Roll wrapped carbon fibre tubes with a smooth surface finish of 3k twill weave fabric, clear-coated glossy.Subjacent layers made from unidirectional non-crimp fabric.High qualityepoxy resin matrix. (More information about CFRP-tubes see R&G eWiki)., in german only, translator included).
Fibre orientation:
Surface layer: 0°/90°
Core layers: 0°
Characteristics: Light weight, excellent corrosion and heat resistance and electrical conductivity. Very good flexural and hoop stiffness.
After laminating, the wound CFK round tubes are ground (round) to size and then coated.
Tolerances: Deviation in diameter ± 0.2 mm. As a rule, the deviation from the straightness is not more than 1 mm/m.
These tubes are usually not telescopic or cannot be telescoped without post-processing. Telescopic, cylindrical tubes see here.
