High-Performance Glass Fiber Stitched Mat for Composite
Applications
Product OverviewGlass Fiber Stitched Mat is engineered from chopped E-glass strands or woven roving, precision-cut and randomly dispersed before
being stitched with polyester or carbon fiber threads. This innovative material combines directional strength from woven roving and multi-directional reinforcement of chopped strand mats, making it ideal for enhancing mechanical
properties in composite manufacturing. Compatible with unsaturated
polyester, vinyl ester, and epoxy resins, it serves as a critical
material for industries requiring durability and lightweight
solutions.
Key Features & BenefitsOptimized Structural IntegrityUniform Fiber Distribution: Ensures consistent mechanical performance with ≤5% thickness
deviation . High Wet Tensile Strength: Maintains >30 MPa tensile strength even when fully saturated . Directional Customization: Available in unidirectional or bidirectional configurations for
targeted load-bearing applications.
Process CompatibilityRapid Resin Penetration: ≤60-second impregnation time for efficient RTM and pultrusion
processes . Cold Storage Stability: Remains workable for 24+ hours at -18°C, extending production
timelines . Minimal Void Formation: Open-weave structure reduces air entrapment during curing .
Industrial-Grade DurabilityTemperature Resistance: Operates effectively from -60°C to +150°C . Chemical Resistance: Withstands exposure to oils, solvents, and acidic environments .

Packaging & DeliveryStandard PackagingPrimary: Rolled on 76mm diameter paper tubes, wrapped in PE film to prevent oxidation . Secondary: Packaged in moisture-resistant cardboard boxes with desiccant packs. Bulk Orders: Stacked on pallets (max 2 layers) with stretch wrap for secure
transit.
Custom SolutionsJumbo rolls (width: 1200–3200mm, length: 500–1000m) for large-scale
manufacturing. Climate-controlled containers for international shipments.
Storage GuidelinesEnvironment: Store in cool, dry warehouses (15–35°C, 35–65% RH) . Protection: Avoid direct sunlight, chemical vapors, and mechanical
compression. Shelf Life: 12 months if unopened and stored properly. Handling: Thaw gradually at room temperature (avoid rapid warming to
prevent delamination).
