UHMWPE UD fabric is made from high-strength polyethylene fibers aligned in a single direction, which provides:
-
Maximum tensile strength along the fiber axis
-
Superior impact and abrasion resistance
-
Lightweight and flexible properties for easy integration into composites
Comparison Table: UHMWPE UD Fabric vs Woven Fabrics
| Feature | UHMWPE UD Fabric | Woven Fabric |
|---|---|---|
| Tensile Strength | High in fiber direction | Moderate |
| Weight | Ultra-light | Heavier |
| Flexibility | High | Moderate |
| Applications | Ballistic, aerospace, industrial composites | General reinforcement |
2. Step-by-Step Manufacturing Process
①: Fiber Production
-
Sovetl uses gel spinning technology to produce UHMWPE fibers with high molecular orientation, ensuring maximum strength.
-
Fibers are uniform, flexible, and suitable for industrial and ballistic applications.
②: Unidirectional Alignment
-
Fibers are laid out in a single direction to maximize load-bearing capability.
-
Quality control ensures consistent fiber density and tension, critical for high-performance applications.
③: Stabilization & Pre-Treatment
-
Slight thermal treatment to fix fiber positions
-
Optional resin binder to improve handling and lamination
-
Quality inspection: fiber alignment, straightness, and surface smoothness
④: Cutting, Rolling, & Packaging
-
Fabric is cut to standard or custom sizes
-
Carefully rolled and packed moisture-free to preserve mechanical properties
⑤: Integration into Composites
-
Laminated using hot-press or VARTM methods
