Advantages of Cellulose Fiber in Brake Pads Formula
- Eco-Friendly Composition: As a renewable resource, cellulose fiber replaces asbestos and synthetic polymers, aligning with global environmental regulations.
- Enhanced Structural Integrity: Reinforces the brake pads mixture by improving mechanical strength and wear resistance.
- Noise Reduction: Absorbs vibrations and reduces brake squeal in brake pads friction materials.
- Thermal Stability: Maintains performance at moderate temperatures (up to 250°C), suitable for everyday driving conditions.
- Cost-Effectiveness: Lower production costs compared to synthetic fibers like aramid or ceramic.
Storage and Packaging Guidelines
To preserve the quality of brake pads mixes containing cellulose fiber:
- Packaging: Use sealed, moisture-resistant polyethylene bags with desiccants to prevent hygroscopic degradation.
- Storage Conditions:
- Temperature: 10°C–30°C (avoid thermal cycling).
- Humidity: <65% RH.
- Protect from UV exposure and corrosive chemicals.
- Shelf Life: 12–18 months in unopened packaging.
Key Applications in Brake Pads Ingredients
Cellulose fiber is commonly blended with:
- Reinforcement Materials: Steel fibers, ceramic fibers, and aramid fibers.
- Binders: Phenolic resins or epoxy matrices.
- Fillers: Graphite, barium sulfate, and cashew dust.
This brake pads formula combination ensures balanced friction coefficients (μ = 0.35–0.40), wear resistance, and compliance with automotive safety standards such as SAE J661.
Conclusion
Cellulose fiber is a sustainable and versatile component in brake pads friction materials, offering eco-friendliness, noise reduction, and cost efficiency. Its integration into brake pads mixes exemplifies the shift toward greener automotive technologies while maintaining performance and safety standards.
