Introduction to Motorcycle Brake Shoes HD (High-Density) Ceramic Mixture
Motorcycle brake shoes HD ceramic mixtures represent a premium category of brake shoes friction materials, engineered to deliver exceptional braking performance, heat resistance, and durability for high-speed and off-road motorcycles. This advanced brake shoes formula integrates high-density ceramic fibers, advanced binding resins, and friction modifiers to achieve lightweight yet robust braking solutions. Below is a detailed overview of its composition, technical specifications, advantages, and storage protocols.
Technical Parameters
The table below outlines critical properties of the HD ceramic-based brake shoes mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Ceramic Fiber Content | 25-40% (Silicon Carbide, Alumina) | Enhances thermal stability |
| Density | 2.4-2.8 g/cm³ | High-density design reduces wear |
| Friction Coefficient (μ) | 0.38-0.48 (Dry) | Consistent across wet/dry conditions |
| Operating Temperature | -50°C to 800°C | Prevents fade during aggressive use |
| Compressive Strength | ≥280 MPa | Suitable for high-impact braking |
| Wear Rate | ≤0.25 cm³/MJ | 50% lower than standard ceramics |
| Shear Strength | ≥4.0 MPa | Ensures bonding integrity |
Key Advantages
- Ultra-High Heat Resistance
The brake shoes mixture leverages silicon carbide to withstand extreme temperatures (up to 800°C), ideal for racing or mountainous terrains. - Lightweight and Durable
High-density ceramic fibers reduce weight by 20% compared to metallic mixes while maintaining structural integrity. - Low Dust and Eco-Friendly
Asbestos-free composition minimizes hazardous dust emissions, complying with global environmental standards. - Noise Reduction
Ceramic additives dampen vibrations, eliminating brake squeal common in metallic formulation. - Extended Service Life
A wear rate of ≤0.25 cm³/MJ ensures compatibility with long-distance touring or competitive riding (50,000–100,000 km).
Storage and Packaging
- Moisture Control: Vacuum-sealed, anti-static packaging prevents ceramic fiber degradation.
- Temperature Limits: Store at 10°C–35°C; avoid freezing to preserve resin adhesives.
- Stacking: Maximum 3 layers to prevent cracking of high-density friction layers.
- Shelf Life: 18 months in unopened, UV-resistant containers.
Application of Brake Shoes Mixes
The brake shoes mixes are precision-molded under high pressure (25–40 MPa) and cured at 300°C–400°C to bond the ceramic matrix to forged aluminum or steel shoe plates. Post-production testing includes thermal shock cycles (1,000 cycles at 800°C) and shear strength validation (≥4.0 MPa) to meet OEM standards. Custom formulations are available for racing teams requiring tailored friction profiles.
By combining cutting-edge ceramics with rigorous engineering, these brake shoes friction materials redefine reliability and performance for motorcycles in extreme conditions.
