This double bias fabric is made of continuous fibers positioned at +45° and -45°, providing strong reinforcement against shear and torsional loads. It is ideal for demanding applications like wind turbine blades and marine panels, offering excellent flexibility for complex shapes while maintaining high structural durability. The fabric weighs 12 oz and includes a 3/4 oz mat on the reverse side, with a width of 50″.

What To Expect When You Order Fabric Rolls

What is 1208 Biaxial Fiberglass?

1208 biaxial fiberglass is a stitched reinforcement fabric made of two layers of 12 oz fiberglass cloth oriented at ±45° angles, with a light ¾ oz chopped strand mat (CSM) backing. It offers excellent multidirectional strength and is compatible with polyester, vinyl ester, and epoxy resins.

What’s the difference between 1208 and 1708 fiberglass?

The main difference is weight. 1208 is lighter (approx. 18 oz total per square yard) compared to 1708 (approx. 25 oz total). 1208 is better for lighter structural needs or where ease of wet-out and flexibility are important, while 1708 offers more bulk and stiffness.
