5.7 oz 40" Plain Carbon - 40" Width (By the Yard)

For the ultimate in lightweight stiffness and structural reinforcement, our 5.7 oz. Carbon Fiber Cloth is the industry standard. Featuring a 3k tow (3,000 filaments per fiber) and a tight plain-weave pattern, this fabric is engineered for high-performance surfboard builds where weight reduction and maximum rigidity are the primary goals.

The plain-weave construction ensures the fabric handles easily and wets out quickly, maintaining its weave integrity during lamination. While it offers slightly less "drape" than a twill weave, it is perfectly flexible for standard surfboard curves and rails. Whether you are performing a full carbon wrap, reinforcing a tail patch, or vacuum-bagging a custom build, this 3k carbon provides the professional "stealth" look and ultra-responsive feel that only carbon fiber can deliver.

Key Features:

• 3k Tow: Premium 3,000 filament fibers for superior strength-to-weight ratio.
• Plain Weave: Tight, stable weave that is easy to cut and resists fraying during lamination.
• High Rigidity: Adds significant stiffness to your board, perfect for high-performance EPS/Epoxy builds.
• Versatile Application: Suitable for traditional hand lamination, vacuum bagging, or infusion processes.
• Extra Width: 40" width provides full coverage for wide templates and ensures clean, continuous laps.

Product Specifications:

• Weight: 5.7 oz. per square yard.
• Width: 40" — The ideal span for wide-outline performance boards and longboards.
• Compatibility: Best used with high-quality epoxy resins (such as Resin Research Bio-Clear).
• Shipping: Ships rolled on a heavy-duty tube to maintain a flawless weave pattern.

Pro Tip: When working with carbon fiber, use a clear resin without blue optical brighteners to ensure the blacks stay deep and true. Carbon fiber can be tricky to wrap around tight corners; use a few extra relief cuts or vacuum pressure for the cleanest possible finish.
