Key Advantages
- Enhanced Durability
- The Brake Pads Mixes of silicon carbide (15–20%) and copper fibers (10–15%) reduce wear rates by 40% compared to traditional semi-metallic pads.
- Service life: 80,000–100,000 km under full-load truck conditions.
- Superior Heat Management
- Maintains stable friction coefficient (μ >0.35) even at 700°C, preventing brake fade during prolonged downhill braking.
- Noise & Vibration Reduction
- Sintered ceramic brake pads friction materials dampen high-frequency noise (<75 dB) through optimized pore structure design.
- Corrosion Resistance
- Non-hygroscopic formula minimizes moisture absorption (<0.3%), preventing rotor rust in humid environments.
Storage & Packaging Specifications
- Packaging:
- Individually wrapped in anti-oxidation vacuum bags with desiccant.
- Reinforced cartons with “Fragile” and “Keep Dry” labels.
- Storage:
- Temperature: -10°C–35°C (avoid direct sunlight).
- Maximum stacking height: 8 layers.
- Shelf life: 24 months in original packaging.
Formula Composition
The brake pads formula comprises three core layers:
- Friction Layer
- Ceramic matrix: 50–60% (silicon carbide + alumina)
- Metallic reinforcements: 20–25% (copper fibers, iron powder)
- Intermediate Layer
- Bonding agents: 12–15% (modified phenolic resin)
- Backing Plate Interface
- Adhesive: High-temperature epoxy (shear strength ≥18 MPa).
This sintered brake pads mixture undergoes 1,050°C hot-pressing and 8-hour annealing, achieving 98% densification for optimal load-bearing capacity.
