Carbon Fiber Tube Products

Roll-Wrapped Carbon Fiber Tubes

Manufactured by wrapping prepreg carbon fiber sheets onto a precision-ground steel mandrel, then curing under controlled heat. This method produces excellent surface quality with the characteristic woven carbon pattern clearly visible.

Available in 3K plain weave, 3K 2×2 twill weave, unidirectional, or hybrid layups. Inner and outer surfaces can be polished to a high gloss or left with a matte finish.

Outer Diameter (OD)	3mm – 100mm
Wall Thickness	0.5mm – 5mm
Standard Length	500mm / 1000mm / 2000mm
Max Custom Length	4000mm
OD Tolerance	±0.1mm
ID Tolerance	±0.15mm
Fiber	T300 / T700 standard
Resin	Epoxy (125°C cure)

3K Plain 3K Twill UD High Gloss Matte Satin

High Tensile Strength

Pultruded Carbon Fiber Tubes

Pultrusion pulls continuous carbon fiber roving through a resin bath and a heated die, producing tubes with unidirectional fiber alignment. The result is exceptionally high axial tensile and compressive strength at a competitive cost for longer runs.

Ideal for structural applications, linear motion, antenna masts, and any design where axial load-bearing is paramount. Tight dimensional tolerances make pultruded tubes suitable for precision assemblies.

Outer Diameter (OD)	4mm – 50mm
Wall Thickness	1mm – 4mm
Length	Up to 6000mm (cut to order)
OD Tolerance	±0.05mm
Tensile Strength	1200 – 1600 MPa
Tensile Modulus	120 – 140 GPa
Fiber	T700 standard
Surface	Resin-rich (smooth)

Custom Wind Angle

Filament Wound Carbon Fiber Tubes

CNC filament winding machines apply fiber at precise angles to create tubes with engineered performance profiles. By adjusting the wind angle (25° to 89°), the balance of axial stiffness vs. torsional and hoop strength can be optimized for your specific load case.

Best suited for larger diameter tubes, drive shafts, pressure vessels, and applications where torsional rigidity or internal pressure resistance is critical.

Outer Diameter (OD)	10mm – 200mm
Wall Thickness	1mm – 10mm
Wind Angle	25° – 89° (customizable)
Length	Up to 3000mm
Fiber	T300 / T700 / T800
Resin	Epoxy or Vinyl Ester
Pattern	Helical / Hoop / Combined
MOQ	1 pc (prototype)

Structural Profile

Carbon Fiber Square & Rectangular Tubes

Roll-wrapped carbon fiber box sections and rectangular profiles for lightweight structural framing. The square cross-section provides resistance to bending loads in multiple planes simultaneously.

Used extensively in drone frames, camera rigs, robotic structures, bicycle components, and custom fabrication projects where a box section is preferred over round tubing.

Cross-Section	5×5mm – 80×80mm
Rectangular	10×5mm – 100×50mm
Wall Thickness	0.5mm – 3mm
Length	Up to 2000mm
Weave	3K plain / twill / UD
Finish	Glossy / Matte
Corner Radius	≈ wall thickness
MOQ	5 pcs

Custom Profile

Oval & Tapered Carbon Fiber Tubes

Beyond standard round and square sections, we manufacture oval, elliptical, tapered (cone), and other custom cross-section carbon fiber tubes. Each requires a purpose-built mandrel or tooling — we can work from your engineering drawing or 3D file.

Common applications include bicycle chainstays and seatstays, fishing rod blanks, sailboat spars, trekking pole shafts, and architectural elements.

Cross-Section	Oval, ellipse, tapered, D-section
Tooling Lead Time	7 – 14 days
MOQ	10 pcs (after tooling)
Taper	Small to large end, custom ratio
Max Length	3000mm
File Format	DXF, STEP, PDF drawing accepted
