Carbon Fiber Tubes

Assorted Carbon Fiber Tubing

 

Carbon Fiber Tubes Deliver Increased Strength and Reduced Weight

Due to their unique properties, carbon fiber tubes are used in numerous applications over traditional materials such as aluminum, steel and titanium.

  -  High strength and stiffness with low weight   

  -  Excellent fatigue resistance 

  -  Dimensional stability: Low to Zero CTE      


 


Types of Carbon Fiber Tubes

Standard Modulus Carbon Fiber Tubing (SM)

This is the most common grade of carbon fiber used for our carbon fiber tubes.  Standard modulus offers excellent strength and stiffness.  It is 1.5X stiffer than aluminum and is the most economical grade.

 

Intermediate Modulus Carbon Fiber Tubing (IM)

Offers enhanced stiffness over standard modulus carbon fiber tubing with the same or better strength.  Intermediate modulus is ~2X stiffer than aluminum tubing.

 

High Modulus Carbon Fiber Tubing (HM)

High modulus carbon fiber is 3X stiffer than aluminum (or equivalent to steel stiffness) and has very similar strength to standard modulus carbon fiber tubing.  This is an excellent choice for demanding, weight sensitive applications.

 

Ultra High Modulus Carbon Fiber Tubing (UHM)

Incredible stiffness at 4-5X aluminum or ~1.5X steel.  Ultra high modulus has lower strength and is not recommended for high stress applications.  

 


Standard Carbon Fiber Tube Options

Virtually any shape can be fabricated using carbon fiber.  These include:

  • Round
  • Square
  • Rectangle
  • Oval, elliptical
  • Octagon, hexagon
  • Custom shapes and profiles

  • Wide range of diameters from 0.060” to over 10”
  • Most common fractional sizes (ID and OD)
  • Tapered diameters
  • Many metric sizes
  • OD grinding add-on service (+/-0.0005”)

Mandrels can be made to order for reasonable costs. 

Carbon fiber tubes are made with layers of prepreg, typically ~0.006” per layer. Virtually any wall thickness can be made by changing the number of layers or combining different prepreg thicknesses (0.003” – 0.010”).    

Common tube thicknesses include:

  • Thin wall: 0.010”, 0.020”
  • 0.035”, 0.041”, 0.058”, 0.064”, 0.092”
  • 1/8”, 1/4” or thicker

 

  • Maximum length is 100” (for most ID sizes)
  • Long lengths:  tubes can be joined together with internal (or external) ferrules to achieve the required length.
  • One-piece longer lengths are possible for larger orders
  • Tubes can be cut to size for an additional charge. 
  • Precision cutting tolerances available (+/-0.010” or better)

Our standard exterior finishes include:

  • Cello-wrap (glossy with resin ridges – natural result from production process)
  • Matte (sanded or centerless ground)
  • Satin (sanded, high grit)
  • Glossy (clearcoat)
  • Painted

Standard exterior materials include:

  • 2x2 twill fabric
  • Plain weave fabric
  • UD (unidirectional)
  • Silver texalium
  • Red/black
  • Blue/black
  • Custom colors/styles:  any fabric that is commercially available can be utilized to make carbon fiber tubing.
