The felt consists of randomly distributed fibers that are stitched in a grid-like pattern, which creates a more stable mat with increased dimensional integrity during molding and curing processes. It is typically binder-free, meaning it does not contain any resins or binders that could interfere with the resin system during the lay-up process. This construction also allows for better resin flow, reduced air entrapment, and increased wet-out speed compared to traditional mats with binders.

Glass Fiber Stitched Felt is used extensively in composite applications where high strength, excellent conformability, and consistent wetting of resin are crucial. It is widely used for manufacturing composite parts in industries such as ยานยนต์, marine, construction, wind energy, และ industrial components.

🧪 Typical Technical Data (TDS Style)

✅ Key Features and Benefits

• Binder-Free Construction
  
  Stitched felt does not contain any chemical binders, which significantly enhances resin flow and minimizes air voids during molding. This allows for better wet-out and ensures consistent laminate quality.

• Enhanced Mechanical Strength
  
  The stitching method provides superior tensile strength, resistance to shear forces, และ dimensional stability, making it ideal for structural applications.

• Excellent Resin Compatibility
  
  It works seamlessly with a wide range of resin systems (polyester, vinyl ester, epoxy), making it versatile for vacuum infusion, RTM, hand lay-up, และ spray-up processes.

• Superior Wetting and Conformability
  
  The open, non-woven structure allows for rapid resin penetration and adapts easily to complex mold geometries, making it particularly useful for custom or intricate part shapes.

• Reduced Processing Time
  
  The material’s ability to evenly distribute resin and fiber quickly during the molding process results in faster curing times, which improves production efficiency.

• Dimensional Integrity
  
  The grid-like structure created by the stitching ensures that the mat maintains its shape and size during manufacturing and curing, preventing shrinkage and deformation.

• Enhanced Durability
  
  The use of high-strength polyester yarn in the stitching enhances the overall structural integrity และ long-term durability of the composite material.
