Fiberglass Woven Roving is bidirectional fabric made byinterweaving direct roving. Can be compatible with unsaturated polyester, vinyl ester, epoxy and phenolicresins.The area weight is from 200g/m2 to 1200g/m2The width is from 50mm-3000mm.
It is widely used in hand lay-up, pultrusion, filament winding, and resin infusion processes for products such as boats, automotive parts, wind turbine blades, and tanks.
Its coarse weave structure allows rapid resin wet-out, making it ideal for building thick laminate layers efficiently. Woven roving also improves impact resistance, stiffness, and overall durability in a wide range of composite structures.
As a leading manufacturer, we offer woven roving in various areal weights to meet the reinforcement and thickness requirements of our industrial clients. Each weight option can be tailored for different resin systems and manufacturing processes, ensuring consistent quality and high-volume production capability.
Woven Roving 600 (≈18 oz/yd²)
Medium-weight fabric suitable for most structural laminates. It offers a good balance between strength, flexibility, and resin wet-out.
Woven Roving 800 (≈24 oz/yd²)
Heavy-duty fabric ideal for thick, high-strength laminates such as boat hulls, tanks, and large FRP panels. Provides higher stiffness and impact resistance.
Each weight option can be combined with different resin systems (polyester, vinyl ester, epoxy) and processing methods such as hand lay-up, RTM, and pultrusion to achieve the desired mechanical and cost performance.
Woven fiberglass products offer versatile solutions for reinforcement, insulation, and structural optimization in composite applications. By selecting the appropriate type—ranging from standard woven roving to fine or heavy yarn tapes, or composite combination mats—manufacturers can tailor strength, dimensional stability, and resin compatibility to meet specific performance requirements. The following four product types represent the core options for optimized design and manufacturing efficiency in marine, electrical, and industrial applications.
Width: Standard 300-500 mm, customizable Grammage: Medium to heavy 600 g/m² Material: E-glass fiber Weaving: Plain
Description:
Woven roving can be slit to a certain width on request.Usually we call it woven roving tape.Woven roving tape can be used for boat building,pultrusion and FRP products.
