Fiberglass is the foundation of the composites industry. It is often the best all-purpose choice among reinforcements—and even among traditional building materials, like wood or metal—for creating composite parts with excellent strength, low weight, and dimensional stability. For fabricators, fiberglass is easy to handle, conforms to complex shapes, and generally provides the quickest and most affordable means to build parts and molds, and make repairs. With over 50 years in the industry, it's still the dependable favorite.

Fiberglass Fabric

Fiberglass Fabric

Fiberglass fabrics are in stock for same day shipment. They're affordable, easy to use, and deliver excellent strength, low weight, and solid cosmetics. Choose from a broad product offering, each fabric with unique fabric characteristics to suit your part.


Fiberglass Mat

Fiberglass Mat

Need to build bulk for parts, molds, or even a repair? Fiberglass mat gets the job done quickly and affordably. Randomly oriented strands throughout create equal stiffness in all directions for parts, and mat is ideal for use with other fabrics. Please note: fiberglass mat cannot be used with epoxy resin.


Stitched Fiberglass

Stitched Fiberglass

Stitched fiberglass fabrics maximize directional strength for composite parts. Use them for applications where fast wet-out and strength control are key. Fibre Glast offers unidirectional, biaxial, and triaxial options in a variety of weights and all are in stock for same day shipment.


Chopper Gun & Roving

Chopper Gun & Roving

A chopper gun is used to chop and deposit fiberglass roving and carbon fiber tow into a mold or part. Continuous strands are fed through gun, chopped, and deposited to quickly cover large areas. Resin is applied separately. Glass roving and carbon tow can also be used for pultrusion and filament winding.


Fiberglass Tapes & Sleeve

Fiberglass Tapes & Sleeve

Fiberglass tape and sleeve are perfect for reinforcing strength for smaller areas, and for use with wrapping applications and unique shapes like tubing. When used with resin to create solid composite parts, fiberglass tape and sleeve combine a great strength-to-weight ratio and dimensional stability.


Sample Packs

Sample Packs

Select the best fabric for your composite part. Our Sample Packs are designed to put an array of fabrics in-hand to compare look, feel, and finish. Use them for inspection and testing prior to purchasing larger quantities. Packs contain 4" x 6" swatches and a coupon for a later purchase (patterned carbon measures 12" x 12").


All of our fiberglass reinforcements are made to be used with resin to create hard, composite parts. Check out our complete selection:

  • Woven Fiberglass Fabric – Glass fibers are bundled into yarns, then woven into a number of different patterns, each with its own weight and unique strength characteristics.
  • Fiberglass Mat – A popular choice for building quick thickness into parts and molds, mat consists of randomly oriented glass filaments held together with binder.
  • Stitched Fiberglass – This fabric style features yarns that are stitched, not woven, to avoid crimping and promote strength properties.
