1808 is the heavy end of our stitched biaxial rack: 18 oz/yd² of 0/90 E-glass stitched over a 3/4 oz chopped strand mat backer, 50 in wide. One ply lays down a thick structural laminate and the mat side wets out fast and buries the weave against the substrate, so you build a transom or a stringer box in fewer plies than woven roving plus mat.

18 oz/yd² stitched 0/90 E-glass with a 3/4 oz CSM backer, about 0.048 in per ply
50 in wide, cut to 1, 3 and 10 yard lengths or take the full roll (about 52 yards)
Runs in polyester, vinyl ester or epoxy
Mat face goes down against the laminate for wet-out and bond
Ships rolled on a corrugated tube so it arrives without creases

For tabbing and seam work in the same fabric, step over to 1708 tape. For a lighter structural ply, 1708 biaxial is the standard pick.

Specifications

Biaxial Fabric. 1808 is a stitch-bonded, non-crimp E-glass fabric: 18 oz/yd² of fibers laid straight at 0° and 90°, stitched to a ¾ oz/ft² chopped strand mat. The fibers lie flat instead of weaving over and under each other, so the laminate is stiff along and across the roll and shows less print-through than woven roving. It's used for hulls, transoms, stringers, decks and other structural laminates.

Each roll includes 18 oz biaxial cloth with a ¾ oz chopped strand mat backing. Roll dimensions: 50″ wide × approximately 100 yards long. Sold by the roll.

Features

0°/90° Biaxial Layup: High stiffness in both longitudinal and transverse directions.
Integrated Mat Backing: ¾ oz chopped-strand mat enhances resin adhesion.
Stitch-Bonded & Non-Crimp: Delivers strength without fiber distortion.
Epoxy-Compatible: Binder-free mat stitches ensure proper wet-out with epoxy.
Efficient Strength Build-Up: Heavy fabric provides bulk and structural reinforcement in fewer layers.
Great for Flat or Slightly Curved Surfaces: Best suited for panels, bulkheads, decks, and high-load areas.

What To Expect When You Order Fabric Rolls

What is 1808 Biaxial Fiberglass?

1808 is a heavy stitched fabric: 18 oz per square yard of E-glass at 0 and 90 degrees, stitched over a 3/4 oz per square foot chopped strand mat backer. One ply builds about 0.048 inch, so transoms and stringer boxes go up in fewer plies. It runs in polyester, vinyl ester or epoxy.

What is the difference between 1708 and 1808 biaxial fiberglass?

1708 is 17 oz per square yard of E-glass stitched at plus and minus 45 degrees with a 3/4 oz per square foot chopped strand mat backer. 1808 is 18 oz per square yard stitched at 0 and 90 degrees over the same 3/4 oz mat, and builds slightly thicker per ply, about 0.048 inch against 0.044 inch. Both run in polyester, vinyl ester or epoxy.

What are typical applications for biaxial fiberglass?

It’s used in marine repairs, boat hulls, surfboards, structural panels, and any application where multi-directional strength is needed.

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.

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.
