2mm Thickness Carbon Fiber Tube 10x6x420mm
Product: 2mm Thickness Carbon Fiber Tube with 10×6 mm cross-section, 420 mm length. UV resistant with a 2 mm wall thickness, the tube is made from 100% carbon fiber imported from Japan. This profile provides a compact, rigid option suitable for lightweight frames and structural members in RC and drone applications.
Key considerations: The 2 mm wall delivers a balance between stiffness and weight. Consider the fit for your joints and the adhesive or bonding method you plan to use, as matte or polished surfaces affect coating adhesion.
4pcs Carbon Fiber Tube 6x4x350mm
Product: 4-piece set of carbon fiber tubes, 6×4 mm cross-section, 350 mm length, with 3K roll wrapped twill matte finish. These tubes are designed for applications requiring multiple identical segments, such as frame spars or lightweight chassis components. The matte finish helps with adhesive bonding and paint, while UV resistance supports outdoor use.
Key considerations: Plan for cutting tolerances and ensure your end fittings are compatible with the 6×4 mm geometry. The pack size is advantageous for projects needing several identical sections.
1 Pcs 600mm Carbon Fiber Tube
Product: 600 mm long carbon fiber tube with external 50 mm and internal 47 mm diameters, 1.5 mm wall, and a 3K roll wrapped twill matte finish. It emphasizes high strength and lightweight characteristics, with excellent corrosion, water, heat, and fatigue resistance. The surface is suitable for coating and bonding, and length can be cut to fit project needs.
Key considerations: The larger cross-section increases stiffness, while the modest wall thickness keeps weight down. Ensure your end caps and joining hardware align with the 50/47 mm bore and 1.5 mm wall geometry.
2mm Carbon Fiber Tube 16x12x420mm
Product: 2 mm wall carbon fiber tube, 16×12 mm cross-section, 420 mm length. This tube uses 100% carbon fiber imported from Japan and features UV resistance with a matte surface. The larger oval-like cross-section improves bending stiffness for compact, lightweight frames and structural components in RC craft and drones.
Key considerations: The 16×12 mm size may require specific fittings; verify compatibility with your connector choices and adhesives. The matte surface aids bonding and finishing work.
MECCANIXITY 2Pcs Carbon Fiber Tube 6x8x170mm
Product: A pair of carbon fiber tubes with 6×8 mm cross-section, 170 mm length, glossy surface, and a 3K roll wrapped pure carbon composition. This length is suitable for short, high-strength connections or as lightweight structural members for drones, RC aircraft, and kite spars. The glossy finish may improve paint adhesion and appearance in visible components.
Key considerations: The glossy surface can influence bonding method and surface preparation. Short lengths are ideal for modular builds or testing configurations before committing to longer tubes.
uxcell Carbon Fiber Round Tube 4x2x420mm
Product: Pultruded carbon fiber round tube with 4 mm outside diameter, 2 mm inner diameter, 420 mm length. Pultrusion aligns fibers in one direction for enhanced tensile strength, making it a strong option for RC aircraft components, wings, or spars. It is lightweight, corrosion-resistant, and heat-resistant, with a form suitable for cutting and shaping.
Note: While this entry is from a different listing, it demonstrates another common carbon fiber profile used in RC and modeling. Verify the exact wall thickness and bore for your intended hardware.
Buying Guide: Key Purchase Considerations for Carbon Fiber Tubing
- Profile and dimensions: Oval or round cross-sections affect bending stiffness and fitment. Confirm external and internal diameters, wall thickness, and overall length to match joint hardware and end fittings.
- Material quality: Look for 3K or pure carbon fiber, consistent weave (rolled/twill matte finish), and supplier claims of Japan-origin fibers when relevant for performance expectations.
- Finish and bonding: Matte versus glossy surfaces influence coating, bonding, and paint adhesion. Matte finishes tend to bond better with certain adhesives; glossy surfaces may require surface prep for bonding.
- Mechanical properties: Note tensile strength, stiffness (modulus), and weight. Higher stiffness with lighter weight is typical of higher-grade carbon fiber tubes, beneficial for drones and RC aircraft.
- Manufacturing process: Pultruded tubes have fibers aligned in one direction, providing high axial strength; woven or rolled tubes balance strength in multiple directions. Choose based on load direction and application.
- Weight and length: Determine if the tube’s weight and maximum length suit your project. Consider whether you’ll need to cut to length or pair with end caps and fittings.
- Corrosion and environmental resistance: Carbon fiber resists corrosion and moisture, but resin matrix quality matters for long-term environmental exposure.
- Packaging and multipacks: Packs of identical tubes can reduce project prep time. Ensure the included quantity aligns with the build requirements.
- Compatibility with hardware: Check drill sizes, end caps, and joining methods (epoxy, mechanical fasteners, or clamps) to ensure proper fit with the chosen tubes.
These tubes are suitable for various applications, including RC aircraft and drones, kite spars, model building, and lightweight structural elements. When selecting, balance stiffness, weight, ease of fabrication, and environmental exposure to achieve optimal performance for your project.
