1pcs 3K Roll Wrapped Carbon Fiber Square Tube 15x15x13x420MM
Size and construction: External 15x15mm, internal 13x13mm, 1.0mm wall, 420mm length. Made from pure 3K carbon fiber with a matte finish designed for surface coating or adhesive bonding. Lighter and stronger than many metal tubes, while resisting corrosion, water, heat, and fatigue. Best for compact frames and small-profile builds where stiffness is critical but weight must stay minimal.
Best for: Builders seeking a compact, high-strength square frame element for RC models, drones, or camera rigs. Choose this if you need a rigid, easily bonded tube with a matte surface that accepts coatings well. Caution: the inner dimension is slightly smaller than the outer, so ensure your connectors and fasteners fit the 13mm ID.
2pcs Carbon Fiber Tubes 22x20x420MM
Size and construction: Outside diameter 22mm, inside 20mm, 1.0mm wall, length 420mm. Pure 3K carbon fiber with a matte finish suitable for coatings and bonding. Lighter than steel or aluminum while offering high strength and fatigue resistance. The two-pack is convenient for projects needing symmetrical tubes or parallel legs.
Best for: Projects needing medium-diameter, lightweight tubes with consistent tolerances. Better for double-spar configurations or frame sections that require parallel members. Caution: ensure your joints accommodate a 2mm wall tool path when mounting hardware; verify screw lengths match the 1.0mm wall.
1pcs 3K Roll Wrapped Carbon Fiber Square Tube 25x25x21x420MM
Size and construction: External 25x25mm, internal 21x21mm, 2.0mm wall, 420mm length. Features the pure 3K carbon fiber with a twill matte finish for easy surface treatment. Notable for higher load-bearing appplications due to thicker walls, while still offering excellent strength-to-weight ratio.
Best for: Projects requiring a sturdier square tube, such as small frames with moderate loads or where jumpers and braces meet. Choose this if you need additional wall thickness for stiffness. Caution: heavier than thinner-walled options; ensure overall weight targets are met and joints are designed for 2.0mm walls.
FOCMKEAS 2 Pcs 3K Carbon Fiber Tubes 12×10×420mm
Size and construction: Hollow tube, OD 12mm, ID 10mm, length 420mm, wall 1mm. Each tube weighs about 22.5 g. Made from 100% 3K carbon fiber with a roll-wrapped process and a twill matte finish. Notable for very lightweight builds with adequate stiffness for small-scale drones or models.
Best for: Ultra-lightweight assemblies and compact DIY projects where every gram counts. Better for micro drones, small RC devices, or precision instrument frames. Caution: the small inner diameter limits pass-through components and some fasteners; check fit before assembly.
FOCMKEAS 3K Carbon Fiber Tubes, 16×14×420mm
Size and construction: Hollow tube with OD 16mm, ID 14mm, length 420mm, 1mm wall. Crafted from 100% 3K carbon fiber; roll-wrapped with twill matte finish. Described as having excellent heat and fatigue resistance, offering long service life in demanding environments.
Best for: Drones, RC models, and DIY projects needing a balance of stiffness and lightness across a mid-range diameter. Choose this if you require a slightly larger core than 12–14mm tubes but still want low weight. Caution: verify connector compatibility with a 1mm wall; ensure hardware does not over-tighten and crack the tube.
2pcs 18mm x 14mm x 400mm Carbon Fiber Tube Roll Wrapped
Size and construction: 18mm outer, 14mm inner, matte finish, length 400mm. Made with roll-wrapped 3K carbon fiber to deliver a stiff, lightweight tube suitable for compact frames and lightweight rigs. Features low resin content for strength and durability, with a smooth, flawless finish.
Best for: Projects requiring a slightly larger tube than 12–14mm options but still prioritizing weight savings. Better for lightweight drone arms or model components where quick, precise fabrication matters. Caution: length 400mm may require precise cutting; plan for end caps or connectors to seal ends if needed.
Buying Guide: How To Choose Roll Wrapped Carbon Fiber Tubes
Key considerations when choosing roll wrapped carbon fiber tubes include diameter, wall thickness, length, and surface finish. Diameter and wall thickness determine stiffness and load capacity. Length affects handling, mounting space, and compatibility with end fittings. The matte twill finish improves bonding and coatings, while the 3K material provides high strength-to-weight benefits. For drone frames, RC models, or robotics rigs, consider symmetric pairs for balanced loads. Always verify internal dimensions match fasteners and connectors, and account for end treatments such as caps or adhesive bonds.
Frequently asked questions
- What is roll-wrapped carbon fiber tubing? — A carbon fiber tube manufactured by wrapping prepregs around a mandrel, creating high-strength, lightweight hollow tubes with a consistent wall.
- Why choose 3K carbon fiber? — 3K offers excellent stiffness and strength with a classic, recognizable carbon texture, suitable for high-performance builds.
- What size should I choose for a drone frame? — Common drone frame tubes range from 12–18 mm OD; thickness and wall strength depend on load and design requirements.
- Can I cut these tubes to custom lengths? — Yes, most tubes can be cut with an abrasive chop saw; ensure clean ends and proper end treatment after cutting.
- Are matte finishes important for bonding? — Matte surfaces can improve adhesive bonding and paint adhesion in many coating processes.
- What are common cautions when mounting? — Check inner diameter compatibility with bolts and payloads; ensure walls aren’t overtightened to avoid micro-cracks.
