Introduction to Motorcycle Brake Shoes Ceramic Mixture
Motorcycle brake shoes ceramic mixtures are high-performance brake shoes friction materials engineered for superior braking efficiency, minimal noise, and environmental sustainability. These brake shoes mixes combine ceramic fibers, metallic alloys, and organic binders to achieve optimal heat dissipation, wear resistance, and consistent friction performance. Below is a detailed breakdown of their technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below highlights key properties of ceramic-based brake shoes mixtures:
| Parameter | Specification | Remarks |
|---|---|---|
| Ceramic Content | 20-35% (Silicon Carbide, Alumina) | Enhances thermal stability |
| Density | 1.9-2.4 g/cm³ | Lightweight for reduced rotational mass |
| Friction Coefficient (μ) | 0.30-0.40 (Dry) | Stable across wet and dry conditions |
| Operating Temperature | -50°C to 650°C | Resists thermal fade |
| Compressive Strength | ≥220 MPa | Withstands high-pressure braking |
| Wear Rate | ≤0.2 cm³/MJ | 50% lower than semi-metallic materials |
| Shore Hardness | 55-70 Shore D | Optimized for disc or drum compatibility |
Key Advantages
- Exceptional Heat Resistance
Ceramic components (e.g., silicon carbide) in the brake shoes formula dissipate heat rapidly, preventing brake fade during aggressive riding or downhill braking. - Low Noise and Vibration
Ceramic particles and organic additives minimize high-frequency squeal, ensuring quiet operation. - Eco-Friendly Composition
Asbestos-free and low-dust emission align with global environmental standards. - Lightweight Design
The brake shoes mixture reduces weight by 15-20% compared to metallic alternatives, improving motorcycle agility. - Extended Service Life
A wear rate of ≤0.2 cm³/MJ ensures durability for urban commuting and long-distance touring.
Storage and Packaging
- Moisture Protection: Packaged in vacuum-sealed, anti-corrosion bags to prevent ceramic oxidation.
- Temperature Control: Store at 5°C–35°C; avoid extreme humidity or direct sunlight.
- Stacking Limits: 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 molded under high pressure (18–25 MPa) and cured at controlled temperatures to bond ceramic fibers to steel backing plates. Post-production testing includes thermal cycling (500 cycles at 650°C) and shear strength validation (≥3.5 MPa). Customized formulations are available for OEMs seeking specific friction profiles or compatibility with advanced braking systems.
By integrating ceramic’s thermal advantages with precision engineering, these brake shoes friction materials deliver reliable, eco-conscious braking performance for motorcycles in diverse riding conditions.
