Carbon Fiber Fabric Sleeve – 3k Aerospace Grade Braided Tubing

Our 3k Aerospace Grade Carbon Fiber Fabric Sleeve is a seamless braided tubing engineered for high-performance structural applications. Produced from aerospace-spec 3k carbon fiber tow, this sleeve provides an outstanding balance of stiffness, tensile strength, low weight, and conformity to complex shapes — making it ideal for precision tubes, handles, sporting goods, and custom composite components.

The tubular braid construction eliminates longitudinal seams and allows the sleeve to expand and contract over a wide diameter range. This lets you easily slip it over straight or curved substrates, then tension the braid to achieve tight, uniform fiber alignment before wet-out. Once cured with a quality resin system, the result is a clean, professional carbon fiber finish with reliable aerospace-grade performance.

Technical Details

• Fiber: 3k carbon fiber (aerospace grade)
• Construction: Seamless braided sleeve (Sharx™ style braid)
• Nominal Thickness: ~0.013" (≈0.33mm) dry
• Modulus: ~34 Msi (approx.)
• Tensile Strength: ~640 ksi (approx.)
• Available Sizes: Wide range of nominal diameters for tight, tailored fits
• Compatible Resins: Epoxy (preferred), vinyl ester, and polyester systems suitable for carbon fiber

Key Features & Benefits

• Seamless Coverage: Tubular braid design removes the need for overlapping flat fabric or stitched seams.
• High Stiffness & Strength: Aerospace-grade fibers deliver excellent structural performance.
• Conforms to Complex Geometry: Braid expands and contracts to follow bends, tapers, and varying diameters.
• Clean Cosmetic Finish: Produces a professional carbon fiber appearance suitable for visible components.
• Versatile Processing: Ideal for wet layup, infusion, or advanced fabrication methods.

Typical Applications

• Carbon fiber drive shafts and structural tubes
• Motorsport & aerospace components
• Bike, hockey, and other sports equipment shafts
• Robotics, UAV frames, and automation systems
• High-end handrails, handles, levers, and custom parts

Usage & Sizing Notes

• Select a nominal size that allows the sleeve to expand over your part, then tension it to achieve a snug fit.
• Braided sleeves can shorten in length as they expand in diameter; final length may vary based on how tight the braid is set.
• For most structural applications, we recommend consolidating with vacuum bagging or shrink tape to optimize fiber volume and surface quality.

Ordering

• Width: 50" (127 cm)
• Sold by:Linear Yard — 1 yard = 36" length × full width
• Continuous Lengths: Multiple yards ship as one continuous piece whenever possible.

Note: Because braided sleeves expand and contract, actual coverage length can vary depending on how the product is installed. Small variation in delivered length is normal and accounted for by weight. Always test with a short section to confirm fit and process settings for your specific application.
