Fiberglass Stitch Bonded Fabric (Stitched Mat)
Setting the global standard for multi-layer composite reinforcement, POLYMER operates as a premier biaxial fiberglass stitched mat manufacturer. Our premium fiberglass stitch bonded fabric is meticulously engineered by mechanically locking 0° and 90° direct rovings with an optional layer of chopped strands or polyester tissue, creating a highly robust, binder free stitched combo mat.
Designed without chemical adhesives, this advanced structural textile guarantees extremely rapid resin wet-out and flawless compatibility with Epoxy, Vinyl Ester, and Polyester systems. It serves as the ultimate RTM process fiberglass stitched mat and heavy-duty stitch bonded fiberglass for wind blades, delivering exceptional multi-directional strength and fatigue resistance for demanding marine and pultrusion applications.
Setting the global standard for multi-layer, binder-free composite reinforcement, POLYMER's premium fiberglass stitch bonded fabric (widely referred to in the industry as a high-performance fiberglass stitched mat) is a highly advanced structural substrate. As a leading biaxial fiberglass stitched mat manufacturer, we meticulously engineer this fabric by aligning continuous direct rovings perfectly straight in both the 0° (warp) and 90° (weft) directions. These non-crimp layers are then mechanically locked together using a strong, non-structural polyester stitching yarn.
To meet specialized engineering requirements, this versatile binder free stitched combo mat can be seamlessly stitched with an additional layer of chopped strands or a protective polyester tissue. Completely devoid of chemical binders, it acts as a remarkably fast wet-out multiaxial fiberglass fabric, ensuring unparalleled resin flow and profound compatibility with Epoxy, Vinyl Ester, and Polyester resins. It serves as the ultimate backbone for stitch bonded fiberglass for wind blades, high-pressure RTM (Resin Transfer Molding) components, and continuous heavy-duty pultrusion processes.
Whether you are infusing massive wind turbine blades or pulling high-strength architectural profiles, our engineered stitch-bonded fabrics secure your structural integrity:
For Wind Energy & Aerospace: Leverage our non-crimp stitched fiberglass fabric. The straight, uncrimped 0°/90° fibers deliver ultimate fatigue resistance and stiffness, forming the critical load-bearing spars of modern wind turbines without succumbing to micro-cracking.
For RTM & Closed Mold Operations: Deploy our specialized RTM process fiberglass stitched mat. The binder-free construction and stitching micro-channels dramatically accelerate resin injection speeds while preventing fiber wash-out in complex automotive molds.
For Continuous Pultrusion Lines: Utilize our fiberglass combo mat for pultrusion profiles. By stitching a chopped layer to the biaxial base, it provides extreme longitudinal stiffness and transverse tear resistance, ensuring flawless I-beams and grating.
For High-Performance Marine Hulls: Source directly from a verified bulk fiberglass stitched mat supplier. We offer fully customizable weights (from 400g to 1500g), custom slit widths, and highly competitive factory-direct export pricing for luxury yacht building.
Mechanically stitched without chemical adhesives. This eliminates resin incompatibility, ensures a cleaner laminate, and fully supports advanced Epoxy infusion processes.
Fibers lie perfectly straight at 0° and 90° without interlocking crimps. This delivers instantaneous load-bearing capabilities and ultimate fatigue resistance under stress.
The absence of binders combined with precise stitching creates micro-channels, allowing resins to rapidly impregnate the mat, drastically reducing RTM injection cycle times.
Unlike standard emulsion mats, the robust stitched structure completely prevents fibers from "washing out" or shifting when resin is injected under high pressure.
