The laminated carbon fibre square tubes are made of prepreg material with a smooth twill fabric finish on the outside and a rough inside. There are 2 types of square tubes in which the orientation of the fibres and material composition are different: Torsion and Stiff. Stiff: stiffness, extra UD material.Torsion: torsionally rigid, thanks to the addition of extra axial material. The density amount of fibres in the standard square tubes is approx. 65%+ which can be used to make lightweight and rigid structures. This carbon square tube 40-40, 1000 mm. weighs 517 grams. There can be some perpendicular tolerance.

Carbon square tubes have a smooth exterior finish and a rough inside. When bonding parts into the tube, always rub off folds and uneven parts. It happens that the connectors only fit into the tube after sanding. We therefore advise you to use the largest possible sanding surface and try to prevent damage.

The square carbon fibre tubes are laminated from prepreg High Strength Carbon fibres and epoxy resin. The outer layer has a "twill" weave with the traditional aesthetic appeal of carbon. The carbon fibres are laminated in different directions in the wall thickness of the tube. This ensures the square tube offers unique stiffness and strength and is also low weight. These carbon tubes are far more resistant to bending than metal variants.
 
The square carbon fibre tubes are available in different variants sizes, the stiff and torsion square tube:

  • The "STIFF" square tube has a high rigidity and minimal bending. The carbon fibres are mainly placed in a longitudinal direction 
  • The “TORSION” square tube has a better torsional rigidity. The carbon fibres are placed in both a longitudinal and torsional direction. This tube also offers high torsional rigidity.
SQUARE Carbon TUBES are available in various dimensions and lengths of 2300 mm and 1150 mm.

Applications:         

Lightweight frames for machine building and product handling systems, lightweight constructions and frames, tube connections, medical equipment and more
 

Production process:        

Laminated from prepreg carbon fibres and epoxy resin
