1K, Plain Weave Ultralight Carbon Fiber Fabric

When Strength, Stiffness, Minimum Weight are Key

This unique carbon fabric is used in the most demanding applications which call for maximum strength and stiffness, and where minimum weight justifies the added cost. The plain weave construction delivers uniform strength in both horizontal and vertical directions, and provides for excellent stability and easy handling.

This ultralight fabric is suitable for aerospace, UAVs, competition auto and marine, and light industrial applications.


  • Maximum strength with minimum weight
  • 42" wide fabric
  • Commercial strength T300 fibers
  • High Modulus for superior rigidity
  • Fatigue resistance for durable strength


  • Ideal for for aerospace, UAVs, competition auto and marine, and light industrial applications.
  • To maximize strength properties, use with an epoxy, like our System 2000 Epoxy Resin (#2000).
  • For added conformability, lay up the fabric at a 45-degree bias inside molds.
  • Great for making rigid precision parts with no bulk

Rolled fabrics ship in a long (45", 53", or 62") box. Click below on the "What to expect when you order Fabric" video to see how rolled fabrics are cut and shipped each time you order.
1K, Plain Weave Ultralight 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 (#2363-A, roll), three yards (#2363-B, roll), and five yards (#2363-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.
