High Performance Glass Fiber Stitched Mat A Revolutionary Force in Composite Materials​

​1. Product Overview: Glass Fiber Stitched Mat​

​Definition & Structure​
Glass Fiber Stitched Mat is a ​non-woven, binder-free reinforcement material​ composed of randomly distributed ​E-glass chopped strands​ (length: 50mm, SiO₂ 52–56%, Al₂O₃ 12–16%), mechanically bonded by ​polyester stitching yarn​ instead of chemical binders. This structure preserves fiber integrity, enables rapid resin saturation (≤60 seconds for polyester/epoxy), and delivers isotropic mechanical properties with 30% higher interlaminate shear strength than woven fabrics.

​Core Advantages:

• ​Process Adaptability: Compatible with hand lay-up, pultrusion, RTM, and filament winding, reducing layering time by 40%.
• ​Mechanical Performance: Tensile strength up to ​220N/50mm​ (EC340 grade), impact resistance increased by 44%, wet strength retention >90%.
• ​Safety & Eco-Friendly: Non-combustible (Fire Class A1), acid/alkali-resistant (except HF), SGS-certified.

​Application Fields:

​2. Technical Specifications Table​

Compliant with ​ISO 3374/GB/T 9914.1, standard and customizable grades are listed below:

​Customization Options:

• ​Hybrid Structures: e.g., EMK600/300 (300g/m² chopped mat + 600g/m² woven roving), 50% higher interlaminate shear strength.
• ​Acid-Resistant Variants: Medium-alkali glass fibers for chemical tank linings.

​3. Packaging Method​

Industrial triple-layer protection for global shipping integrity:

1. ​Roll Configuration:
   • Wound on ​Ø76mm kraft paper tubes​ with heat-sealed edges to prevent fiber shedding.
   • Standard roll length: ​20–100 m​ (adjustable by grammage), max. roll weight: 80kg.
2. ​Sealed Encapsulation:
   • ​Inner Layer: Anti-static PE film moisture barrier.
   • ​Outer Layer: 5-ply corrugated box labeled “↑ Moisture-Proof, Handle with Care”.
3. ​Shipping Units:
   • ​Palletized: 12–16 rolls vertically or 6–9 rolls horizontally per wooden pallet (1200×1000mm).
   • ​Container Load: 18–22 pallets per 40HQ container (~25 tons), stretch-film secured, max. stacking height: 2 layers.

​4. Storage Guidelines​

Optimal conditions to ensure ​12-month shelf life​:

• ​Environmental Control:
  • ​Temperature: ​10–35°C​ (critical thresholds: <5°C causes brittleness, >40°C degrades stitching yarn).
  • ​Humidity: ​35–65% RH​ (dehumidified warehouses; no outdoor exposure).
• ​Handling Protocols:
  • Store rolls ​vertically on pallets, stacking ≤3 layers; use cushioning boards for flat storage.
  • Isolate from UV radiation, acidic fumes, and solvents (install blackout curtains).
• ​Post-Opening:
  • Consume within ​72 hours; reseal unused material in heat-sealed bags with opening time labeled.

​5. Service Commitment​

✅ ​Tailored Solutions: Grammage (225–1200 g/m²), width (up to 3600 mm), hybrid structures (chopped mat + woven roving).
✅ ​Quality Assurance: Batch-specific ISO test reports (tensile strength, resin uptake rate).
✅ ​Global Logistics: FOB/CIF terms; moisture-controlled containers + GPS tracking.
