Glass Biaxial Fabrics & Tapes

727 Biaxial Tape

17 oz non-woven E-glass fabric. Two layers ±45° fiber orientation are held together by a light stitching. Flat, non-crimped fibers yield reduced print-thru and higher stiffness than woven fabrics. Ideal for repairs, tabbing, and reinforcing.

737 Biaxial Fabric

17 oz non-woven E-glass fabric. Two layers ±45° fiber orientation. For composites, repairs, and reinforcing. Achieves high fiber-to-resin ratio with hand wet out.

Fiberglass Facts


The term “laminating” refers to the process of bonding numbers of relatively thin layers, like plywood, veneers, fabrics, or core material to create a composite. A composite may be any number of layers of the same material or combinations of different materials. Methods of epoxy application and clamping will differ depending on what you are laminating.

Fiberglass Repairs

Recently we revised our most popular instruction manual, Fiberglass Boat Repair & Maintenance, bringing it up to date and expanding it to 146 pages. It contains the very latest fiberglass repair techniques and features complete sections devoted to repairing cracks, holes, damaged skins, cores, keels, and rudders, installing hardware, installing teak veneer decks, gelcoat blister repair and prevention, and final fairing and finishing.
