Key Advantages
- Ultra-High Thermal Stability
Carbon fibers and ceramic additives ensure minimal brake fade even at extreme temperatures (up to 850°C), making them ideal for mountainous or high-load scenarios . - Lightweight Design
The brake linings mixture reduces overall braking system weight by 20-30%, improving fuel efficiency without compromising safety . - Low Wear and Longevity
Reinforced carbon structures and optimized brake linings formula result in a wear rate 40% lower than traditional metallic linings . - Noise and Vibration Reduction
Ceramic particles in the brake linings friction materials dampen vibrations, reducing squeal during braking. - Eco-Friendly Composition
Free from asbestos and heavy metals, aligning with global environmental regulations .
Storage and Packaging
- Moisture Protection: Packaged in sealed, vacuum-sealed bags with desiccants to prevent fiber oxidation .
- Temperature Limits: Store in environments between -20°C and 40°C to maintain material integrity.
- Stacking Guidelines: Maximum 8 layers per pallet to avoid deformation.
- Shelf Life: 18 months in unopened, original packaging.
Application of Brake Linings Mixes
The brake linings mixes are molded under high pressure (20-35 MPa) and cured at controlled temperatures to ensure adhesion between the friction layer and backing plate. Post-production tests include thermal shock cycling (500 cycles at 800°C) and shear strength validation (≥3.5 MPa) .
For specialized applications, manufacturers adjust the brake linings formula to meet OEM requirements, such as increased ceramic content for mining vehicles or enhanced carbon fiber ratios for high-speed logistics trucks.
This carbon fiber-based innovation redefines braking efficiency, offering reliability and sustainability for commercial vehicles operating in extreme conditions.
