3K Roll-Wrapped Carbon Fibre Tube – High-Performance Lightweight Composite Solution

The 3K roll-wrapped carbon fibre tube is a high-performance composite component designed for applications requiring an optimal balance of strength, rigidity, lightweight structure, and aesthetic appeal. Manufactured using 3K carbon fiber fabric—which consists of 3,000 filaments per tow—and utilizing the roll-wrapping process, this tube delivers exceptional mechanical properties and a professional-grade finish. It’s a top choice across aerospace, automotive, drone, robotics, industrial automation, and sports equipment industries.

Material Composition

The tube is made using 3K carbon fiber—the most commonly used fiber type in structural composites. Each tow (fiber bundle) comprises 3,000 individual carbon filaments. This fabric is laid in specific orientations to optimize performance, typically including:

• 0° (axial) for stiffness and compression along the tube's length
• 90° (hoop) for radial strength
• ±45° (bias layers) for torsional resistance

The reinforcement is combined with high-quality epoxy resin to create a strong, durable matrix that bonds the fibers, resists UV and chemicals, and adds environmental resilience.

Manufacturing Process: Roll Wrapping

Roll wrapping is a precision manufacturing technique where pre-impregnated carbon fiber sheets (prepreg) are carefully wrapped around a mandrel in multiple layers. Each layer is strategically oriented to enhance specific mechanical properties. The wrapped mandrel is then placed in a high-temperature oven or autoclave to cure the resin and solidify the structure.

This method offers key advantages

• Consistent wall thickness
• Tight dimensional tolerances
• Superior surface finish
• Custom fiber orientation for strength/torsion control

Compared to pultruded tubes (where fibers run mostly along the length), roll-wrapped tubes provide better torsional strength and multidirectional stiffness, making them ideal for more demanding applications.

Key Features & Advantages

• High Strength-to-Weight Ratio: Carbon fiber is up to 5x stronger than steel yet significantly lighter. These tubes deliver unmatched strength while reducing overall weight in assemblies.
• Excellent Stiffness and Rigidity: Maintains structural integrity under load and resists deformation, making it ideal for load-bearing applications.
• Superior Torsional Resistance: The roll-wrapped structure allows the tube to resist twisting forces, essential for applications like propeller arms or mechanical shafts.
• Corrosion and Fatigue Resistant: Unlike metal tubes, carbon fiber is not affected by rust, moisture, or most chemicals, and it resists fatigue over time.
• Aesthetic Appearance: The visible 3K weave, especially in a glossy or matte finish, offers a professional, high-tech look, often desirable in consumer and industrial applications.
• Customizable: You can tailor the fiber direction, length, diameter, thickness, and finish to your exact specifications, making it highly versatile.
