Introduction to Motorcycle brake shoes Carbon Fiber Mixture
Motorcycle brake shoes carbon fiber mixtures are high-performance brake shoes friction materials designed for lightweight yet durable braking systems. These brake shoes mixes integrate carbon fiber reinforcements with ceramic additives and thermosetting resins, offering exceptional heat resistance, reduced wear, and precise braking control. Below is a detailed overview of their technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below highlights key properties of carbon fiber-based brake shoes mixtures:
| Parameter | Specification | Remarks |
|---|---|---|
| Carbon Fiber Content | 20-35% (PAN-based fibers) | Enhances heat dissipation and structural integrity |
| Density | 1.7-2.0 g/cm³ | 30% lighter than traditional metallic mixes |
| Friction Coefficient (μ) | 0.38-0.48 (Dry) | Stable at high speeds and sudden stops |
| Operating Temperature | -40°C to 550°C | Resists thermal fade during aggressive braking |
| Compressive Strength | ≥220 MPa | Withstands high hydraulic pressure |
| Wear Rate | ≤0.25 cm³/MJ | 50% lower wear compared to organic pads |
| Shear Strength | ≥3.5 MPa | Ensures bonding durability under stress |
Key Advantages
- Lightweight Performance
The brake shoes formula reduces component weight by 25-35%, improving motorcycle agility and fuel efficiency. - Superior Heat Resistance
Carbon fibers efficiently dissipate heat, preventing brake fade during prolonged downhill or track use. - Low Dust Emission
Ceramic additives minimize dust generation, maintaining wheel cleanliness and compliance with environmental standards. - Noise Reduction
Optimized brake shoes friction materials dampen vibrations, eliminating squeal common in metallic pads. - Extended Service Life
A wear rate of ≤0.25 cm³/MJ ensures longevity, ideal for high-performance or touring motorcycles.
Storage and Packaging
- Moisture Control: Vacuum-sealed, anti-corrosion packaging prevents carbon fiber oxidation and resin degradation.
- Temperature Limits: Store in a controlled environment (5°C–35°C) to maintain adhesive properties.
- Stacking: Maximum 3 layers to avoid deformation of friction surfaces.
- Shelf Life: 18 months in unopened packaging; reseal after partial use.
Application of Brake Shoes Mixes
The brake shoes mixes are precision-molded under high pressure (18–30 MPa) and cured at 200°C–250°C to bond the carbon fiber matrix to steel backing plates. Post-production testing includes thermal cycling (500 cycles at 550°C) and shear strength validation (≥3.5 MPa) to ensure reliability in extreme conditions. Customized formulations are available for OEMs seeking tailored friction profiles or compatibility with composite brake drums.
By leveraging carbon fiber’s unique properties, these brake shoes friction materials deliver unmatched performance for modern motorcycles, balancing weight savings, durability, and rider safety.
