Fiberglass combo mat (fiberglass stitch mat with polyester veil) offers several specific advantages, mainly as follows:
1. Excellent Surface Finish
• The polyester veil on the surface can form a smooth, dense layer, reducing the need for post - processing such as grinding or painting. This is particularly important for products requiring high - quality aesthetics (e.g., automotive exteriors, ship hulls).
• It helps prevent resin leakage and fiber exposure, improving the surface integrity and durability of the final product.
2. Enhanced Strength and Uniformity
• The fiberglass stitch mat provides structural strength, while the polyester veil reinforces the surface, creating a composite structure that balances tensile, impact, and shear resistance.
• The stitch - bonded structure ensures uniform fiber distribution, reducing defects like fiber agglomeration and improving the consistency of product performance.
3. Good Resin Compatibility and Infusion Efficiency
• It is compatible with common resins (polyester, vinyl ester, epoxy), and the porous structure of the mat allows resins to penetrate quickly, suitable for processes like hand lay - up, vacuum infusion, and pultrusion.
• The polyester veil can help distribute resin more evenly, reducing air bubbles and voids in the product.
4. Lightweight and Cost - Effective
• Compared to metal materials, it offers high strength - to - weight ratio, helping to reduce the overall weight of products (e.g., automotive parts, ship hulls) while maintaining structural strength.
• The integrated design of the combo mat eliminates the need for additional surface treatment layers, simplifying the production process and reducing costs.
5. Corrosion and Chemical Resistance
• The polyester veil and fiberglass combination enhances resistance to water, chemicals, and atmospheric corrosion, making it suitable for harsh environments (e.g., pipelines, storage tanks, marine applications).
6. Versatility in Processing
• It can be easily cut, shaped, and layered, adapting to complex product designs (e.g., curved hulls, irregular automotive parts).
• Suitable for both small - batch manual production and large - scale automated manufacturing, with strong process adaptability.
These advantages make fiberglass combo mat widely used in industries requiring both structural strength and surface quality, balancing performance and cost - effectiveness.
