Technical Parameters
Key Features & Advantages
| Property | Technical Data | vs. Traditional Sleepers |
|---|---|---|
| Material Composition | Glass Fiber (GFRP)/Carbon Fiber (CFRP) + Polyurethane/Epoxy Matrix | Replaces wood/concrete |
| Weight | 50-70kg/pc (60% lighter than concrete) | Concrete: 250-300kg |
| Service Life | ≥50 years (maintenance-free) | Wood: 15-25y; Concrete: 40-50y |
| Corrosion Resistance | Immune to acid/alkali/salt/insects (ISO 9227 C5) | Wood requires preservatives |
| Electrical Insulation | Volume resistivity >10⁹ Ω·cm (ideal for electrified sections) | Concrete needs insulation add-ons |
| Vibration Damping | 30% better than concrete (ISO 2631) | Reduces noise by 3-5dB |
Comparison with Traditional Sleepers
| Aspect | Composite | Wood | Concrete |
|---|---|---|---|
| Lifecycle Cost | Low (30% savings over 40y) | High (frequent replacement) | Medium (regular maintenance) |
| Eco-Friendliness | 100% recyclable | Chemical treatment risks | High carbon footprint |
| Installation | Manual handling (no crane) | Requires lifting equipment | Heavy crane needed |
