4 oz Fiberglass Fabric

For orders placed before 2:30PM EST
Conformable and Lightweight Fabric for General Use
This 4-ounce Plain Weave Fiberglass Fabric is our most popular selection for use as a surface fabric, with enough body to be easily handled. This fiberglass wets out to a transparent, protective barrier, and can be used to prevent print-through of heavier fabrics underneath. It is often chosen for strip-built canoes and final layering over moldless designs.
Like other plain weaves, it delivers uniform strength in both horizontal and vertical directions, with warp and fill yarns at 0 and 90 degrees, respectively.
Features
- Most popular surface fabric
- Uniform horizontal and vertical strength
- Minimize print of laminate fabrics
- Cures transparent
Tips
- Ideal for a final layering over moldless designs
- Great for building cedar or strip-built canoes and kayaks
- Orient this fabric so that yarns run parallel to expected loads.
- During lay-up, add layers at alternating 45-degree angles to maximize strength.
- Use with epoxy resin, polyester resin, or vinyl ester resin to produce composite parts of excellent strength, low weight, and great cosmetics.
