Introduction to Motorcycle Brake Pads NAO (Non-Asbestos Organic) Mixture
Motorcycle brake pads NAO (Non-Asbestos Organic) mixtures are eco-friendly brake pads friction materials designed to replace traditional asbestos-based formulations. Combining organic fibers, resins, and ceramic additives, this brake pads formula prioritizes safety, low noise, and environmental sustainability while maintaining reliable braking performance. Below is a detailed overview of its composition, technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below outlines key properties of NAO-based brake pads mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Organic Content | 40-60% (Aramid, Cellulose, Rubber) | Ensures flexibility and noise reduction |
| Friction Coefficient (μ) | 0.35-0.45 (Dry) | Stable under moderate temperatures |
| Operating Temperature | -30°C to 350°C | Suitable for urban and light-duty riding |
| Density | 1.8-2.2 g/cm³ | Lightweight design for reduced unsprung mass |
| Wear Rate | ≤0.8 cm³/MJ | Extended service life with minimal rotor wear |
| Compressive Strength | ≥150 MPa | Resists deformation under braking force |
| Noise Level | ≤70 dB | Optimized for vibration damping |
Key Advantages
- Eco-Friendly Composition
The brake pads mixture eliminates asbestos, reducing health risks and environmental impact. - Low Noise and Vibration
Organic fibers and rubber in the brake pads friction materials absorb vibrations, ensuring quiet operation. - Rotor-Friendly Performance
Ceramic additives minimize abrasive wear on brake rotors, lowering maintenance costs. - Thermal Stability
Withstands moderate heat buildup, ideal for frequent stops in urban environments. - Cost-Effective
Simplified brake pads formula reduces production costs compared to high-metallic or ceramic alternatives.
Storage and Packaging
- Moisture Protection: Packaged in vacuum-sealed, anti-humidity bags to prevent resin degradation.
- Temperature Limits: Store below 40°C to avoid premature curing of organic binders.
- Stacking: Maximum 10 layers to prevent deformation of friction layers.
- Shelf Life: 18 months in unopened, UV-resistant packaging.
Application of Brake Pads Mixes
NAO brake pads mixes are molded under moderate pressure (10-20 MPa) and cured at controlled temperatures to ensure uniform bonding between the friction layer and backing plate. Post-production, they undergo rigorous testing for shear strength (≥2.5 MPa) and thermal cycling resistance. Customizable formulations allow adjustments in organic-to-ceramic ratios to meet OEM or aftermarket requirements.
This blend of organic resilience and ceramic-enhanced durability makes NAO mixtures a preferred choice for riders prioritizing safety, comfort, and environmental responsibility.
