1pcs Carbon Fiber Tube 50x47x500mm
Reference features: Outside diameter 50mm (±0.1mm), inner diameter 47mm, wall thickness 1.5mm, length 500mm. Made from pure 3K carbon fiber with a matte finish, offering high strength and lightweight properties. Corrosion and fatigue resistance makes it suitable for long-span frames and adhesive bonding processes. It can be cut to length with an abrasive chop saw.
Best for: builders needing a robust, long carbon fiber tube for larger frames, booms, or structural members. The matte surface enhances bonding and coating compatibility.
Limitations: May require precise cutting and alignment tools for accurate length changes; ensure you have proper protective gear when trimming.
1pcs 3K Roll Wrapped Carbon Fiber Square Tube 15x15x13x420MM
Reference features: External 15x15mm, internal 13x13mm, thickness 1.0mm, length 420mm. Built from pure 3K carbon fiber, with a matte finish ideal for surface coating and adhesive bonding. Cuttable to length with an abrasive chop saw. Superior strength-to-weight vs. metal tubes.
Best for: square-profile builds such as drone fuselage sections or frame members requiring rigid, evenly shaped corners. Matte finish eases bonding and aesthetic finishing.
Limitations: Square tubes may require corner-friendly brackets or adapters for seamless joints.
uxcell 2Pcs Carbon Fiber Tubes 4 x 6 x 420mm
Reference features: Diameter 4x6mm (ID 4mm, OD 6mm), length 420mm. Plain weave, glossy surface; pure hollow carbon fiber rod with high strength and corrosion resistance. Easily cut with a chop saw or fine-tooth blade.
Best for: compact RC parts or lightweight drone components where small-diameter tubes are needed. Glossy surface supports smoother aerodynamic profiles and precise joint fits.
Limitations: Very small diameter may limit load-bearing capacity; ensure compatibility with connectors designed for 4–6mm tubes.
4pcs Carbon Fiber Tube 10mmx8mmx420mm
Reference features: Outside diameter 10mm, inner diameter 8mm, thickness 1.0mm, length 420mm. 3K carbon fiber with a matte finish, suitable for coating or bonding. Can be cut to length with standard tools.
Best for: lightweight frames, small-scale robotics, and model-making where a slightly larger tube offers extra rigidity without significant weight gain.
Limitations: Slightly larger diameter may require compatible end fittings or adapters to ensure strong joints.
WHABEST 3K Roll Wrapped Carbon Fiber Tube OD 5mm–10mm × 1000mm
Reference features: Outer diameter 10mm; inner diameter 8mm; length 1000mm; thickness 1.0mm. 100% Japan-import carbon fiber with a plain matte finish. Suitable for long, slender structural components and wing tubes for DIY multi-copters.
Best for: long-span booms or wing spars where a longer tube helps reduce joints. Favorable for precision alignment over extended lengths.
Limitations: Long tubes can flex if unsupported; plan for stiffening brackets or cross-bracing as needed.
2PC Hexagonal Carbon Fiber Tube Hollow 16x14mm 16x13mm 14x12mm
Reference features: Hexagonal carbon fiber tubes designed for RC aircraft and model-building. Hollow construction provides strength while minimizing weight. Precision manufacturing supports consistent dimensions.
Best for: hexagonal frame sections and drone frames needing flat surfaces for mounting components. The hex profile can improve torque resistance and corner support.
Limitations: Hex profiles may require specialized corner brackets or inserts to fit standard fasteners.
Buying Guide: Key Considerations For Hexagonal Carbon Fiber Tubes
- Profile shape and compatibility: Decide between hexagonal, square, or round profiles based on joint design and mounting hardware. Hex and square profiles can offer better torque resistance for certain frames.
- Wall thickness and diameter: Thicker walls increase stiffness and load capacity but add weight. Match tube dimensions to expected loads and available end fittings.
- Finish and bonding: Matte or glossy finishes affect surface prep for coatings and adhesives. Matte finishes generally bond well with coatings and epoxies.
- Length and modularity: Longer tubes reduce joints but may require careful handling and bracing. Consider available cut-to-length options and tool compatibility.
- Material purity: Pure 3K carbon fiber generally provides consistent strength and consistent surface quality for bonding and finishing.
- Application context: For RC aircraft, drones, or robotics, consider vibration tolerance, environmental exposure, and maintenance access.
- Cost vs. performance: Higher-grade carbon fiber offers improved stiffness-to-weight but weigh against budget and project scale.
Frequently Asked Questions
- What is the advantage of a hexagonal carbon fiber tube?
– It offers better torque resistance at corners and can align with hex-based joints, improving rigidity for certain frame designs. - Can these tubes be cut to length easily?
– Yes, most tubes shown are described as cuttable with an abrasive chop saw or fine-tooth blade. - Are these tubes suitable for outdoor use?
– Carbon fiber tubes resist corrosion and weathering, but UV exposure and environmental factors should be considered for long-term outdoor use. - Which tube is best for a lightweight drone frame?
– Small-diameter, high-strength tubes (e.g., 4x6mm or 8x6mm rounds) are ideal for lightweight drone frames, while maintaining rigidity. - Is a matte finish better for bonding than a glossy finish?
– Matte finishes typically provide good bonding surfaces; glossy finishes can also bond well but may require different surface prep. - Do all tubes come with included end fittings?
– End fittings are not listed; check product details or hardware compatibility when designing joints.
