What is fiberglass?

Before we look at the difference between biaxial and woven roving fiberglass, let's first define what fiberglass is. Fiberglass is a material that comprises thin glass filaments. These filaments are tightly woven to form a sturdy cloth that is used to reinforce plastic or create building materials. Fiberglass is prevalent in boats, wind turbine blades, aircraft, and automotive parts.

What is woven roving fiberglass?

Woven roving is one of the most commonly used fiberglass. It is made by weaving heavy roving together, creating a durable, dense mat. The term roving refers to the bundle of glass fibers that are twisted together. Woven roving is known for its superior strength and thickness, making it one of the go-to materials in construction and manufacturing of high-performance applications.

Woven roving comes in various densities, ranging from 300 grams to 1600 grams per square meter. The denser the mat, the stronger the material. However, denser mats will be harder to manipulate, and they require more resin.

What is biaxial fiberglass?

Biaxial fiberglass is a newer form of the traditional woven roving. Unlike woven roving, biaxial fiberglass features fibers that are held together in two directions. This configuration enhances the reinforcement capabilities of the material. The layers intersect at a 45-degree angle, thereby preventing creases or wrinkles that can occur with the traditional woven roving.

Biaxial fiberglass is sold in sheets or rolls, and it comes in a range of densities. Medium density biaxial fiberglass is known for its flexibility, while high-density gives more strength. The material is flexible, easy to manipulate and offers excellent strength per weight compared to woven roving.

What is the difference between biaxial and woven roving fiberglass?

The primary difference between biaxial and woven roving fiberglass is the fiber orientation. Woven roving has fibers that run in one direction, while biaxial fiberglass features fibers that intersect at a 45-degree angle. The fiber orientation in biaxial fiberglass creates a material that is stronger, with greater flexibility and resistance to damage. On the other hand, woven roving is denser and stronger, but it can crease or wrinkle if mishandled.

Another notable difference is the manufacturing process. Woven roving is made by weaving rovings together in a criss-cross fashion, while biaxial fiberglass has fibers laid on top of each other in two directions.

Which fiberglass should you go for?

The choice of fiberglass depends on your project's requirements. If you require a dense, thick fiberglass, then woven roving is your best bet. Woven roving is perfect for boats, automotive parts, and wind turbine blades. However, if you need a flexible, lightweight fiberglass with superior resistance to damage, then biaxial fiberglass is the ideal material. Biaxial fiberglass is popularly used in building and construction of buildings and high-performance parts.

Conclusion

In summary, biaxial and woven roving fiberglass have variations in fiber orientation and manufacturing processes. Woven roving is a dense, sturdy material that is suitable for projects requiring significant reinforcement. On the other hand, biaxial fiberglass is flexible and lightweight, making it ideal for high-performance applications.
