Specifications

Biaxial Fabric – This stitch-bonded, non-crimp reinforcement combines unidirectional warp (0°) and weft (90°) fibers for enhanced stiffness without adding weight or laminate thickness. Ideal for high-performance structural laminates, biaxial fabric is commonly used in boat hulls, trailer panels, wind turbine blades, sports gear, and bridge decks.

Each roll includes 17 oz biaxial cloth with a ¾ oz chopped strand mat backing. Roll dimensions: 50″ wide × approximately 52 yards long.

This same fabric is also available in 6" and 12" widths as a 1708 biaxial fiberglass tape.

FAQ

Frequently Asked Questions

What is biaxial fiberglass?

Biaxial fiberglass is a type of fiberglass fabric where the fibers are stitched together in two directions—typically at +45° and -45° angles or 0° and 90°. Unlike woven fiberglass, the fibers in biaxial cloth are not interlaced, but rather laid flat and stitched, which improves strength and drapability.

What is the difference between 1708 and 1808 biaxial fiberglass?

The number refers to the weight: 1708 is 17 oz stitched fabric with an 8 oz chopped strand mat backing. 1808 is similar but with 18 oz stitched fabric. The mat backing improves bond strength with polyester resin.

What is the benefit of using biaxial fiberglass over woven cloth?

Unlike woven cloth, biaxial fiberglass is stitched, not woven, so it lays flatter, wets out faster, and provides superior load distribution without crimped fibers.

Can I use 1708 biaxial fiberglass with epoxy resin?

Yes, you can use epoxy resin with 1708 biaxial fiberglass because it has a stitched mat instead of a chemical binder like chopped strand mat.

How heavy is 1708 Biaxial Fiberglass?

Each yard of the 1708 biaxial fiberglass weighs about 2 lbs.

How much epoxy resin do I need for 1708 biaxial fiberglass?

To wet out a full 50" wide yard of the 1708 biaxial fiberglass you'll need about 30oz of epoxy resin. This is a thick layup with stitched core and mat, which yields a strong result.

What types of resins are compatible with biaxial fiberglass?

Biaxial fabric works well with polyester, vinyl ester, and epoxy resins. Be sure to choose the right resin system for your project and material compatibility.
