This mat is binder-free, allowing for more efficient resin absorption, and faster and more uniform wet-out during molding processes. The use of stitching yarn also provides a more stable and durable structure compared to other glass fiber mats. The nonwoven structure ensures excellent conformance to molds, even those with complex geometries, making it suitable for a variety of molding techniques such as hand lay-up, vacuum infusion, RTM, and spray-up.

Glass Fiber Stitched Mat is used in many composite applications, including those in the automotive, marine, construction, wind energy, and industrial sectors, where high-strength and lightweight materials are required for high-performance parts.

🧪 Typical Technical Data (TDS Style)

✅ Key Features and Benefits

• Binder-Free Construction
  
  The absence of binders ensures excellent resin compatibility, allowing for rapid resin absorption and minimal interference with the resin matrix, resulting in uniform composite properties.

• Superior Dimensional Stability
  
  The mechanical stitching used to hold the fibers together provides greater dimensional stability during both the molding and curing processes, helping to maintain part integrity throughout production.

• High Tensile Strength
  
  Glass Fiber Stitched Mat offers excellent tensile strength, which improves the final composite's ability to withstand mechanical stresses, including bending, stretching, and compression.

• Reduced Air Entrapment
  
  The open structure created by the stitching allows for faster resin wet-out and helps minimize air pockets, ensuring a high-quality finish and uniform laminate structure.

• Customization for Specific Applications
  
  The weight, fiber length, and stitching configuration of the mat can be customized to meet the specific requirements of different applications, ensuring optimal performance for each product.

• Excellent Conformability
  
  The mat is highly flexible and can easily conform to complex mold geometries, ensuring efficient part production even in intricate mold designs.

• Faster Curing Times
  
  The high resin uptake and low binder content result in reduced curing times, which speeds up the production process and enhances manufacturing efficiency.
