Knitted felt is composed of short-length E-glass fibers (usually 50 mm or 100 mm) arranged in a random orientation and knitted in a lightweight, open-loop structure, providing uniform fiber distribution, excellent conformability to complex molds, and fast resin wet-out. It is especially favored for hand lay-up, vacuum infusion, RTM， 和 spray-up applications in marine, automotive, building, and industrial components.

🧪 Typical Technical Data (TDS Style)

✅ Key Features and Benefits

• Binder-Free Construction
  
  Eliminates chemical binders, improving resin wet-out and environmental safety (VOC-free).

• Superior Conformability
  
  Highly flexible and drapable; ideal for complex contours and curved mold surfaces.

• Even Fiber Distribution
  
  Ensures mechanical consistency and optimal load transfer across the laminate.

• Excellent Resin Penetration
  
  Open structure allows fast resin flow, minimizing dry spots and air entrapment.

• Multi-Process Compatibility
  
  Suitable for RTM, vacuum infusion, spray-up, compression molding, and hand lay-up.

• Improved Laminate Finish
  
  Soft surface structure reduces print-through and supports smooth finishing.

• Lightweight with Good Loft
  
  Maintains a low weight-to-strength ratio with added insulation benefits.
