Fully compatible with Polyester, Vinyl Ester, and Epoxy resins, these premium reinforcements are the go-to choice for manufacturing FRP boats, insulation panels, anode tubes, and automotive parts.
Why Choose Our Stitched Reinforcements?
Precision Directional Strength
By offering customized fiber orientations (0°, 90°, +45°, -45°), our unidirectional fiberglass fabric and biaxial fiberglass fabric allow engineers to place load-bearing strength exactly where the composite part needs it most.
Optimized for Fast Wet-Out
Designed without weaving binders, our fiberglass stitched mat and epoxy compatible stitched fabric ensure rapid resin penetration. They are highly conformable and act as the perfect RTM fiberglass fabric for closed-mold and hand lay-up processes.
Our specialized multi-axial and stitched product portfolio includes:
Continuous Pultrusion & Winding: The ultimate fiberglass fabric for pultrusion. Our single warp UD fabrics and combo mats serve as the ideal FRP pultrusion fabric for high-pressure pipes, pultruded profiles, and filament-wound tanks.
Heavy-Duty Structural: Complex triaxial fiberglass fabric and versatile multiaxial fiberglass fabric (including Multiaxial Core Mats) engineered to withstand extreme torsional and bending stresses.
Marine Excellence: Specialized Woven Roving Combo Mats and E-Glass Woven Roving designed specifically as reliable boat building fiberglass fabric to prevent hull delamination and reduce overall vessel weight.
