Fiberglass Fabric

Among reinforcements, Fiberglass Fabrics continue to be the most commonly used reinforcement in the composites industry today. Generally, they are the least expensive among reinforcements and offer ease in handling. And when combined with resin, deliver composite parts with excellent strength, low weight, and great cosmetics.

All Fiberglass Fabrics are woven for fiber orientation, and each fabric features its own unique weight, strength, and fabric characteristics, which should be considered before starting any project.

Style 6781 S2-Glass
9 oz/sq yd, 50" Wide, 0.010" Thick, 58 x 54 8H Satin Weave


This 9-ounce fabric selection is much like our #543 9-ounce E-Glass, except that it is woven from S2 fibers. As a result, this S2-Glass features extraordinary strength with a superior look and finish. Style 6781 is one of the most popular fabric for modern aerospace applications.

Before starting the lay-up process, fabricators should consider:
  • Satin weaves are flatter and conform to shapes easily, but note that are also more easily distorted than other weaves.
  • Each side of this fabric is either largely fill or warp fibers, so opposite sides will look much different. To produce a symmetrical laminate, invert half the plies.
  • To maximize strength for your part, use with an epoxy, like our System #2000. Fiberglass composites also boast low weight and great cosmetics.


Fibre Glast is committed to ensuring that every roll of fabric we handle is First Quality and manufactured to the highest standards, so that you can expect the same finish, sizing, and handling characteristics every time you order.

Woven Roving
18 oz/sq yd, 50" Wide, 0.025" Thick, Basket Weave


Woven Roving provides an inexpensive means to laminate large, flat areas that call for rapid build-up and high strength reinforcement. It is not suited for applications that require conformability.

Fibers are bundled into warp and fill yarns that run at zero and 90 degrees, delivering solid strength in two directions for finished composite parts. Fabricators should orient yarns to run parallel with expected loads, and alternate consecutive plies at 45 degrees to maximize strength.

Woven roving is often used with chopped strand mat (CSM) to reinforce other materials and make repairs. In this specific case, it should be used with polyester or vinyl ester resin only, as the CSM keeps it from being compatible with epoxy. Otherwise, woven roving is compatible with all of the resins on this site.

20 oz Tooling Fabric
20 oz/sq yd, 38" Wide, 0.030" Thick, 39 x 21 Mock Leno Weave


When you're looking to build thickness into a mold with limited time, this tooling fabric is the right choice. It is typically placed at the heart of a mold to build bulk, strength, and dimensional stability. In this case, lighter fabrics are generally added as a surface layer to prevent show-through of its more textured weave.

To create the highest quality molds, use with our #1110 Vinyl Ester Resin, or the System #2000 Epoxy.

Typical full roll length is 75 yards. 
Woven Fiberglass Tape
7.5–10 oz/sq yd, Various Widths, 0.015" Thick, 18 x 17 Plain Weave


Woven Fiberglass Tape is ideal for selective reinforcement of fiberglass laminates, sleeve or pipe winding, seams, and molding.

These tapes are referred to as tapes only for their width and appearance—they are not adhesive backed. Their finished edges offer easier handling and a clean, finished appearance, and keep the tape from unraveling.

Tapes are matched to our #243 and #245 fabrics (7.5–10 ounce fabrics). Their plain weave construction builds in uniform strength in both horizontal and vertical directions.

Tapes are meant to be used with a resin, they saturate easily, and are compatible with epoxy, polyester, and vinyl ester.

With the Fibre Glast First Quality commitment, you can expect the same finish, sizing, and handling characteristics every time you order this tape.

Typical full roll length is 50 yards. 

  • Plain Weaves—Least expensive and least pliable, but hold together well when cut
  • Twill Weaves—A compromise between plain and satin weaves; pliable with moderate strength and desirable cosmetics
  • Satin Weaves—Pliable with moderate strength; feature one fill yarn that floats over 3–7 warp yarns before being stitched beneath another; produce flatter fabrics
