KRD PERFORMANCE 102mm OD Tube
The KRD PERFORMANCE tube features a 102 mm outer diameter with a 1.5 mm wall thickness, offering a balance of stiffness and lightness. Made with 3K real Japan Toray carbon fiber, it presents a glossy finish that enhances its visual appeal and bonding performance. Expect weight savings in the early 2x to 2.5x range versus equivalent aluminum tubes, depending on length and configuration. The tube can be cut to length with an abrasive chop saw, enabling customization for RC, aeronautics, or mechanical projects.
2pcs Carbon Fiber Tube 25mm OD x 23mm ID x 420mm
This pair of carbon fiber tubes has a 25 mm outside diameter and 23 mm inner diameter with a 1.0 mm wall, measuring 420 mm in length. They are crafted from pure 3K carbon fiber and finished with a matte surface ideal for coating or adhesive bonding. The tubes are noted for high strength and low weight, along with resistance to corrosion, water, heat, and fatigue. They can be cut to custom lengths with an abrasive chop saw, making them suitable for frame rails, drone booms, or structural supports.
2pcs 2MM Wall Thick 22x18x420MM
With an external diameter of 22 mm and internal diameter of 18 mm and a thick 2.0 mm wall, this pair offers robust performance for demanding builds. Like other cncarbonfiber tubes, they use pure 3K carbon fiber and feature a matte finish that suits coating and bonding. They deliver strong stiffness and a lightweight profile, while remaining resistant to environmental factors such as corrosion and heat. Cut-length customization is possible via standard abrasive tools.
2pcs 600MM 16x14x600MM Carbon Fiber Tube
This tube set features a 16 mm outer diameter and 14 mm inner diameter with a 1.0 mm wall thickness, extending to 600 mm in length. It is made from 3K carbon fiber and sports a matte finish suitable for coatings and bonding. The tube delivers compact strength with low weight and is UV resistant, making it a sensible choice for long booms and structural members in RC crafts or small-scale engineering projects. It can be cut to length with standard tools.
ARRIS 12mm x 10mm x 330mm Tube (2PCS)
The ARRIS tubes measure 12 mm outside diameter and 10 mm inside diameter, with a length of 330 mm per piece and a 1 mm wall thickness. They come in a 2-pack and use a 3K roll-wrapped carbon fiber construction with a glossy surface finish. The tubes are designed to be lightweight yet strong, offering reliable performance for RC components, drones, or small structural applications. They are easy to cut to length and compatible with common bonding or mounting methods.
Buying Guide: Large Diameter Carbon Fiber Tubes
Key purchase considerations
– Diameter and wall thickness: Larger diameters increase bending stiffness and load-bearing capacity. A thicker wall boosts stiffness but adds weight. Choose a balance based on your application and mounting space.
– Length and compatibility: Ensure the tube length fits your design or allows cutting to exact sizes without compromising strength. Confirm inner diameter compatibility for your hardware and fasteners.
– Material and finish: Most tubes use 3K carbon fiber with a matte or glossy finish. Matte finishes are often preferred for bonding and coating work, while glossy finishes can be aesthetically advantageous and slightly easier to clean.
– Mechanical properties: Look for high strength-to-weight ratios and corrosion/heat resistance. Real carbon fiber sources (e.g., Toray) often indicate higher quality and consistency than generic copies.
Practical comparisons
– 102 mm vs. 25 mm: The 102 mm tube offers significantly greater stiffness and load-bearing potential, suitable for heavier frames or longer spans. 25 mm tubes are versatile for smaller builds and provide a good balance of weight and strength.
– Wall thickness impact: A 2.0 mm wall dramatically increases rigidity for mid-sized tubes, but it also adds weight. For light, fast-moving applications, a 1.0 mm wall may suffice.
– 12 mm vs. 16 mm vs. 22 mm: Smaller diameters excel in tight spaces and precise assemblies, while mid-to-large diameters (16–22 mm) support more substantial loads and structural stiffness in frames and booms.
Application-specific tips
– Drones and RC aircraft: Prioritize tubes with good torsional stiffness and light weight. Consider 102 mm or 16–22 mm options for booms or landing gear.
– Industrial frames and mounts: Matte finishes aid bonding and coating, while larger diameters deliver higher rigidity for mechanical stress points.
– Custom fabrication: Ensure compatibility with standard cutting tools and mounting hardware. Plan for end-caps, sleeves, or inserts if necessary to fit joints securely.
All products listed are designed to deliver a balance of strength, lightness, and durability, with finishes suitable for coatings and adhesives. For each option, verify compatibility with your project’s tolerances and environmental conditions to maximize performance and longevity.
