Introduction to Motorcycle Brake Shoes Carbon-Metallic Mixture
Motorcycle brake shoes carbon-metallic mixtures are high-performance brake shoes friction materials engineered to balance durability, heat resistance, and braking efficiency for demanding two-wheeled applications. This advanced brake shoes formula integrates carbon fibers with metallic reinforcements (e.g., steel, copper) and ceramic additives, achieving superior friction stability, lightweight design, and extended service life. Below is a detailed analysis of its composition, technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below outlines key properties of carbon-metallic brake shoes mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Carbon Fiber Content | 10-20% (PAN-based fibers) | Enhances heat dissipation and reduces weight |
| Metallic Content | 30-40% (Steel fibers, Copper particles) | Improves thermal conductivity and wear resistance |
| Density | 2.0-2.8 g/cm³ | Balances lightweight and structural strength |
| Friction Coefficient (μ) | 0.38-0.45 (Dry) | Stable under high-speed and wet conditions |
| Operating Temperature | -50°C to 650°C | Resists thermal fade during aggressive braking |
| Compressive Strength | ≥280 MPa | Withstands high hydraulic pressure |
| Wear Rate | ≤0.4 cm³/MJ | 30% lower than conventional metallic mixtures |
| Shear Strength | ≥3.5 MPa | Ensures bonding integrity with shoe plates |
Key Advantages
- Enhanced Heat Management
The brake shoes mixture combines carbon fibers and metallic particles to rapidly dissipate heat, minimizing brake fade during prolonged downhill rides or track use. - Lightweight and Fuel-Efficient
With a density of 2.0–2.8 g/cm³, the brake shoes friction materials reduce rotational mass by 15–20%, improving motorcycle acceleration and fuel efficiency. - High Durability
Steel fibers and ceramic additives in the brake shoes formula reduce wear rates, extending lifespan to 15,000–30,000 km under normal riding conditions. - Noise and Vibration Damping
Ceramic particles in the brake shoes mixes suppress high-frequency vibrations, eliminating squeal common in metallic-only formulations. - Environmental Compliance
Asbestos-free composition and low dust emission align with global regulations (e.g., EU REACH).
Storage and Packaging
- Moisture Control: Packaged in vacuum-sealed, anti-corrosion bags to prevent oxidation of metallic components.
- Temperature Limits: Store at 0°C–35°C; avoid extreme humidity to maintain adhesive integrity.
- Stacking: Maximum 5 layers to prevent deformation of friction layers.
- Shelf Life: 18 months in unopened, factory-sealed containers.
Application of Brake Shoes Mixes
The brake shoes mixes are precision-molded under high pressure (18–25 MPa) and cured to bond the carbon-metallic matrix to aluminum or steel backing plates. Post-production testing includes thermal cycling (500 cycles at 650°C) and shear strength validation (≥3.5 MPa) to ensure reliability in urban and off-road environments. Custom formulations are available for OEMs seeking tailored friction profiles or compatibility with ABS systems.
By synergizing carbon’s lightweight properties with metallic robustness, this brake shoes friction material delivers unmatched performance for motorcycles requiring precision braking in diverse conditions.
