Product Overview
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.

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.
Packaging Method
Industrial triple-layer protection for global shipping integrity:
- Roll Configuration:
- Wound on Ø 76mm kraft paper tubes with heat-sealed edges to prevent fiber shedding.
- Standard roll length: 20-100 m (adjustable by grammage), max. roll weight: 80kg.
- Sealed Encapsulation:
- Inner Layer: Anti-static PE film moisture barrier.
- Outer Layer: 5-ply corrugated box labeled "↑ Moisture-Proof, Handle with Care".
- 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.
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.
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.
