Style 7725: 8.5 oz/yd² E-glass in a 2x2 twill. The twill is why you buy it. Two over, two under means the cloth follows shape instead of tenting, so it lays into a compound curve, around a radius or over a corner where a plain weave of the same weight would bridge and trap air.

8.5 oz/yd² E-glass, 2x2 twill, 0/90
Industry style 7725, about 0.0096 in thick per ply
Available 38 in and 50 in wide
Runs in epoxy, polyester or vinyl ester
Cut to 1, 3 and 10 yards, or take the full roll (125 yards)

Handle it square. Twill will rack out of shape if you drag it across the bench, and a racked ply wants to pull the part with it as the resin gels.

What To Expect When You Order Fabric Rolls

Can epoxy resin be used with fiberglass cloth?

Yes, epoxy resin is ideal for wetting out fiberglass cloth and other reinforcements like carbon fiber and Kevlar. It saturates the fabric well and cures into a strong, durable laminate.

Can fiberglass cloth be used on wood or metal?

Yes. With the right resin, fiberglass cloth bonds to wood, metal, foam, and cured fiberglass. Use epoxy for wood and metal, since it grips those substrates far better than polyester. Prep matters more than the cloth: sand to clean, bare material, remove all dust and oil, and wet out the surface before laying the cloth down.

What does the weight (oz) of fiberglass cloth mean?

The weight refers to ounces per square yard. Lighter cloth (e.g., 4oz) is more flexible and used for fine finishing; heavier cloth (e.g., 10oz) provides more strength and bulk.

How do I cut fiberglass cloth?

Use sharp scissors or a rotary cutter on a clean surface. To reduce fraying, run masking tape along the cut line and cut through the middle of the tape, and handle cut edges gently. Keep the cloth dry before layup, since moisture on the glass weakens the resin bond.

What is fiberglass cloth used for?

Fiberglass cloth is used to reinforce composite materials in applications like boat building, surfboard repairs, auto bodywork, and structural laminates. It’s combined with resin to form a strong, lightweight composite.

What’s the difference between fiberglass cloth and chopped mat?

Fiberglass cloth is woven for strength in specific directions, while chopped strand mat is made of randomly oriented fibers and is better for building bulk.
