Testing aligned with GB/T 43566-2023 (Artificial Turf Football Fields for Primary and Secondary Schools), reflecting high-frequency use scenarios including daily training, physical education, and small-scale competition. Measurements were obtained using professional testing equipment across five key performance domains.
Ball Interaction Performance
- Ball roll distance: 4.2–7.8 m
- Roll deviation: ≤4.8%
- Rolling resistance coefficient: 0.18–0.22
- Ball rebound rate: 45%–55%, supporting predictable bounce behaviour similar to well-maintained natural grass conditions
Directional tufting technology helps maintain trajectory stability and supports consistent passing and dribbling response during training.
Player Surface Feel and Biomechanical Response
- Fiber material: modified PE/PP composite yarn
- Yarn breaking strength: ≥22 N
- Elongation at break: ≥300%
- Elastic recovery: ≥90%
- Three-dimensional profiled cross-section improves load distribution and reduces localized pressure points
The surface provides balanced cushioning and support for acceleration, deceleration, and directional change during repeated training cycles.
Impact Protection and Safety Indicators
- Shock absorption: 56%–68%
- Vertical deformation: 2.3–5.7 mm
- Surface friction coefficient: 0.42–0.58
These values fall within commonly accepted ranges for school sports facilities, supporting joint protection while maintaining adequate surface firmness for controlled movement.
Structural Stability Under Intensive Use
- Tuft density: 12,800–14,500 tufts/m²
- Fiber embedment depth: ≥20 mm
- Tuft pull-out force: ≥18 N per tuft
- Double-needle tufting structure enhances anchoring stability
- Backing tear strength: ≥1,200 N / 5 cm
- Dimensional stability: ≤0.4%
- Drainage capacity: ≥105 mm/h
Simulated high-frequency use showed fiber layover rates remaining below typical industry reference levels, supporting long-term surface consistency.
Weathering and Environmental Durability
- Xenon arc aging (1,000 h): colour difference ΔE ≤2.0, UV resistance ≥4.5 grade
- Low-temperature bending (−30°C): no cracking after repeated cycles
- High-temperature exposure (60°C, 72 h): no deformation
These results indicate stable outdoor performance across diverse climatic regions.
