with moisture-resistant liners and desiccants.
- Storage Conditions:
- Temperature: 10°C–30°C (avoid thermal cycling).
- Humidity: <60% RH.
- Protect from UV exposure and chemical contaminants.
- Shelf Life: 12–18 months in unopened packaging.
Key Applications in Brake Pads Ingredients
Ceramic fiber is blended into brake pads formula with:
- Reinforcement Materials: Aramid fibers, steel fibers.
- Binders: Phenolic resins or rubber-based adhesives.
- Fillers: Graphite, barium sulfate, and cashew dust.
This combination optimizes friction stability (μ = 0.35–0.45), wear resistance, and compliance with automotive standards like SAE J661.
Conclusion
Ceramic fiber is indispensable in modern brake pads friction materials, offering unmatched thermal resilience, noise reduction, and environmental safety. Its integration into brake pads mixes exemplifies innovation in automotive engineering, delivering reliability for high-performance braking systems.
