1. Characteristics of glass fiber woven roving

What is glass fiber woven roving? Glass fiber woven roving, also known as glass fiber plain cloth or woven cloth, is a high-strength reinforced material made by interweaving E glass fiber direct roving through plain weave, twill weave and other weaving methods. The roving surface is in a regular checkered shape, the fibers are evenly distributed, and it has good mechanical properties and resin impregnation. Its core characteristics are as follows:

High strength and good stability: the warp and weft roving are both high-strength continuous glass fibers with strong tensile and bending resistance;

The roving surface is flat and the thickness is uniform: the weaving is dense, the ply is smooth, and it is conducive to interlayer bonding;

Good impregnation: the resin can easily penetrate the fiber structure, enhancing the density and strength of the product;

Can be used in multiple layers: adapt to the needs of composite material structure design and enhance directional performance.

2. Advantages of glass fiber woven roving

Excellent reinforcement effect: significantly improves the impact resistance of composite materials;

Good compatibility: suitable for various thermosetting resins such as UP, VE, EP, etc.;

Adaptable to various processes: suitable for hand lay-up, molding, winding, RTM and other molding methods;

Flexible laminate design: can be used with chopped strand mat, surface mat, composite mat to meet structural/surface requirements.

3. Typical application scenarios

Shipbuilding: large composite structures such as hulls, decks, and hatches;

Wind energy equipment: load-bearing parts such as the main beam and shell of wind turbine blades;

Automotive industry: body shell, bottom plate, energy storage cabin, etc.;

Sports equipment: skis, bicycle frames, surfboards, etc.;

Building components: fiberglass plates, anti-corrosion structural parts, skylight ceilings, etc.

4. Selection and use guide

Main parameter reference:

Weight (g/㎡): Commonly 500g, 600g, 800g, 900g, etc.;

Width: 1m, etc., can be customized;

Weaving type: plain (commonly used), twill (softer and more docile);

Suggestions for use:     

Avoid air bubbles when laying to ensure that the fibers are fully infiltrated;

Keep the storage environment dry and ventilated to avoid moisture absorption on the fabric.

Combine with chopped strands of felt and surface felt to enhance the mechanical properties and surface finish of the product.

5. FAQ 

What is the difference between woven fabric and chopped strand mat?

Woven fabric is a woven structure composed of crisscrossed glass fiber bundles. It is mainly responsible for providing high mechanical strength in the warp and weft directions and is usually used for the structural layer and stress-bearing layer of the product.

Chopped strand mat is a random short fiber layer with uniform reinforcement in all directions. Its main function is to improve the overall resin impregnation, layer uniformity and impermeability. In the manufacture of composite materials, woven fabric and chopped strand mat are usually used in combination. The former provides strength and the latter ensures molding quality and flatness.

What is the difference between woven and biaxial roving?

Ordinary woven roving is a traditional plain weave structure with 90° warp and weft interlaced. It has a simple structure and mature technology and is widely used in flat or simple curved products. Biaxial fabric is a non-woven structure. Two layers of fibers are sewn or bonded together at different angles (such as ±45° or 0°/90°). It is suitable for large-area, high-strength or complex structural parts, especially in wind turbine blades, hulls, building reinforcements and other fields, to improve mechanical properties in different directions.

How strong is woven fabric?

As a basic reinforcement material, the tensile strength and bending strength of the woven fabric are at a relatively high level among similar materials, especially in the 0° and 90° directions, which can provide stable mechanical properties.

However, due to the certain bending in the woven cross section, the strength is not as extreme as that of unidirectional ply or multi-axial fabric, but for most structural layer applications, it can already meet the balance between strength and cost.
