Grandmaster - 12K, 10x10 Carbon Fiber Fabric

Take Plain Weave Carbon to the Next Level

This brawny, 12K carbon fiber is a bold, hardworking version of our traditional plain weave, with every thick yarn of fabric like a glossy brush stroke. Its high-contrast surface features both brilliant highlights and contrasting deep, dark shadows

Choose Grandmaster for projects that require a robust appearance, perfect for the hood of a car, a motorcycle fender, or snowboard. The 12-K, plain weave of the Grandmaster will keep it from being as conformable to complex shapes as a lighter fabric.


  • Incredible design perfect for automotive aesthetics
  • 50" wide fabric
  • Wets out quickly and easily/li>
  • Fatigue resistance for durable strength


  • The pattern does not affect the strength of this fabric. Patterned weaves feature more "floats," or areas where yarn being woven in one direction floats on top of yarn being woven in another direction. This makes for less bending in the yarn, further supporting the ultimate tensile strength of the carbon fibers themselves.
  • A single layer of the Grandmaster can also be used with standard carbon fabric or even fiberglass.
  • To maximize strength properties, use with an epoxy, like our System 2000 Epoxy Resin (#2000).

The weave is of heavier wefts than I had anticipated. Will make for a bulky yet sturdy, heavy cover.

Grandmaster - 12K, 10x10 Carbon Fiber Fabric This fabric is sold by the linear yard, either as a prepackaged quantity or by continuous yardage. Prepacks This fabric is available in pre-cut lengths that measure one yard (#3221-A, roll), three yards (#3221-B, roll), and five yards (#3221-C, roll). Each is packaged and sold separately. For your convenience, these "prepacks" can be purchased in any combination. However, if the length for any one fabric totals 10 yards or more, we suggest you purchase it in continuous, "cut to length" yardage. Continuous, "Cut to Length" Yardage If you know in advance that you intend to purchase 10 yards or more of any one fabric, it should be ordered in continuous, "cut to length" yardage. In this case, fabric will be cut once according to the total yardage ordered, and customers receive a price-per-yard discount as compared to prepacks. Quantity discounts continue to deepen as the yardage increases for any one cut of one fabric.
