Introduction to Truck Brake Linings Ceramic-Based Mixture
Truck brake linings ceramic-based mixtures are high-performance brake linings friction materials designed for heavy-duty applications, combining ceramic matrices with reinforcing fibers and binders. This advanced brake linings formula ensures superior thermal stability, minimal wear, and eco-friendly operation, making it ideal for modern commercial vehicles operating under extreme conditions.
Technical Parameters
The table below outlines key specifications of ceramic-based brake linings mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Ceramic Content | 40-60% (Silica, Alumina, Zirconia) | Enhances heat resistance |
| Density | 2.4-2.8 g/cm³ | Lightweight yet durable |
| Friction Coefficient (μ) | 0.30-0.40 (Dry) | Consistent across 0°C–800°C |
| Operating Temperature | -50°C to 850°C | Resists thermal degradation |
| Wear Rate | ≤0.3 cm³/MJ | Extended service life |
| Shore Hardness | 55-70 Shore D | Optimized for drum/pad compatibility |
| Compressive Strength | ≥250 MPa | Withstands high-pressure braking |
Key Advantages
- Exceptional Heat Resistance
Ceramic components like alumina and silica provide unmatched thermal stability, reducing brake fade even at 850°C . - Low Noise and Vibration
The brake linings mixture incorporates ceramic particles to dampen vibrations, minimizing squeal during braking. - Environmentally Friendly
Asbestos-free composition aligns with global safety standards, reducing hazardous dust emissions . - Lightweight Design
Lower density (2.4-2.8 g/cm³) reduces unsprung weight, improving fuel efficiency. - Corrosion Resistance
Ceramic matrices prevent oxidation, ensuring longevity in humid or saline environments.
Storage and Packaging Guidelines
- Moisture Protection: Store in vacuum-sealed, moisture-proof packaging to prevent ceramic component degradation.
- Temperature Limits: Avoid exposure to temperatures exceeding 50°C or below -20°C.
- Stacking: Limit to 4 layers to prevent cracking under pressure.
- Shelf Life: 18 months in unopened, UV-resistant packaging.
Application of Brake Linings Mixes
The brake linings formula is molded under high pressure (20-35 MPa) and sintered to achieve optimal adhesion between the friction layer and backing plate . Post-production testing includes thermal cycling (500 cycles at 800°C) and shear strength validation (≥3.5 MPa). Customizable formulations are available for OEMs requiring specific wear rates or noise profiles .
This ceramic-based innovation delivers reliable, low-maintenance braking solutions for trucks navigating demanding terrains or high-load scenarios.
