Fiberglass Biaxial Cloth and Tape FAQs


What is Biaxial Fiberglass?

Biaxial fiberglass is a type of non-woven fiberglass fabric. Instead of a conventional weave pattern, biaxial cloths two layers lie at a 45-degree fiber angle to each other. The two layers are stitched together with sturdy polyester yarn.

Biaxial glass fabrics properties enable you to lay fiber in any direction, and the cloth conforms to any desired shape. Print-through, where the weave is visible through the gelcoat or paint finish, is less of an issue with this material, and it exhibits increased stiffness compared to woven fabrics.

A 3/4-ounce mat backing adds thickness and bulk. When the biaxial glass with mat backing is used over dents and scratches, the finished product will have a much smoother finish.

During the wetting-out process, you will end up with a superior fiber to resin ratio compared to conventional cloth. Overall, biaxial fiberglass is most useful for reinforcing, tabbing, and repair projects.

Biaxial Fiberglass Tape

Biaxial fiberglass tapes fibers are also oriented at 45 degrees, and are held together with lightly stitched thread. This construction produces flat, crimped-together fibers, and results in a product with increased stiffness when stacked up against woven fabrics. Biaxial tape is useful for fiberglass reinforcing and repairs.

What Are the Disadvantages of Biaxial Cloth?

Biaxial fiberglass has several notable disadvantages. It is considerably more expensive than a woven cloth. Second, applying resin to biaxial cloth is more difficult than applying resin to several thinner layers of woven cloth. In addition, too much resin can result in a post-cured brittle laminate.

What Is 1708 Fiberglass?

The term 1708 fiberglass denotes each cloth layers overall weight. For example, 45 biaxial weave cloth weighs 17 ounces for each square yard. The 1708 biaxial fiberglass cloths mat backing weighs 8 ounces for every square yard. Added together, 1708 fiberglass cloth weighs 25 ounces for each square yard.

Is Biaxial Fiberglass Stronger or Better Than Woven Fiberglass Cloth?

Biaxial is great for spot repairs and reinforcing, as it exhibits less print-thru, better resin to fabric ratio, and higher stiffness than woven fabrics. While it is stronger, it is less smooth than cloth. It soaks up a lot of resin and can be too heavy for overhead applications.

What Is the Difference Between Biaxial and Triaxial fiberglass?

The term biaxial means the fiberglass cloth contains two layers of material. The term triaxial means there are three layers of material in the fabric. Each cloths specifications dictate its orientation in different directions.

Biaxial Fiberglass

Biaxial fiberglass is a non-woven fiberglass fabric in which the layers have a 45-degree orientation to each other. Polyester yarn stitches the two layers together, and mat backing adds additional bulk.

Because of biaxial fiberglass specific properties, the fiber adapts to multi-directional placement. The user can easily shape the cloth into desired configurations. In addition, you will not need as much resin compared to a similar project that uses conventional fiberglass cloth.

Triaxial Fiberglass

Triaxial fiberglass is a blend of unidirectional and biaxial fiberglass fabrics. Triaxial fiber tows run at right angles, which boosts the fabrics strength and reduces potentially harmful flexing and strain factors. A thin polyester stitching secures the fiber tows but does not negatively impact the fabrics structural integrity.

Triaxial fiberglass fabric easily absorbs resin. This specialty fiberglass cloth is useful for large fiberglass projects that require surface strengthening while adding very little weight.
