Introduction to Truck Brake Linings Ceramic Mixture
Truck brake linings ceramic mixtures are high-performance brake linings friction materials designed for heavy-duty vehicles, combining ceramic fibers, non-asbestos reinforcements, and heat-resistant binders. This brake linings formula ensures exceptional thermal stability, reduced wear, and environmentally friendly operation, making it ideal for demanding braking environments. Below is a detailed overview of its composition, technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below summarizes key properties of ceramic-based brake linings mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Ceramic Content | 40-60% (Alumina, Silica, Zirconia) | Enhances heat resistance |
| Density | 2.4-2.8 g/cm³ | Optimized for lightweight durability |
| Friction Coefficient (μ) | 0.30-0.40 (Dry) | Stable at extreme temperatures |
| Operating Temperature | -50°C to 800°C | Minimal thermal fade |
| Compressive Strength | ≥250 MPa | Resists deformation under load |
| Wear Rate | ≤0.3 cm³/MJ | Extended service life |
| Shore Hardness | 55-70 Shore D | Balanced rigidity and noise reduction |
Key Advantages
- Superior Heat Resistance
Ceramic matrices (e.g., alumina, silica) provide unmatched thermal stability, preventing brake fade even at 800°C . - Low Noise and Vibration
The brake linings mixture incorporates ceramic particles to dampen vibrations, reducing squeal and harshness . - Eco-Friendly Composition
Free from asbestos and heavy metals, aligning with global environmental regulations . - Consistent Performance
The brake linings formula maintains a stable friction coefficient across wet, dry, and high-speed conditions . - Lightweight Design
Lower density compared to metallic counterparts reduces unsprung vehicle weight .
Storage and Packaging
- Moisture Protection: Sealed in moisture-resistant shrink-wrap (4 pieces per bag) to prevent ceramic component degradation .
- Temperature Limits: Store in environments below 40°C to avoid binder pre-curing .
- Stacking Guidelines: Maximum 5 layers per carton (24 pieces per carton) to prevent deformation .
- Shelf Life: 24 months in unopened packaging under recommended conditions.
Application of Brake Linings Mixes
The brake linings mixes are molded under high pressure (10-20 MPa) and sintered to form a robust bond between ceramic particles and the backing plate. Post-production testing includes thermal cycling (200–800°C) and shear strength validation (≥3.5 MPa) to ensure reliability . Custom formulations can adjust ceramic-to-binder ratios for specific OEM requirements.
By integrating advanced ceramics and precision engineering, this brake linings friction material delivers unmatched safety and longevity for commercial trucks operating in extreme conditions.
